压裂防砂技术在胜利油田的研究和应用

压裂防砂技术是完全不同于常规防砂方法的新型防砂工艺，具有防砂和增加产能的双重作用，根据胜利油田近几年在该方面的研究及试验成果，从3个方面（裂缝对缓解或避免岩石破坏的作用，裂缝对降低流体携带微粒运移能力的作用，填砂裂缝地层微粒的机械桥堵作用）总结了压裂缝裂的防砂作用原理，介绍了压裂防砂工程方案要点和现场试验情况以及技术改进建议，压裂防砂技术具有独特的技术优质和巨大的应用潜力。表4参4（谢桂学摘）。

The research and application of FracPac technique in Shengli oil field

FracPac is a new sand-control method, which is quite different from conventional methods. It acts as a technical measure both in sand-control and of stimulation. In this paper, the sand-control mechanism of packed fracture and FracPac plan design method and field tests were summarized based on the studies about the effect of fracture on reducing or avoiding damages of rocks, researches about the effect of fracture on reducing the capacity of fluid moving with micrograins and the experiment and field test results about the effect of packed fractures on mechanically bridging formation micrograins in Shengli oil field, China, and some comments for improving this new technique were given. From the results of studies, the authors hold that this technique is a method with distinctive advantages and great application potentiality.
