Abstract

The invention relates to the technical field of oil exploitation equipment, and provides an integral casing head of oil well drilling and production equipment. The integral casing head comprises a shell and an oil tube hanger, wherein the shell is used for being connected with a Christmas tree, the oil tube hanger is arranged in the shell, and the integral casing head further comprises a holding assembly for preventing a casing from moving up and down, the holding assembly comprises a connecting pipe, a first sliding block, a second sliding block, a connecting rod and a rotating rod, the connecting pipe is arranged outside the sleeve in a sleeving manner, the first sliding block and the second sliding block are both arranged on the shell in a sliding mode, the first sliding block and the second sliding block move synchronously relative to the sleeve and are opposite in direction, two ends of the connecting rod are connected with the first sliding block and the connecting pipe, the rotating rod is rotationally connected with the shell, and the first sliding block pushes the second sliding block to move reversely through the rotating rod. According to the technical scheme, the problems of high oil production cost and low oil production efficiency caused by the fact that a slip type casing hanger cannot tightly hold a casing in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation equipment, in particular to an integral casing head of oil well drilling and production equipment. Background technique [0002] A complete set of wellhead and Christmas tree is mainly composed of casing head, tubing head and Christmas tree. When drilling, the blowout preventer is installed on the upper part of the casing head to form the drilling wellhead device; when the well is completed, the Christmas tree is installed above the tubing head to form the oil production wellhead device. Among them, the function of the casing head is to connect the surface casing, hang the multi-layer casing in the well, and seal the annular space between the casing and the casing; the main function of the tubing head is to hang the tubing and seal the gap between the tubing and the casing. Annular space; the main function of the Christmas tree is to switch, control and guide oil flow and seal the tubing...
