Discover how Dongsheng anti-sand sucker rod pumps utilize advanced scraping technology and Tungsten Carbide coatings to prevent plunger sticking and extend run-life in high-sand oil wells.

What is Gas Lock? Some oil wells contain a high concentration of gas, which can enter the pump barrel through the fixed valve. If not promptly vented, the gas will gradually fill the space below the plunger in the pump barrel. As the plunger descends, the liquid in the tubing string acts on the traveling valve, exerting significant pressure. This prevents the traveling valve from opening, compressing the gas in the pump barrel below the plunger and preventing the flow of liquid above the plunger. As the plunger ascends, the compressed gas expands, exerting pressure on the fixed valve, preventing it from opening and preventing the pump from drawing liquid. This repetitive cycle of gas compression and expansion without any discharge is called gas lock.

Learn an in-depth understanding of efficient solutions to oil well degassing challenges. I. What is an anti-gas sucker rod pump? An anti-gas sucker rod pump is a type of pumping equipment specifically designed to address high gas content in well fluids. It is an improved version of the sucker rod pump. Its unique structural design and degassing mechanism effectively prevent gas from entering the pump body, resolving the "gas lock" or "gas cap" issues associated with conventional sucker rod pumps and improving oil recovery efficiency.

Deep-well sucker rod pump is a mechanical oil production equipment used for deep well oil extraction, which is a core component of the rod pump oil production system. Anti gas sucker rod pump is a pumping equipment specifically designed for gas-bearing wells, mainly used to reduce or avoid the impact of gas on pumping efficiency. So do you know the difference between them?
