Abstract

The invention discloses a device for carrying out a casing pipe installation operation by a common faucet. The operation device comprises a big hook main hook body, a drill floor clip and hydraulic casing pipe pliers, wherein the drill floor clip and the hydraulic casing pipe pliers are arranged on a drill floor. The device is characterized by also comprising the common faucet which is suspended to the big hook main hook body, a casing pipe clamping head which is detachably fixedly connected with the bottom end of the common faucet, and a casing pipe hoisting clip which is suspended to the common faucet and is positioned below the common faucet and the casing pipe clamping head. The invention also discloses an operation method for the device for carrying out the casing pipe installation operation by the common faucet. The invention has the following beneficial effects that by aiming at a drilling machine which is not subjected to top drive, through the cooperated arrangement of the faucet and the casing pipe clamping head, casing pipe column rotation and mud circulation can be carried out in time according to requirements, production efficiency and safety are improved, and a success rate of casing pipe installation is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum cementing. More specifically, the present invention relates to a device and method for casing running operation using a common faucet. Background technique [0002] According to the design requirements of the drilling well body structure, after each stage of drilling, in order to strengthen the well wall and isolate the oil, water and gas layers, it is necessary to run casing and carry out cementing operations to ensure safe drilling and reasonable oil and gas production. . Casing is the operation of connecting each casing with a length of about 10 meters together one by one to form a casing string, and lowering it to the predetermined depth of the open hole according to the design requirements; the cementing operation is the operation between the casing string and the Cement slurry is injected between the well walls, and the casing string is fixed on the well walls after the cement slurry sol...
