油层水力压裂仍然是最有效的方法之一,即增加近井地带的渗透率,使液体强化地流入油井。油层水力压裂方法正沿着工艺过程的完善与泵入油层中的液体成分复杂化的方向发展。一切改进的基本任务是保障油层水力压裂液体在最大范围内对油层的走向和断面发生作用,同是减少液体的非生产损耗和在油井井筒压送时压力的损耗。
Hydraulic fracturing of reservoirs is still one of the most effective ways to increase the permeability of the near-wellbore and allow fluids to flow intensively into the well. The method of hydraulic fracturing of oil layers is developing in the direction of perfecting the process and complicating the liquid components pumped into the reservoir. The basic task of all improvements is to ensure that the hydraulic fracturing fluid in the reservoir exerts its influence on the strike and cross section of the reservoir to the maximum extent and reduces the non-production loss of liquid and the pressure loss during pressure delivery in the wellbore.
