Automatic liquid discharging and sand removing separator

Abstract

The invention discloses an automatic liquid discharging and sand removing separator, and relates to the technical field of sand removers, the automatic liquid discharging and sand removing separator comprises a base and a production well inlet pipe arranged at the top of the base, and the top of the base is fixedly connected with a shell; a demulsifier is mounted at the end part of the production well inlet pipe; during installation, only one device needs to be installed, under the condition that normal production of a natural gas well is not affected, the functions of desanding and gas-liquid separation can be achieved, automatic discharging of sand and liquid can be achieved, installation is easy, operation is safe and convenient, the device can achieve the effects that the wellhead pressure is not higher than a rated value, throttling and pressure reduction are not needed, fracturing sand and a large amount of fracturing fluid in wellhead natural gas are directly separated out, the equipment is high in sand removing efficiency, and the continuous sand discharging function can be achieved; and the phenomenon that a large amount of reverse discharge liquid mixed with natural gas is directly discharged to the atmosphere in the initial stage of open flow to easily cause flash explosion danger is prevented, so that the environment is protected to a certain extent, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of sand removers, in particular to an automatic liquid drainage and sand removal separator. Background technique [0002] The desander is a device that separates impurities from gas, water or waste water; the desander is a secondary solid control equipment for drilling fluids. According to the diameter of the cyclone, it is divided into cyclone desander and cyclone desander. Cyclone desilter. Generally, the combination of cyclones above 6″ is called desander, which is the second-level solid control equipment in drilling operations. Commonly used are 10″ and 12″ cyclones, which are mainly used to separate drilling fluid. Solid phase particles with a medium particle size of 47-76μm. According to the size of the processing capacity required by the customer, select several groups of cyclones to form a desander. Cyclone desanders are widely used in oil drilling, non-excavation horizontal directional drilling desa...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the sand remover in the prior art can only remove sand but not discharge liquid. After removing sand, it can only discharge sand manually. liquid, high risk, not environmentally friendly, and high cost, and an automatic liquid drainage and sand removal separator is proposed
