Fast unclamping device realizing oil well drill clamping object directional explosion impact failure separation

Abstract

The invention relates to a fast unclamping device realizing oil well drill clamping object directional explosion impact failure separation. The fast unclamping device comprises an energy-gathering directional large perforating breaking device, wherein the energy-gathering directional large perforating breaking device comprises primer sensitive powder; an energy-gathering powder charging casing is arranged at the lower part of the primer sensitive powder; energy-gathering explosive agents are contained in the energy-gathering powder charging casing; the bottom of the energy-gathering powder charging casing seals and compacts the energy-gathering explosive agents through a hemispherical conical energy-gathering cover; the outer part of the energy-gathering powder charging casing is provided with an auxiliary energy absorption separation layer; the primer sensitive powder of the energy-gathering directional large perforating breaking device is connected with a primer of an ignition initiation device; and the primer I is firstly and directly detonates a detonating fuse for detonating the primer sensitive powder, the primer sensitive powder detonates the energy-gathering explosive agents, and the energy-gathering explosive agents explode so that that the energy-gathering cover forms a high-speed high-temperature metal carrot to directly penetrate through and break a drill clamping object. Through the strong comprehensive effect of drill clamping object directional large perforating breaking, and high-pressure gas directional impact, flushing and collision vibration, the drill clamping object blockage is relieved.

Description

technical field [0001] The invention relates to equipment and devices for solving the situation of drilling tool sticking or downhole tool stuck in the casing during drilling or downhole operation of oil wells, in particular to a quick release device for directional deflagration impact destruction and separation of stuck objects in oil wells. Background technique [0002] In the process of oil exploration, development and production, drilling and oil extraction are two important projects of oil extraction. Accidents such as drilling tools sticking and falling objects often occur in the process of drilling and production of oil wells for downhole operations. , often due to downhole accidents caused by downhole tools, the drilling or oil and water wells cannot be produced normally, especially after the occurrence of downhole sticking and falling objects, the drilling work will be stopped, and major repairs must be carried out. Stop production, and even make oil and water wells...

AI Technical Summary

Problems solved by technology

Downhole stuck pipe accidents and downhole falling object accidents are the main downhole accidents that affect the normal production of drilling and production wells, and are also a large number of common downhole accidents. At present, there are professional overhaul institutions and various downhole maintenance tools, but precisely because of The diversity and complexity of downhole accidents, even unpredictability, new special stuck pipe accidents occur from time to time, such as when the drill bit is changed during the drilling process, the tri-cone bit is accidentally dropped in the wellbore, the original downhole accident The processing tool is difficult to solve the problem, even difficult to handle, the time for overhaul operation is greatly prolonged, the construction cost is greatly increased, and the normal production of drilling or production wells is seriously affected
