摘　　要：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,低含水期以自喷井为主建立的注采压力系统已不能适应油田中含水期以抽油井为主的开发需要的矛盾,以油藏工程和采油工程基本原理为基础,从采油和注水系统(从地下到井筒到地面)入手,研究建立了中含水期合理的注采压力系统,对油田目前的注采压力系统进行了评价,结果表明,注采井数比保持在1:1～1:1.15范围内,才能使注采压力系统在中含水开发期内保持动态平衡。在此阐述的研究方法,对于同类油田注采压力系统方面的研究和指导油田合理开发调整具有普遍推广的应用价值。Injection - production pressure system is an important part in the study of oilfield development, and adjustment in development strategy and establishment of technique policy boundary can achieve desired result only when injection - production pressure system is at a rational range. As for the contradiction that the existent injection -production pressure system established during the low water-cut period, based on the most flowing wells, can not meet the development demand after Shanshan oil field entered into medium water - cut period, a rational injection - production pressure system is studied and established on the basis of reservoir engineering and production engineering theories, starting with oil recovery and water injection system （from underground to borehole and surface）. Current injection - production pressure system of the oilfield is evaluated. It is concluded that if the injection - production pressure system can keep a dynamic balance during the medium water - cut period, the injector - producer ratio must be kept between 1 ： 1 and 1 ： 1.15. The method presented in this paper has a significant value for the study of injection - production pressure system in similar oilfields and can guide oilfield to carry out reasonable development adjustment.
