Tripping method for operation by adopting power swivel and tool

Abstract

The invention discloses a tripping method for operation by adopting a power swivel, which is applied to petroleum drilling. The tripping method for operation by adopting the novel power swivel is formed by matching a specially-designed bearable and torsional drill collar elevator, a bearable and torsional elevator, a casing elevator, an existing tubular column lifting tool, a tubular column conveying device and other well mouth tools as well as a power slip and a hydraulic powder toque chain tong device. A tubular column is transferred to the well mouth by matching the tubular column conveying device with the tubular column lifting tool; the power slip is matched with the special bearable and torsional elevator; the fastening and tightening buckle operations are finished through the hydraulic powder toque chain tong device; and the tripping of a tubular column is realized. The invention can simplify operation procedures, reduce the labor intensity of workers, the operation space of the well mouth as well as the sizes of a derrick and a drill floor, and improve the movability of a drilling machine. The invention replaces the traditional method for the tripping operation by adoptingdouble elevators.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling, in particular to a tripping method and a tool for using a power faucet in the exploitation process of petroleum and coal bed gas. Background technique [0002] At present, domestic oil and coalbed methane mining mostly use rotary table + kelly drilling operations, and key wells use top drive operations. There are two main methods for tripping operations: 1) Equipped with hydraulic power tongs: double elevators are required for drilling The tool is lifted and lowered, and the hydraulic power tongs (power drill pipe tongs, power casing tongs) are used to turn, tighten and stretch the buckle. When the power tongs cannot remove the drilling tool when pulling out the drill, use the power cat head to cooperate with the B-type lifting tongs to break out. 2) No hydraulic power tongs: It needs to be equipped with double elevators to lift and lower the drilling tool; the cat head drives the lar...

Problems solved by technology

[0005] The object of the present invention is: the present invention provides a tripping method for power swivel operation, which solves the problem that conventional power swivels cannot be directly used for tripping

Overcome the disadvantages of using traditional tripping methods for power tap operations, such as the use of more tools, the labor intensity of workers, and the large space occupied by the wellhead.
