一九七六年开始对各种压裂施工动态曲线进行了整理和初步分析,使我们认识到压裂施工的过程,也是进一步认识地下油层的过程。整个压裂施工过程,可以根据不同的目的和作用,分为以下七个步骤。这七个步骤是连续进行的,但是,每一个步骤也有它本身的独立性。循环:每台压裂车,在地面管线系统单独进行循环(不通过井口)。即从供液罐——混砂车——压裂车——高压管汇——供液罐组成一个循环系统,目的是了解供液罐供水 Beginning in 1976, the dynamic curves of various fracturing constructions have been collated and preliminary analyzed, so that we can understand the process of fracturing and also understand the process of underground oil layers. The entire fracturing process, according to different purposes and functions, is divided into the following seven steps. These seven steps are continuous, but each step also has its own independence. Cycle: Each fracturing car is cycled on its own surface pipeline system (not through the wellhead). That is, from the liquid tank - sand mixer - fracturing car - high pressure manifold - for the tank composed of a circulation system, the purpose is to understand the supply tank
