【摘要】 针对喇嘛甸油田进入特高含水开发阶段后，液油比高、耗水量大，可采储量采出程度高、挖潜难度大，层系间含水差异小、结构调整难度大的实际情况，通过对密闭取心资料分析、精细地质解剖、以及进行精细数值模拟计算，研究了各类储层的动用状况及剩余油分布特征；结合室内岩心驱替实验结果，研究了喇嘛甸油田各类储层的无效注采问题。 根据物质平衡原理，研究了合理压力保持水平；采用盈亏平衡经济评价方法与油藏工程分析相结合的方法，研究了老井措施挖潜的经济技术界限。在此基础上，确定了特高含水期水驱开发的技术政策；研究了特高含水期不同类型剩余油的挖潜方法，以及寻找和控制无效注采循环的做法。更多还原

【Abstract】 When the lamadian oilfield is in the high water-cut stage, we found that the oil-fluid ratio, the consuming water volume and the recovery percent of commercial reserves has become high, the water-cut difference between two layers is little, and it is very difficult to improve the recovery potential, as well as the structure adjusting. Regarding to this reality, basis on analyzing the data of the core, as well as the geological section and the numerical model computing, we studied the status of the occupying of every layers and the distribution of remaining oil. We also studied the useless injection and production problem combined with the indoor experiment outcomes.Basis on the material balance method, this paper studied the standard of the reasonable pressure. We also studied the developing potential limits of the old wells by combining the break-even analysis with the reservoir engineering analysis. At last, we fix the technologic policy for water-flood development that in a high water-cut stage. This paper also gives the method of enhancing the recovery potential for a well in high water-cut stage, as well as the method of finding and controlling useless injection and production.更多还原
