摘要
针对传统的油井热洗清蜡工艺的不足,以及抽油泵泵效低的现象,研制了快速洗井增液器。这种快速洗井增液器根据油井结蜡规律下入相应井段,对结蜡部位直接热洗,具有清蜡彻底、洗井液用量少、热量利用率高等特点。同时在正常抽汲过程中,协助抽油泵增大抽汲力,减轻抽油泵的动载,减小间隙漏失量,从而达到增液提效之目的。与套管热洗清蜡相比,歧123-1井采用快速洗井增液器,洗井时间缩短4h,进口温度提高10℃,出口温度提高25℃,漏失量减少12m3,油井恢复正常生产天数减少5d,热洗周期延长30d,日产液增加6m3,日产油增加2t,泵效提高近10％。
To solve problems of thermal paraffin removal and improve the efficiency of deep well pump, a speedy well washing device is developed. The device is located in paraffin area of the well and paraffin is removed directly by means of thermal washing. In addition, the flow rate of the pump is enlarged by increasing draw-in fluid, reducing dynamic load, and decreasing clearance leakage of the pump.
