摘要： 海上油气开发一直以高成本、高风险著称,做好成本控制是低原油价格时代对渤海钻完井提出的极大挑战,尤其是小项目零散调整井作业。为此,在充分认识调整井作业难点、深入分析钻井成本组成的基础上,渤海油田提出利用停产井侧钻新井位,最大化利用老井眼井段,通过油藏工程的可行性论证,优化设计靶点、充分探边、释放剩余产能,钻完井工程一路优化定向井轨迹与井身结构,采用钻修机设备、引入国产旋转导向及随钻测井系统,在保证能够实现作业的前提下,充分降低作业成本。最终圆满完成轨迹导向和测井任务,有效实现侧钻水平井着陆。侧钻井整体降本14.7%,产量达到钻前配产的2.2倍,效果显著。

Abstract: International crude oil prices continued to decline in 2015, approaching MYM30.0 per barrel. This seriously impacts the domestic oil and gas development upstream industry. Offshore oil and gas development known for high cost, high risk, low oil prices in the doldrums makes a great challenge to Bohai drilling and completion, especially for small projects with scattered adjustment wells. On the basis of studying the difficulties and analyzing the cost, through the side drilling and using of domestic rotary steering and longing tools, Bohai oil field has achieved the horizontal well. The overall cost is reduced by 14.7%, and the production reaches 2.2 times the proration before drilling. The effect is significant.
