Problems solved by technology

However, the pipeline described in this invention is still a traditional pipeline, and the angle and direction of the pipeline cannot be adjusted at will during the installation process. It is still a tentative connection method, often repeatedly installed and disassembled, and the work intensity and working time are very high.

Abstract

The invention discloses a gas drilling pipe collecting system capable of realizing universal adjustment of angle. The gas drilling pipe collecting system comprises a plurality of adjusting units, wherein the two adjacent adjusting units are connected through a hard pipeline; each adjusting unit comprises a stepless angle-varying mechanism; the stepless angle-varying mechanism is used for adjusting any angles within 360-degree scope along the pipe-collecting radial direction. The gas drilling pipe collecting system can be used for easily, conveniently and randomly adjusting the direction of the sand-draining pipeline, quickly connecting the sand-draining pipeline to the outer side of a well site, avoiding repeated mounting and dismounting, greatly reducing the workload and working strength of the worker, shortening the mounting period, saving the cost of the worker and the use cost of the crane and avoiding the serious consequences, including the stopping of the drilling machine, the prolonging of the drilling period, and the like.

Description

technical field [0001] The invention relates to a gas drilling manifold, in particular to a gas drilling manifold system capable of adjusting the angle in all directions, and belongs to the technical field of oil and gas drilling (drilling) engineering. Background technique [0002] Gas drilling is a drilling method that uses gas as a circulation and sand-carrying medium. Compared with conventional drilling fluid drilling, the bottom hole pressure of gas drilling is much lower than the bottom hole fluid column pressure, and the negative pressure is always maintained during the drilling process. Underbalanced drilling. As a new technology developed and matured in China in the 1980s, gas drilling has formed four main technologies of dry gas drilling (air, nitrogen), atomization drilling, foam drilling and air-filled drilling, which have the advantages of improving mechanical penetration rate and controlling malignant Lost circulation, discovery and protection of reservoirs an...
