摘要
经过近40年的开发,胜坨油田坨28块已进入特高含水期。由于油层非均质性严重、注采井网完善程度低、层间干扰等原因,造成油藏压力不均衡,制约了油水井生产潜力的发挥。针对这一现状,利用数值模拟技术,对该油藏合理压力水平进行了研究,并确立了相关参数的界限值,为改善特高含水期油田开发效果提供了理论依据。
After 40 years' development, Tuo28 block of Shengtuo oilfield has entered extra high water cut period. Severe heterogeneity of oil-bearing formations, low perfecting degree of well pattern and interlayer interference cause the non-equilibrium of reservoir pressure and restrict the production potential of oil and water wells. Reasonable reservoir pressure level is studied by numerical simulation, and the limit value of correlative parameter is determined, which provides theoretical foundation for improving the development results of the oilfield in extra high water cut period.
