从1977年起,从美国BJ公司引进的压裂设备在长庆油田投入使用,六年多的生产实践证明,它是一种比较先进的压裂设备。但是,近年来,随着油田的钻探日益向深部地层发展,油井深度不断增加,BJ公司的压裂车却不能很好地适应深井压裂作业的要求。据了解,长庆油田生产井井深一般为1500～2200米;区域探井井深为3800～4500米。根据油田井深和 Since 1977, fracturing equipment imported from BJ Company in the United States has been put into operation in Changqing Oilfield. After more than six years of production practice, it has proved that it is a relatively advanced fracturing equipment. However, in recent years, BJ fracturing trucks have not been well adapted to the requirements of deep well fracturing as oilfield drilling continues to develop deeper into deeper strata. It is understood that Changqing oilfield production well depth is generally 1500 ~ 2200 meters; depth of exploration wells 3800 ~ 4500 meters. According to well depth and depth of oilfield
