Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation, in particular to a filling and sand prevention wellhead device. Background Art

[0002] With the continuous progress of oil field development, major domestic oil fields have entered the middle and late stages of development. Horizontal well development is a new oil field development method with low comprehensive investment cost and good benefits. It is particularly suitable for the exploitation of residual oil in old oil field areas. Due to the high water content in the exploited oil wells, they need to be filled with gravel.

[0003] Due to the frequent use of sand control equipment, the operators will clean the filter pipes in the equipment. Since the filter pipes need to be cleaned to ensure the working efficiency of the sand control equipment, bolts and nuts are usually used to fix the pipes on the outside of one end where the filter pipes are installed. Such pipe fixation may become loose during daily use due to improper installation by the operators, which will reduce the working efficiency of the sand control equipment and make the filling of the equipment incomplete.

[0004] In view of this, we propose a filling and sand control wellhead equipment. Utility Model Content

[0005] The utility model aims to provide a filling sand prevention wellhead device to solve the problems raised in the above background technology.

[0009] A movable rod is movably connected to the surface of the fixed column, a sleeve block is movably installed in the square hoop, and a rubber wheel is movably connected to one end of the movable rod away from the fixed column.

[0010] Preferably, a buckle mechanism is provided on one end surface of the device body, and a movable groove is opened on one end surface of the device body.

[0011] Preferably, a cylinder is fixedly mounted on the inner surface of the movable groove, and a connecting column is fixedly mounted on the surface of the cylinder.

[0012] Preferably, a movable round block is slidably sleeved on the surface of the connecting column. In order to make the blocking block fall off better and separate the block from the device body better, a cap block is fixedly installed on one end of the connecting column away from the movable round block.

[0013] Preferably, a block is fixedly mounted on the surface of one end of the pipe, a long column is movably connected inside the block, a small spring is sleeved on the surface of the long column, and a clamping block is fixedly mounted on one end of the long column to better fix the sleeve block.

[0015] Compared with the prior art, the utility model provides a filling sand control wellhead equipment, which has the following

[0016] Beneficial effects:

[0017] 1. In order to make the pipeline connection more stable, the filling sand control wellhead equipment is equipped with a clamping mechanism to cooperate with the movement of the motor, moving block, square hoop, movable rod, sleeve block and rubber wheel. When the motor is started, it will drive the moving block to move, the movement of the moving block will drive the square hoop to rotate, the rotation of the square hoop will drive the movable rod to move, and the movement of the movable rod will cause the rubber wheel to tighten and loosen the pipeline, thereby achieving the fixation of the pipeline and ensuring the working efficiency of the sand control equipment.

[0018] 2. In order to achieve a better pipeline connection effect, the filled sand prevention wellhead equipment is provided with a snap mechanism to cooperate with the movement of the movable groove, the movable round block, the cap block, the square, the long column, the small spring and the card block. When the pipeline and the device body are fixed, the square will be inserted into the movable groove, and the long column, the small spring and the card block in the square will snap onto the lower surface of the cap block. When the square is pressed again, the card block will move against the movable round block, and the card block and the cap block will fall off, thereby achieving the fixation and disassembly of the pipeline and the device body and improving the connection effect.
