小型压裂技术的应用

在加砂压裂施工前进行小规模压裂，能使加砂压裂更加有效。通过对近两年来胜利油田应用小型压裂指导压裂设计的4口井实例的总结，说明了为确保加砂压裂施工的成功，尤其对端部脱砂压裂设计，小型压裂必不可少。同时介绍了Nolte方法和步骤，及小型压裂为加砂压裂设计提供的必要参数，讨论了参数解释的影响因素。为配合小型压裂工作，全面提高压裂技术水平，应选部分井进行岩石力学参数解释工作、适当延长压降测量时间，并测出瞬时停泵压力等。

Application of Small Scale Fracturing Technology

Before sand fracturing,implement of small scale fracturing can make sand fracturing more effective. After using small scale fracturing on 4 wells in resent two years, we found that in order to insure the success of sand fracturing, especially for the design which the fracture with end sand fall out the small scale fracturing in unnegletive. in this paper, note method steps and the necessary parameters which the small scale fracturing provide to the sand fracturing are also introduced the effect factors on prameter interpretation are also discussed.In order to operate the small scale fracturing and make a high technology level,it is necessary to select some well to analyze the rock mechanical parameters,to extend the pressure drowdown test time and to test the transient pressure.
