Abstract
The invention discloses a dropped initiation device which is suitable for impacted initiation perforating operation transmitted by oil pipes of an oil well. The device consists of a dropped primer and a transmission detonation joint which are independent to each other; the dropped primer consists of a rod body and a rod point which are in screw connection, and a delay firing mechanism and priming system components which are arranged in the rod body and the rod point; the transmission detonation joint is composed of a guide sleeve and a gun joint which are in screw connection, and a booster which is arranged in the gun joint. When in perforating operation, the upper end and the lower end of the transmission detonation joint are respectively connected with the oil tube and a perforating gun; when the transmission detonation joint drops into a destination layer in the well and the dropped primer is dropped to the destination along the oil tube, a cone boss at the upper end of the gun joint is located in a V-shaped hollowness at the lower end of the rod point; after a certain delay, the delay firing mechanism fires the priming system components to output a high speed jet flow; the high speed jet flow passes through the outer wall of the rod point and the gun joint, and then ignites the transmission detonation joint, thereby igniting perforating bullets and finishing the perforating operation. The device is safe, reliable and low in cost.
Description
