Inclined Well Sucker Rod Pump
Inclined well sucker rod pump
Inclined well sucker rod pump is widely used in oil production because it can reduce process investment. Due to the high frequency of use of regular rod pumps in inclined wells, friction is inevitable during use, which leads to wear between the tubing and the casing and between the tubing and the sucker rod. Rod pumps are especially susceptible to decoupling and damage due to wear.
The inclined well pump is manufactured with optimized structure on the basis of the ordinary tubular pump. This pump not only has all the characteristics of ordinary tube pump, but also has higher pump efficiency than ordinary tube pump.
Structure and characteristics: The inclined well pump is usually composed of pump barrel assembly, short plunger assembly, fixed valve assembly and return spring.
The plunger closing valve cover and the pump barrel valve cover of the inclined well pump adopt the structure with guide ribs, which reduces the swing amplitude of the valve ball when it is lifted and lowers, and effectively solves the problem of the valve ball closing lag. Meanwhile, a return spring is added to the valve cover to accelerate the return of the valve ball to the seat seal, significantly improving pump efficiency.
Inclined well pump is widely used in oil exploitation, and it has the following advantages:
Inclined well pumps are widely used in oil production because they reduce investment in the process. The sucker rod pumping technology is the most widely used at home and abroad.
1). Improve oil recovery efficiency
Oil exploration is expensive. The shaft construction method has high technical requirements and great difficulty. Deviated wells are much less difficult to produce. Due to the inclined well mining, the depth does not need to be too deep, and the mining difficulty will be greatly reduced. Secondly, the rod pump is used for oil pumping, the drilling and oil production speed is fast, and the production efficiency is high.
2). Reduce production loss
Inclined well oil production method has low slope, little difficulty in pumping, and almost no leakage during oil production. Rod pump using inclined shaft
3) Safe and efficient oil extraction.
Inclined shafts have disadvantages. There will be friction during use, and friction will cause wear. Wear occurs between tubing and casing, and between tubing and sucker rods. Rod pumps are especially susceptible to decoupling and damage due to wear.
To this end, Sanjack specially designed downhole pumps for deviated wells. The forced shut-off of the inclined well pump improves the situation that the pumping efficiency of the conventional tubing pump is greatly reduced when pumping water in the inclined well. It is suitable for oil production in inclined wells with an inclination angle of less than 45°.
Apply to the oil well with high gas cut.
Degree of inclination of oil well＜45°
1). The downhole step of the inclined well pump is the same as that of the ordinary tube pump.
2). Use a gauge to check the pipeline before turning off the pump.
3). It is strictly forbidden to use it beyond the strokes.
4). Do not use at or below the inflection point.
5). Require a screen to be connected under the pump.
6). When used in sand wells, a sand control device must be equipped under the pump for sand control.
7). It cannot be used in oil wells with high gas content.
