Sand gas anchor

Product description

 

After the oilfield enters the middle and late stage development, with the development of oil wells, due to the decrease in formation pressure, the dissolved gas in crude oil tends to precipitate prematurely, reducing the fullness of pumping pumps, reducing the pumping efficiency, and even causing air locks. In addition, due to loose cementation of the formation, excessive production pressure difference, and other factors, often lead to sand formation in the formation, resulting in increased wear and tear on the pump, stuck pump, and affect the normal production of oil wells. In view of the above problems, we have developed a new type of sandy air anchor. The sand-settling gas anchor structure is novel, simple, and reliable. It adopts the principle of spiral separation and slippage separation, which enables the liquid flow to achieve two-stage separation during the circulation in the pipe, and can prevent the well-washing fluid from pouring into the formation during well-washing. It plays the role of oil layer protection.

The settling gas anchor is composed of the upper joint, the fluid distribution, the central pipe, the spiral plate, the umbrella cap, the lower joint and other components. The liquid flow enters the central tube from the sieve hole in the upper part of the outer tube through the spiral plate and the umbrella cap. At this time, the air bubbles in the liquid are affected by the spiral centrifugal force and gravity differentiation, and they float on the outer wall of the central tube to the suction sieve, and are discharged into the casing and tubing annulus during the downstroke of the plunger. The sand particles sink under the centrifugal force and gravity. Go to the tail pipe of the pump to achieve a separation. The liquid flows from the central pipe, the diverter pipe to the oil jacket annulus, and enters the pump from the side hole of the diverter pipe. During the circulation of the liquid flow in the shunt tube, due to the effects of gravity and slippage, the air bubbles are discharged upward into the annulus of the oil jacket, and the sand particles settle down into the pocket of the oil well, completing the secondary separation of the gas sand.

Instructions for use

 

Immediately below the pump is the sand-settling gas anchor, which is run into the well with the pump. It should be operated smoothly during the run-in process, and the lowering speed must not be too fast.
A tail pipe with a length of 100-200 meters can be connected below the sandy air anchor, and the length of the tail pipe can be adjusted according to the sand production.
