低渗透油田抽油井合理注采压力系统研究——以鄯善油田三间房油藏为例

THE STUDY OF REASONABLE INJECTION-PROUDUCTION PRESSURE SYSTEM FOR THE PUMPING WELLS IN THE LOW PERMEABILITY OILFIELD——BY TAKING SHANSHAN OIFIELD SANJIANFANG RESERVOIR AS AN EXAMPLE

注采压力系统是油田开发研究的重要组成部分,任何形式的开发调整和技术政策界限的制定必须在合理注采压力系统范围内进行,才能取得预期效果。针对鄯善油田进入中含水期开发后,在低含水期建立的注采压力系统已不能适应油田开发需要的矛盾,重新研究建立了中含水期合理的注采压力系统,并对油田目前的注采压力系统进行了评价。

Injection-prouduction pressure system is the important part in the study of the oilfield development.It is necessary to establish any form of development adjustments and technical policy limits in the reasonable injection-prouduction pressure system,as thus oilfield development is to achieve the desired results.As Shanshan Oilfield is in the middle-high watercut development stage,the injection-production pressure system established in the low watercut development stage can no longer meet the needs of the development of oilfields at present.Therefore,through restudied the whole oilfield,reasonable injection-production pressure system was established in the middle-high watercut stage,and the current oilfield injection-prouduction pressure system was evaluated.
