Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, an integrated impact screw assembly of the present invention is composed of a bypass assembly 01, an impact assembly 02 and a power and transmission assembly 03. The impact assembly 02 consists of an upper joint 02-1, an outer shell 02-2, an anti-rotation cylinder 02-3, a sealing ring 102-4, an anti-drop cap 02-5, an anti-drop rod 02-6, and a spring 02-7 , sealing ring II02-8, static ring positioning cylinder 02-9, static ring 02-10 and moving ring 02-11. The upper part of the bypass assembly 01 is connected to the drill string, the lower part of the bypass assembly 01 is connected to the upper joint 02-1 in the impact assembly 02; the upper part of the power and transmission assembly 03 is connected to the shell in the impact assembly 02 Body 02-2, the lower part of the power and transmission assembly 03 is connected...

Abstract

The invention relates to an integrated percussion downhole dynamic drilling tool, which includes a bypass assembly, an impact assembly, and a power and transmission assembly. The upper part of the bypass assembly is connected to the drill string, and the lower part is connected to the upper joint in the impact assembly; the upper part of the impact assembly is connected to the lower part of the bypass assembly, and the lower part is connected to the upper part of the power and transmission assembly; the upper part of the power and transmission assembly is connected to the impact assembly Into the outer casing, the lower part is connected to the drill bit. The invention adds an impact assembly inside the screw drilling tool assembly, which can provide axial impact power for the screw assembly without affecting the normal operation of the screw assembly, which can improve the rock-breaking efficiency of the drill bit and reduce the stick-slip vibration of the drill string.

Description

technical field [0001] The invention relates to the technical field of drilling engineering in the petroleum and natural gas industry, in particular to an integrated percussion downhole dynamic drilling tool. Background technique [0002] In oil and gas extraction, oil drilling is increasingly developing into deep formations. As the depth of drilling increases, the formation structure becomes more complex, and the time required to drill a well increases. In order to reduce the drilling cost and reduce the total drilling time, drilling industry personnel have successively invented many drilling speed-increasing tools, such as axial impactors, torsional impactors, etc. These speed-increasing tools have played their respective roles in the actual use of many oil fields, but there are also many problems. [0003] During the drilling process, the impactor is often just an auxiliary rock-breaking tool. It provides axial or circumferential impact force for the drill bit, but the ...
