浅薄层稠油油藏高轮次蒸汽吞吐后剩余油分布及潜力评价
|
摘要
井楼油田中区稠油油藏具有"浅、薄、稠、散及油水界面参差不齐"的特点,蒸汽吞吐开发已40多年,目前,已经进入高轮次蒸汽吞吐后期,生产效果、经济效益变差。要实现稠油可持续发展,关键是要研究高轮次蒸汽吞吐后剩余油分布特征。立足于丰富动态资料,通过油藏动态分析与数值模拟相结合方法,研究高轮次蒸汽吞吐后剩余油分布特征,总结了井间剩余油分布模式,并针对剩余油分布潜力进行分类型评价,为井楼中区进一步提高采收率提供了技术支撑。
Heavy oil reservoirs in the middle area of Jinglou Oilfield are characterized by "shallow,thin,thick,scattered and uneven oil-water interface".Steam huff and puff has been developed for more than 40 years. At present,it has entered the later stage of high-cycle steam huff and puff,and its production effect and economic benefit have become worse.In order to realize the sustainable development of heavy oil,the key is to study the distribution characteristics of remaining oil after high cycle steam stimulation.In order to realize the sustainable development of heavy oil,the key is to study the distribution characteristics of remaining oil after high cycle steam stimulation.The distribution pattern of residual oil between wells is summarized,and the distribution potential of residual oil is classified and evaluated.It provides technical support for further enhancing oil recovery in the middle part of the well building.
