油田区块整体调剖技术是降低油田区块综合含水上升速度、提高区块阶段采出程度的重要措施。提出了一套适合区块整体调剖的筛选方法,该方法具有选井、选层、选剂、调剖剂用量优化、效果预测和经济评价等功能。选井时采用模糊数学的综合评判技术,调剖剂用量优化采用单井数值模拟优化设计方法,并将国内常用的调剖剂建成了调剖剂库。运用该套技术对区块进行整体调剖筛选具有操作简单、速度快、精度高等优点,适合区块整体调剖筛选的需要。
The overall profile control technology in the oilfield blocks is an important measure to reduce the comprehensive water-bearing rise speed of the oilfield blocks and increase the recovery of the blocks in the block stage. A set of screening methods suitable for the profile control of the whole block is proposed. The method has such functions as selecting well, selecting layers, selecting agent, optimizing dosage of profile control agent, predicting effect and evaluating economic value. The selection of wells using fuzzy mathematics comprehensive evaluation techniques, optimization of the amount of profile control agent using single well numerical simulation optimization design method, and the domestic profile control agent is built into the profile control agent library. The use of the set of techniques for the overall profile of the block profile screening has the advantages of simple operation, high speed, high accuracy, suitable for the overall block profile screening needs.
