八面河地区滩坝砂储层研究及开发实践--以面4－面14区沙四1砂组为例

摘要

There is a large range of beach-bar sandstone reservoir in Bamianhe Oilfield with a large scale of reserves among which untouched reserves of thin oil suitable for water -flooding and Class 1 heavy oil are majorly distributed in 1st sand group of Sha-4 member of Mian 4-14 at the main tectonic belt .Based on Static and dynamic data ,in‐terpretation standard is reenacted to interpret the reservoir again and estimate its oiliness and physical property . Three years of development practice in the new district proves that early water -flooding ,proper shortening of well spacing and beforehand filling modification are suitable to such a reservoir .%八面河油田滩坝砂储层分布范围较广，未动用储量达两千余万吨，储量规模大。其中适合注水开发的稀油和普通稠油Ⅰ类油藏未动用储量主要分布在主体构造带的面4－面14区沙四段1砂组。此次主要通过岩芯、生产动态等静动态资料，重新制定解释标准，对储层进行二次解释。并结合测井资料归一化成果，对储层含油性、物性特征做出评价。进而综合开发方式及配套工艺优化组合研究成果，优选区域开展评价和新区产能建设。通过近三年的新区产建实践，证实先期注水开发、适当缩小井距的开发方式及预充填改造等配套工艺是适合该区域储层，能够满足其储层开发需要。
