摘要:

水驱油藏的开发效果受到储层物性条件、开发政策等的影响,需要综合考虑多种因素,才能更为准确地确定油藏可开发潜力大小和挖潜方向。基于油藏工程理论,提出水驱油藏开发潜力的流场分析方法,并建立相应的计算流程,主要包括:通过静态流场评价来分析油藏生产条件,通过动态流场评价来分析油藏开采效果,通过优势剩余油丰度评价来分析油藏开发潜力。利用建立的方法,对实际油田进行了计算和分析。研究结果表明,考虑多种影响因素,从动态、静态两个方面来综合研究油藏开发条件和开采效率,并结合油藏优势剩余油丰度分布规律,可以更好地明确油藏剩余油的主控因素和挖潜方向。

Abstract:

Development effects of water-drive reservoirs are affected by some factors which include physical properties of reservoirs,development policies,and so on.Therefore the development potential and potential tapping direction for the reservoirs can be accurately determined by considering multiple influencing factors in an integrated manner.According to reservoir engineering theory,a flow-field analysis method for the development potential of the water-drive reservoir is proposed.And the corresponding calculation process established includes production conditions of the reservoir analyzed by the static flow-field evaluation,production effect of the reservoir evaluated by the dynamic flow field,and the development potential of the reservoir determined by the evaluation of the dominant remaining oil abundance.Case research results indicate that considering multiple influencing factors,in combination with the distribution rule of the dominant remaining oil abundance,main control factors and potential tapping direction for reservoir remaining oil can be accurately determined by the comprehensive study on the production condition and development effect of the reservoir from both the static and dynamic perspectives.
