Full Dimension Percussive Drilling Speed-Up Tool

Abstract

The invention relates to the technical field of drilling equipment, and is a full-dimensional percussion drilling speed-increasing tool, including an upper body, an upper mandrel, an axial impact component, a mandrel anvil, a lower mandrel, a lower body, a lower joint, and a circumferential impact component. , shunt pressure cap and wear-resistant assembly, the upper inner side of the upper body is hung with an upper mandrel that can rotate relative to it, the lower inner side of the upper body is limited and installed with a lower body that can rotate relative to it, and the inner side of the upper end of the lower body is provided. The ring groove is installed with a mandrel anvil in the inner seat of the ring groove, and the lower part of the upper mandrel is sleeved in the installation ring groove and is positioned above the mandrel anvil. The present invention has a reasonable and compact structure and is easy to use. By setting an axial impact component in the upper body, the downstream drill bit is subjected to a pulsed downward impact during drilling; by setting a circumferential impact component in the lower body, the downstream drill bit During the drilling process, it is subjected to pulsed circumferential impact, and has the characteristics of high efficiency, continuous reliability and long life.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, and is a full-dimensional percussion drilling speed-increasing tool. Background technique [0002] In the process of oilfield exploration and development, increasing the ROP is an eternal goal pursued by the oilfield development industry. At present, many different types of drilling speed-increasing tools have been developed at home and abroad and put into field test applications, and good results have been achieved. Existing drilling speed-up tools mainly achieve the speed-up effect by applying impact to the drill bit. According to the form of impact, they can be divided into axial impact speed-up devices and circumferential impact speed-up tools. [0003] Since both the axial impact acceleration device and the circumferential impact acceleration tool have complex structures, the downstream drill bit cannot be simultaneously subjected to circumferential impact and axial impact during...
