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。
In view of the contradiction between input and output in the development of low-permeability reservoirs with complicated strata, lack of data and need to be rebuilt by the whole fracturing, a corresponding fracturing transformation technology is put forward, that is, the well is to be implemented by rolling fracturing in stages and the fracturing Strata, and gradually improve and improve the overall fracturing optimization design. The application of this technology to Shengliwangbei Oilfield Block 52 shows that the reverse formation recognition method is effective and the low permeability marginal reservoir, which is difficult to use in reserves, can be economically and efficiently developed. The development provides a less investment, more productive method of operation.
