摘要
针对深度开发油田长关井再利用潜力的不确定性、复杂性和任意性.通过分析长关井形成的原因,建立指标评价体系,在此基础上采用层次分析法与模糊综合评价方法,建立了合理完善的长关井再利用潜力评价数学模型.利用此评价模型对葡萄花油层的长关井再开发潜力进行定性的评价和分级,优选出具有较大治理潜力的长关井.该评价模型为长关井的再利用提供了理论依据,提高了长关井利用率、油田经济效益.
Considering the uncertainty, complexity and arbitrariness in reusable potential of long-time shut-in oil wells, the index evaluation system was established by analyzing the reasons of the formation of these wells. Then,with the integration of Comprehensive Fuzzy Mathematics Assessment Theory and Analytic Hierarchy Process(AHP) method, the prediction model was created to evaluate the potential of long-time shut-in oil wells.Based on this model, the reusable potential of long-time shut-in oil wells in Putaohua oil layers were evaluated and classified, and the oil wells with greatest harnessing potential were selected reasonably. This evaluation model could guide the recovery of these wells in oilfield, and dramatically enhance the utilization of long-time shut-in oil wells and economic benefits.
