复杂小断块油藏生产测井方法浅析

Brief Analysis on Production Logging Method for Complex Minor Fault Block Reservoir

针对江苏油田GY凹陷东部地区油藏具有断块小、构造破碎、储层连续性差、渗流阻力大、纵向和平面上非均质性严重的特点,分析了油水井"故障"因素:窜槽或套管破漏和层间矛盾,并根据"故障"因素介绍了生产测井方法检测的选择原则、方法。将上述原则、方法在江苏油田进行了现场应用,取得了良好效果,找出了能有效辨别影响油水井生产主要因素的生产测井组合,并根据其解释结果采取相应的措施方案,有效提高了开发效果。

Aimed at the reservoir characteristics such as minor fault block ,fragmented structure ,poor reservoir continuity,large percolation resistance force and serious vertical and areal heterogeneity,this paper analyzes the breakdown factors of oil and water well,that is channeling and casing cracking.Based on this,it introduces on the choice principal and method for production logging test,which are put into field use in Jiangsu Oilfield with a good effect.The production logging combination that can effectively distinguish the major factors affecting oil and water well is found.According to the interpretation result,the corresponding measures are taken,which effectively improves the development effect.
