Wellhead combination valve group watering gathering and transportation regulation and control device connected through quick connector

Abstract

The invention relates to the technical field of oil field equipment, and discloses a well mouth combination valve group watering gathering and transportation regulation and control device connected through a quick connector, a water inlet pipe is welded to the right side of the outer wall of a mounting shell, a mounting channel is formed in the right side of an inner cavity of the mounting shell, and an inner cavity of the water inlet pipe communicates with an inner cavity of the mounting channel. When the well mouth combination valve group watering gathering and transportation regulation and control device connected through the quick connector is used, water flow impacts a flow guide block which is obliquely arranged to drive an annular block to rotate, so that a mounting plate is driven to rotate, and a cleaning block is driven to rotate and clean the outer wall of a filter shell; under the action of the sliding block and the inner wall of the two-way spiral groove, the mounting plate horizontally reciprocates, then the horizontal position of the cleaning block is adjusted to repeatedly rub and clean the outer wall of the filter shell, and the water is discharged out of the equipment through the sewage discharge channel, so that the problems that the equipment maintenance efficiency is low, the sealing performance of the equipment is easily influenced by repeated disassembly and assembly, and water leakage occurs are solved.

Description

technical field [0001] The invention relates to the technical field of oilfield equipment, in particular to a wellhead combination valve group connected by a quick joint and a water-mixed gathering and transportation control device. 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 to waste energy. Most of the problems are solved by mixing water. Transmission control is the production of heavy oil, high wax content, and low-yield oilfields. The conventional double-pipe mixed hot water transportation technology is mainly used, that is, each oil well corresponds to an oil production pipeline and a hot water mixed water pipeline. Valve, in order to facilitate control and maintenance, the water-mixed gathering and transportation contro...

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
