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?
1. Different design objectives:
Deep-well sucker rod pump:
The core goal is to adapt to the complex environment of deep wells (large well depths), focusing on solving the problems of equipment strength, wear, corrosion and other problems under high loads and long strokes in deep wells, so as to ensure that crude oil lifting can be completed stably in deep wells.
Anti gas sucker rod pump:
The core goal is to deal with the "air lock" problem of gas-bearing wells, reduce the impact of gas on pumping efficiency through special design, and ensure oil recovery efficiency in gas-bearing environments.
2. Different applicable scenarios:
Deep-well sucker rod pump:
It is mainly used for oil wells with large well depths (usually more than a few hundred meters) and low crude oil gas content, focusing on adapting to the physical environment of deep wells (such as high pressure, temperature changes, etc.).
Anti gas sucker rod pump:
It is more suitable for oil wells with high oil-to-gas ratio (regardless of well depth), especially in scenarios where gas entering the pump barrel can lead to "air lock" and reduced oil recovery efficiency.
3. Different structural characteristics:
Deep-well sucker rod pump:
The structure pays more attention to strength and durability, such as using more wear-resistant materials and optimizing the connection between the sucker rod and the pump barrel to withstand the high load and friction in the reciprocating movement of the deep well.
Anti gas sucker rod pump:
The structural design revolves around the "exhaust air lock", and the common special structure includes the installation of gas anchors (separating oil and gas in advance), improving the valve group, setting up gas channels, etc., and giving priority to the discharge of gas entering the pump.
4. Different working principles:
Deep-well sucker rod pump:
The working principle emphasizes "overcoming deep well resistance", by optimizing the fit accuracy of the plunger and the pump barrel, enhancing the rigidity of the sucking rod, reducing the elastic deformation and vibration of the rod and column caused by the well depth in the reciprocating motion, and ensuring that the energy loss is minimized in long-distance lifting.
Anti gas sucker rod pump:
The core of the working principle is "gas-liquid priority separation", before the crude oil enters the pump barrel or during the inhalation process, the free gas or dissolved gas is actively separated and exported out of the pump through the air anchor, exhaust valve and other structures to avoid the gas occupying the volume of the pump barrel.
