采用机械助排工艺解决了青海尕斯库勒油田N1-N21油藏油井酸化残酸返排施工中其它三种返排技术存在的返排压力低、费用高和效果差的技术难题。现场应用机械助排工艺两井次,残酸返排施工成功率达到100%,残酸排出的有效率达到80%。
The mechanical drainage technology is used to solve the technical problems of low return pressure, high cost and poor effect of the other three kinds of back-flow technology in the oil well acid refluxing process of the well N1-N21 in Qinggasule Oilfield. Field application of mechanical drainage process two wells, residual acid back row construction success rate of 100%, residual acid discharge efficiency of 80%.
