摘要
克拉玛依九区稠油油藏具有整装、构造简单、开发时间长、经历蒸汽吞吐、蒸汽驱等多个开发过程。应用数值模拟方法对其开发历史进行精细数值模拟,在对储量动用状况、剩余油分布规律和影响因素分析的基础上,利用修正后的预测模型进行多井组、多种开发方式、多注采参数优化调整及预测,确定了研究区在蒸汽驱阶段合理的间歇汽驱周期、注汽速度及调整时机等。研究表明,在蒸汽吞吐之后采用间歇汽驱、变速汽驱、热水驱相组合的开发方式的开发指标优于其它方案。开发方式在现场是可行的,优化研究方法可供同类油田借鉴。
The heavy oil pool in District No.9 of Karamay oilfield is characterized by self-contained type,simple structure, long development history,steam huff and puff drive and steam drive.Numerical simulation method is adopted to sim- ulate the fine development history.On the basis of analyzing the reserve mobilization,and the distribution and effective factors of residual oil,forecasting models are revised to per- form the optimization and forecasting of the multiply well group,multiform development modes and multiply injection and recovery parameters;hence define the rational intermit- tent steam drive cycle,steam injection velocity and adjust- ment time.Results suggest that after steam huff and puff, the development index of the development mode integrating intermittent steam drive,speed-variable steam drive and hot water flooding is superior to others.On-site practice shows that the development mode presented is feasible and can be used for reference for other same kind of oilfields.
