【摘要】 论述了延长油田长6井组的转注原因及注水前缘微地震监测。延长油田子长采油厂4237井组的注水前缘优势方向为北东东向,受到原地应力场方向影响强烈。研究表明,注采井网的布局应该同时参考原地应力场方向及原有裂缝方向。依据监测结果,油水井布置方向是正确的,应该缩短沿北北西方向的油、水井距,以提高注水见效程度。更多还原

【Abstract】 This paper discusses the long 6 extend oilfield injection wells because the transfer group and the leading edge of microseismic monitoring of water.Yanchang Oil Field Oil Production Plant 4237 Zichang water injection wells set the direction of NEE to the front edge by the impact of in situ stress field in the direction of the strong.That injector network layout should also refer to the in-situ stress field direction and the original crack direction.更多还原
