Thickening pump reborn

Thickening pump reborn As of December 26, Henan Pumping Oil Plant No. 2 applied two innovative technologies to reform the thickening pump and produced 134 normal days on six viscous oil wells with different viscosity, which was 92 days longer than the previous inspection pump cycle and did not occur. Because the phenomenon of pump inspection was required for pump leakage and sand entry, the pass rate of a downhole pump reached 100%, and the effect of “rebirth” was achieved.

Thickening pump is the main tool for heavy oil extraction in No.2 Oil Production Plant. High sand content, high water content, high temperature vapor heavy oil production leads to heavy pumping. The ball of Versailles and Versails are not sealed tightly and the pump is missing. It is unable to pump normally. The average exemption period is getting shorter and shorter, and some oil wells even less than 30. It is necessary to check the pump every day, which will seriously affect the overall economic benefits of oilfield development. To this end, the plant's scientific and technical personnel implemented two technological innovations. One is to widen the bevel seat sealing bevel to eliminate the possibility of blown Versail balls against the beveled edge of the seal, and to increase the sealing cross-sectional area between the ball and the Versail seat; It is to increase the guide ribs on the inner wall of the Verrer hood, and to straighten the ball in the Verrer hood. Since August of this year, they have tested on six viscous oil wells with different viscosity and achieved good results.

At present, the plant has successively reconstructed 450 heavy oil pumps in waste dumps, saving more than 3.5 million yuan in material purchases. It is reported that two technological innovations have already applied for national patents.
