低渗边际油藏压裂技术研究与应用

HYDRAULIC FRACTURING APPLICATION STUDY FOR STIMULATION OF MARGINAL AND LOW PERMEABILITY RESERVOIRS

  • 摘要: 针对地层复杂、资料缺乏且需整体压裂改造的低渗油藏开发中投入与产出的矛盾,提出了相应的压裂改造技术,即将井分阶段实施滚动压裂改造,通过压裂来认识地层,逐步完善与提高总体压裂优化设计。该技术在胜利大王北油田大52块的应用结果表明,这种逆向认识地层的方法是有效的,使储量难以动用的低渗边际油藏能得到经济高效的开发,为今后低渗边际油藏的开发提供了少投入、多产出的可操作方法。

     

    Abstract: A related hydraulic fracturing stimulation technology is supplied in this paper to decrease operating cost and improve productivity of low permeability reservoir in which there are not enough data and the reservoir geology condition is complex. While running the technology, the whole well formation interval is fractured orderly in steps, the formation is recognized during the fracturing operation at different step, and improves the overall level of hydraulic fracturing technology by use of previous study result. This technology has been used in No. 52 oil bearing block of Shengli Wangbei Oil Field. The result shows the way to deeply study formation is very effective, which is an inverse way to know the formation condition. In this way, many difficult developing reservoirs in which they are marginal and low permeability reservoirs can be developed in a high efficiency manner. Therefore it offered a lower cost and more operative method to develop above related reservoirs in the future.
