油层水力压裂是一种最有效、发展最快的强化采油方法。深部水力压裂既可以处理近井底地带,又可以处理油层。俄罗斯从上世纪50年代开始,采用油层水力压裂方法来提高原油产量,并将此工艺逐步发展成深部水力压裂,这对于开采低渗透分层油藏来说是最强有力的手段。
Hydraulic fracturing is one of the most effective and fastest growing oil recovery methods. Deep hydraulic fracturing can handle both the near-wellbore zone and the reservoir. Since the 1950s, Russia has adopted the method of hydraulic fracturing of oil layers to increase crude oil production and gradually developed this process into deep hydraulic fracturing, which is the most powerful method for mining low-permeability stratified reservoirs.
