A kind of wellhead combined valve group water mixing gathering and transportation regulating device connected with quick joint

Abstract

The invention relates to the technical field of oilfield equipment, and discloses a water mixing collection and transportation control device for a wellhead combined valve group connected with quick joints. A water inlet pipe is welded on the right side of the outer wall of the installation shell, and the inner cavity of the installation shell is opened on the right side. There is an installation channel, and the inner cavity of the water inlet pipe communicates with the inner cavity of the installation channel. When the wellhead combined valve group connected with the quick joint is used, the water flow will impact the obliquely arranged diversion block to drive the annular block to rotate, thereby driving the installation plate to rotate the transmission cleaning block to rotate and clean the outer wall of the filter shell. , Under the action of the slider and the inner wall of the two-way spiral groove, the mounting plate is reciprocated horizontally, and then the horizontal position of the cleaning block is adjusted to repeatedly rub and clean the outer wall of the filter shell, and discharge the equipment through the sewage channel, avoiding the low maintenance efficiency of the equipment. . Repeated disassembly and assembly will easily affect the sealing of the equipment and cause water leakage.

Description

technical field [0001] The invention relates to the technical field of oilfield equipment, in particular to a water-mixing gathering and transportation regulating device for a wellhead combined valve group connected by a quick joint. Background technique [0002] Crude oil gathering and transportation is a key part of the entire crude oil production, and the transportation temperature is set according to the freezing point of crude oil, and it is necessary to control the temperature of crude oil. Conventional heating is a way of wasting energy. Most of the problems are solved by mixing water. Transportation regulation is that the production of oil wells in oilfields with heavy oil, high wax content and low production mainly adopts conventional double-pipe hot water mixing transportation technology, that is, each oil well corresponds to an oil production pipeline and a hot water mixing pipeline, and water mixing is set through the production wellhead of the oil well. Valve, i...

Problems solved by technology

[0003] When the common water-mixed gathering and transportation control device is in use, the electromagnetic valve installed on the water inlet main pipe controls the hot water to enter the gathering and transportation control box, and then controls the water flow into the oil well through the corresponding solenoid valve according to the water-mixing pipeline of the corresponding oil well. In order to ensure the purity of the mixed water and avoid the pollution of the oil well, the scale and pollution produced by the reaction of various substances in the heated water and the impurities attached to the inner wall of the water pipeline are eliminated through the filter screen installed in the gathering and transportation control box. However, after long-term use of the filter screen, the mesh holes will be blocked by scale and dirt. Traditionally, the equipment needs to be stopped and used to disassemble it with external tools to clean or replace the filter screen, resulting in low equipment maintenance efficiency. Repeated disassembly and assembly will easily affect the sealing of the equipment and cause water leakage, which cannot meet the working requirements of the water-mixed gathering and transportation control device. For this reason, a wellhead combined valve group connected by a quick joint is proposed. Water-mixed gathering and transportation control device
