压裂液伤害治理技术

DISPOSAL TECHNIQUE OF FRACTURING FLUID DAMAGE

近年来吉林油田压裂增产措施频繁，压裂液对部分油井的地层造成了严重伤害，从而影响了压裂效果．针对压裂液伤害的原因开展大量的室内试验，研制出一种解除压裂液伤害的地层处理液ＹＬ—１，并完善了现场工艺配套技术．７３口井的现场试验证明，该技术有效率较高，增油幅度大，达到了解除压裂液残渣伤害及蜡堵、水堵、乳化堵的目的．

In recent years,fracturing stimulation is frequently conducted in Jilin Oilfield,serious damage of fracturing fluid to formation has influenced fracturing result in part of the oilfield.According to cause of fracturing fluid damage,large number of indoor tests are done. A fracturing fluid damage treatment fluid YL-1 is developed and required techniques are come to perfection.It has also been proven through the field test in 73 wells that the technique has higher efficiency,high oil production increase and can relieve damage of fracturing fluid residua,wax plugging,water blocking and emulsifying plugging to formation.
