渤海油田小井眼完井可行性研究

The Feasibility Study of Slim Hole Completion in Bohai Oilfield

随着近期油价的持续低迷,渤海完井成本的控制也越来越严格。本文着眼于小井眼技术,从完井层面分别论证渤海地区优化后的小井眼井代替常规经验井身结构的可行性。得出了射孔枪尺寸对油井产能的影响较小;满足压裂充填要求,可实现压裂充填6层以内分层配注;分采管柱满足生产排量要求;套管内测试工具、防砂工具和洗井工具需特殊设计;对单井产能影响很小;小井眼完井技术可以在渤海地区逐步推广等结论。

With the recent oil prices continued to slump, the cost of well completion is becoming more and more strict in Bohai. This article focuses on the technology of the slim hole It is prove respectively that feasibility of that optimization of slim hole which conventional experience well structure in Bohai area from completion. It is concluded that the size of perforating gun has little effect on the productivity of oil well and Meet the requirements of fracturing filling. It can be achieved that Stratified injection in 6 layers of fracturing and it＇s also meet the production requirements of discharge pipe. Casing test tools, sand control tools and well flushing tools need to be specially designed. The influence of single well productivity is very small： well completion technology can be popularized in Bohai
