Definitions
- This invention relates to apparatus for sensing the temperature of fluid . flow within a pipe in general, and to apparatus that can be used to non-intrusively sense fluid flow temperature within a pipe in particular.
- Fluid flow within a production pipe is hostile to sensors in direct contact with the fluid flow. Fluids within the production pipe can erode, corrode, wear, and otherwise compromise sensors disposed in direct contact with the fluid flow.
- the hole or port through which the sensor makes direct contact, or through which a cable is run is a potential leak site. There is great advantage in preventing fluid leakage out of the production pipe.
- Second, the environment in most wells is harsh, characterized by extreme temperatures, pressures, and debris. Extreme temperatures (hot or cold) can disable and limit the life of electronic components, particularly those in contact with the fluid.
- Extreme temperature gradients between the fluid flow and the ambient environment can also undesirably influence the accuracy of a temperature sensor.
- An unprotected sensor disposed outside of a production pipe will likely be subject to thermal gradients between the fluid flow and the ambient environment; e.g., a subsea well application can have production pipe fluid temperatures up to and beyond 200 degrees Celsius (°C) and ambient ocean environment temperatures of approximately 2-3 °C.
- the unprotected sensor may be influenced more by the ambient temperature than by fluid temperature inside the production pipe.
- Sensors disposed outside of the production pipe may also be subject to debris and environmental materials such as water (fresh or salt), mud, sand, etc.
- the well environment makes it inconvenient and/or expensive to access most sensors once they have been installed and positioned downhole.
- an apparatus for sensing the temperature of a fluid being drawn from a well includes a pipe having a wall, a sensor mounted on the outer surface of the pipe wall, a thermal insulator, and a housing attached to the pipe that encloses the sensor and the insulator.
- the fluid to be sensed is drawn from the well through the pipe.
- the thermal conductivity of the pipe wall is substantially greater than that of the insulator.
- the housing forms a pressure vessel with the pipe, and the insulator and the sensor are disposed within the pressure vessel.
- Gases such as air, nitrogen and argon are favorable insulators, although other insulators can be used alternatively.
- the pressure of the gas within the pressure vessel can also be varied to suit the application; e.g., lesser or greater than ambient.
- the sensor mounted on the pipe and housed within the sensor housing can be any type of thermal sensor capable of sensing fluid temperature through the wall of the pipe with adequate sensitivity. In the most preferred embodiment, the sensor is a fiber Bragg Grating (FBG) type optical sensor.
- FBG fiber Bragg Grating
- An advantage of the present invention is that a compact apparatus for measuring temperature within a well is provided.
- the present invention fits compactly on the exterior of the production pipe and is therefore easily placed witmn the casing of a well.
- Another advantage of the present invention is that it measures temperature of the fluid in a non-intrusive manner.
- the sensor mounted on the outer surface of the pipe does not require an opening extending into fluid flow path. As a result, a potential leak path into or out of the fluid flow path is eliminated.
- the sensor is protected from the fluid flow within the pipe.
- the present sensor is also protected from the environment outside of the production pipe by the housing.
- the housing protects the sensor from fluid and debris that enters the annulus between the pipe and the well casing.
- the housing also protects the sensor by insulating it from elevated temperatures and pressures, and pressure variations present in the annulus.
- the present invention can use a wider variety of sensors than would otherwise be possible.
- the sensor is disposed within a pressure vessel, the sensor is subjected to a substantially constant pressure. Variations in the pressure outside of the pressure vessel that might influence the sensor are effectively eliminated. For all of these reasons, the reliability and durability of the sensor is accordingly improved.
- Another advantage of the present invention is that it has increased thermal capability over most temperature sensors currently used in a well application.
- the arrangement of the sensor mounted on the outer surface of the pipe where it is protected by the housing permits the use of optical sensors such as a FBG that have a thermal capacity higher than most conventional sensors used in well applications.
- Figure 1 is a diagrammatic view of a well having a casing and a pipe, and present invention thermal sensors positioned at various locations along the exterior of the pipe inside the casing;
- Figure 2 is a diagrammatic cross-sectional view of the present invention apparatus for sensing temperature.
- a pipe arrangement 10 for use in an oil and/or gas production well includes a casing 12 which lines the well bore and a production pipe 14 ("the pipe") disposed inside the casing 12.
- An annulus 15 is formed between the pipe 14 and the casing 12.
- the pipe 14 includes apparatus 16 for sensing the temperature of fluid traveling within the pipe 14.
- the apparatus 16 includes a sensor 18, an insulator 20, and a housing 22.
- the sensor 18 is disposed outside the pipe 14, mounted on an outer surface 24 of a wall 25 of the pipe 14.
- the insulator 20 substantially surrounds the sensor 18.
- the term "mounted on”, as it is used herein to describe the relation between the pipe 14 and the sensor 18, is defined to include direct or indirect connection between the sensor 18 and the pipe outer surface 24.
- Direct attachment exists when a surface of the sensor 18 is in physical contact with the pipe outer surface 24.
- Indirect attachment exists when there is little or no direct physical contact between the sensor 18 and the outer surface 24 of the pipe 14, but there is a thermally conductive medium disposed between the sensor 18 and the outer surface 24 of the pipe 14 that provides a thermal path to the sensor 18.
- the sleeve 26 protects the sensor 18, and attaching the sleeve 18 at one end reduces the possibility that mechanical or thermal strain that develops in the sleeve 26 will transfer to the sensor 18.
- the thermal path to the sensor 18 is primarily through the sleeve 26.
- the sensor 18 is attached to a member 28 made of a material that has thermal properties similar to those of the sensor 18 (e.g., thermal expansion coefficient, thermal response, etc.).
- That member 28 is then disposed in the sleeve 26 that is attached to the pipe outer surface 24.
- the sensor 18 is a FBG
- a member 28 consisting of a glass material e.g., quartz, fused silica, etc.
- the member" 28 to which the sensor 18 is attached reduces the possibility that mechanical or thermal strain developed in the sleeve 26 will be transferred to the sensor 18.
- the housing 22 is attached to the pipe 14 and encloses the insulator 20 and the sensor 18 against the pipe 14.
- the housing 22 includes a panel 30 extending between a pair of bosses 32,34.
- the panel 30 and bosses 32,34 preferably extend around the entire circumference of the pipe 14, although it may be acceptable in some instances to extend only a portion of the circumference.
- a sensor cable 36 extends through a sealable port 38 in one or both bosses 32,34 and connects with the sensor 18. Outside the housing 22, the sensor cable 36 is housed in a protective conduit 40 that is attached to the pipe 14.
- the housing 22 forms a pressure vessel with the pipe wall 25.
- the pressure within the pressure vessel may be greater than or less than the ambient pressure within the annulus 15 between the casing 12 and the pipe 14.
- the pressure vessel is built to withstand pressure gradients present in the well environment.
- the housing 22 is sealed to contain and protect the insulator 20, but does not act as a pressure vessel.
- the size and structure of the housing 22 are chosen to withstand the pressure gradients present in the well environment, to accommodate the size of the sensor 18, and to allow the sensor 18 to be positioned a distance away from the housing 22 such that heat transfer via the pipe 14 and/or the housing 22 is non-disabling for the application at hand.
- the insulator 20 is a material that: 1) has a thermal conductivity less than that of the pipe 14; 2) does not interfere with the operation of the sensor 18; 3) will not functionally degrade in the well environment for a useful period of time; and 4) can withstand the temperatures and pressures present within the well environment.
- the insulator 20 is a material capable of acting as an effective acoustic isolator for the application at. hand.
- An insulator 20 in fluid form can be disposed within the housing 22 at a pressure greater than, equal to, or less than ambient pressure.
- the insulator 20 consists of a gas such as air, nitrogen, argon, or the like.
- An advantage of a gaseous insulator 20 is that it provides favorable acoustic isolation that helps reduce pressure wave interference that might otherwise travel into the housing 22 from the annulus 15 between the casing 12 and the pipe 14 and undesirably influence the sensor 18.
- Heat transfer from the ambient environment to the sensor 18 at a rate that will interfere with the sensing of the fluid within the pipe 14, is avoided by spacing the sensor 18 a minimum acceptable distance away from each boss 32,34 and by disposing an appropriate amount of insulator 20 in the space between each boss 32,34 and the sensor 18.
- the minimum acceptable distance accounts for thermal energy transferring from the ambient environment heat through each boss 32,34 and through the pipe 14 itself. The minimum acceptable distance will vary depending on the application, and can be adjusted to fit the application at hand.
- the sensor 18 is a temperature sensing device having a predictable, repeatable response in the temperature range expected within a well, that is capable of sensing fluid temperature through the wall 25 of the pipe 14 with adequate sensitivity.
- the sensor 18 is an interferometric type fiber optic sensor.
- the sensor 18 is a fiber Bragg Grating type (FBG) optical sensor.
- the FBG is a type of fiber optic strain gauge that exhibits favorable thermooptic effects in response to temperature change. Because strain within the FBG can be induced mechanically and or thermally, it is preferable to attenuate (or eliminate if possible) any sources of mechamcal strain that might affect the FBG.
- mechanical strain within the FBG emanating from various sources is attenuated to an acceptable level by the attachment scheme described above utilizing a glass member 28 disposed within a sleeve 26.
- the pressurized vessel embodiment of the present invention also attenuates mechanical stress by substantially isolating- the FBG from any pressure variations that might occur in the annulus 15 between the pipe 14 and the casing 12.
- mechanically induced strain existing above the minimum acceptable level can be identified and quantified, then it may be acceptable in certain instances to have that level of mechanical strain provided it can be distinguished from the thermally induced strain.
