氧化还原电位法在复杂岩性油藏开发中的应用

APPLICATION OF OXIDATION-REDUCTION POTENTIAL METHOD IN THE DEVELOPMENT OF COMPLEX LITHOLOGIC RESERVOIR

应用氧化还原电位法测定含油富集区 ,在大庆外围榆树林油田进行了试验研究。开展了区域大剖面、典型剖面以及面积网格等不同方式的电位异常剖面的测定 ,建立了一套电位异常模式与含油富集性的关系 ,以适合该类油田经济有效开发的需要。通过重复性的检验 ,在诸因素分析的基础上有效地消除了干扰 ,提高了电位测量精度。在地震、地质、测井综合研究的基础上 ,应用该技术在区块优选、开发控制井的部署以及预测单井产量方面取得了较好的效果。

This paper uses oxidation reduction potential method to determine oil enrichment area and performs a pilot test in Yushulin Oil Field in the peripheral part of Daqing. After repeated examination, this method eliminates the disturbance based on multi factor analysis and increases the potential measurement accuracy. It also obtains a nice effect in block optimizing selection, arrangement of development controlling wells and prediction of single well production.
