Abstract: The remaining oil in the fault edge of Lamadian oilfield is relatively enrichment. Conventional methods cannot accurately describe the fault structure features. Therefore, in this text using the combination of well and seismic technology as the core, multidisciplinary reservoir fine description as method, structural characteristics is studied, the remaining oil is quantified, and the residual oil along fault is tapped by taking the high angle directional well. Since 2009, 12 high angle directional well are successively designed in the 37#, 51# and 15# fault edge, which has made good effects. Through the analysis of high angle directional well development effect, the high angle directional well technology characteristics and the tapping type of potential of residual oil were determined. By optimizing the adjustment measures, the longterm development of high angle directional well was effectively guaranteed. At the same time, the large fault edge remaining potential was further defined, which provide a basis for the development of fault edge and increase of water flooding recoverable reserves.

摘要： 喇嘛甸油田断层边部剩余油相对富集,常规研究方法无法准确描述断层构造特征。为此,以井震结合技术为核心,以多学科油藏为手段,精细描述构造特征,量化剩余油,采取大斜度定向井挖潜了断层边部剩余油。2009年以来,先后在37# 、51# 和15# 断层边部优化设计了12口大斜度定向井,取得了较好的开发效果。通过对大斜度定向井开发效果分析,明确了大斜度定向井的技术特点及挖潜剩余油类型;通过优化措施调整,有力地保障了大斜度定向井长期高效开发;同时,进一步明确了大断层边部剩余潜力,为改善断层边部开发效果,增加水驱可采储量提供了依据。
