在油井的钻井、完井、生产和增产处理过程中,水在油层的近井地带聚集,造成地层水堵,降低油井产量。为了消除地层水堵,俄罗斯在萨莫特洛尔油田用0.1%～1%的阳离子表面活性剂的烃溶液,对油井进行憎水处理,结果解除了油层水堵,使油井的产油量大幅度上升,含水明显下降。油井憎水处
During well drilling, completion, production and stimulation processes, water accumulates in the near-wellbore of the reservoir, causing formation plugging and reducing well production. In order to eliminate formation plugging, Russia used a hydrocarbon solution of 0.1% to 1% of cationic surfactant in the Samoterol oil field to treat the well water-repellent. As a result, water plugging was removed and oil production was large Amplitude increased, water decreased significantly. Well water repellent
