水平井技术在洼38块东二段薄层稠油油藏开发中的应用

洼38块东二段属于层状边水普遍稠油油藏,由于地质条件复杂,油藏含油饱和度低,加之开发初期对储层认识不清,在开发方式上采用大段合采,油藏开发效果差.2006年以来,在精细地质研究的基础上,开展了利用水平井技术开发该油藏的可行性研究.现场实践表明,水平井技术可有效地改善油藏的开发效果,实现了区块年产油量稳定增长,油藏采收率得到大幅度提高,这对于同类油藏的开发具有较高的借鉴价值.

The application of using horizontal well technology to develop D2 heavy oil reservoirs with thin layer in Wa38 block

The type of D2 in Wa38 block is a general heavy oil reservoir with layered edge water.The reservoir development effect is poor because of low oil saturation,low degree reservoir understanding and wrong development mode and so on.Since 2006,the feasibility study of using horizontal well technology was conducted on the basis of fine geologic studies.The practical application shows that horizontal well technology can effectively improve the reservoir development effect,The amount of oil production has steadily...
