油藏最大接触位移技术在海上注水油田开发中的应用

The application of maximum reservoir contact technology in the development of Offshore water injection Oilfield

为充分利用海上平台井槽,提高油井开发效率。油藏最大接触位移技术可增加原井眼附近油藏泄油面积,具有低成本、高收益等优势。W1井应用该项技术,复产初期该井含水从96.4%下降到89.0%,产能从15bbl/d/psi增加到22bbl/d/psi。分析认为油藏最大接触位移技术,可有效提高油井井周剩余油动用程度,对水平井开发效率提高有显著作用。

In order to make full use of offshore platform well slots,improve oil well development efficiency.The maximum reservoir contact technology can increase the oil drainage area of the original well bore,and has the advantages of low cost and high income.The technology is applied to the well1,which at the initial stage of recovery,the water cut decrease from 96.4%to 89.0%,the productivity is increase from 15bbl/d/psi to 22bbl/d/psi.The analysis shows that the maximum reservoir contact technology can effectively improve the degree of remaining oil production around,and has a significant role in improving the development efficiency of horizontal wells.
