Infilling Method of Well Pattern Suitable to Imbibition Oil Recovery for Fractured and Extra Lower Permeability Oil Reservoirs
Abstract In view of the features of the remaining oil after a periodof production since secondary infilling adjustment of water flooding development oil field, that is, low quality, unbalancedplanar distribution and high vertical dispersal, study on tertiaryinfilling adjustment optimized well spacing has been carried out . The study has solved the problems of reasonable well spacing density, injector-producer distance, injection-production system, how to locate wells near old injector array,and how to adjust and integrate with the original well pattern, with the tertiary recovery well pattern and with the injection-production system. The overall strategy and optimized wellspacing method for tertiary infilling adjustment have beenbrought forward consisting of reasonable well location regiondivision →balanced well spacing →well by well scanning →local adjustment →step by step implementation. The studyhas a wide guidance for the tertiary infilling adjustment of other blocks to find practical, feasible and effectiveapproaches.
加密井网在裂缝性油藏和超低渗透油藏中的应用
【摘要】鉴于剩余油特点，经过一段时间的生产，因为二次加密调整注水开发油田，这就是低质量的，不平衡的平面分布和高垂直分散，研究优化三次加密调整井距以进行外部的调整。该研究解决的问题是合理井网密度，生产井的距离， 注采系统，如何找到水井附近的旧注水井阵列，并研究如何调整和整合原井网，与三次采油模式以及注水井的生产系统。总体战略和优化井距方法，三次加密调整已提出了合理的组成以及位置区域→平衡以及良好的间距以及扫描→调整→地方一步一步实施。这项研究具有广泛的指导意义，并为三次加密调整的其他区块找到实际的、可行的和有效的办法。
