大港油田“一趟钻”轨迹控制技术

“One trip drilling”trajectory control technical In dagang oil field

随着大港油田公司“降本增效”的不断深入,迫切需要钻井提速,缩短钻井周期节约成本,针对定向作业,根据大港油区不同井型、剖面及井身结构、层系岩性特点,通过优化钻具组合、推广螺杆钻具改型、完善钻井参数配套,提高“一趟钻”定向井轨迹控制技术,从而实现安全快速钻井,提高经济效益,在大港油田具有良好的应用前景。

With the continuous developing of"cost reduction and efficiency increase"of Dagang Oilfield Company,there is an urgent need to speed up drilling,shorten the drilling period and save costs.For directional operations,according to different well types,profiles,wellbore structures,and formation lithology characteristics in Dagang Oil Region,safe and fast drilling can be achieved by optimizing the drilling tool assembly,promoting the screw drill tool modification,improving the drilling parameter matching,and improving the"one trip drilling"directional well trajectory control technology,It has a good application prospect in Dagang Oilfield to achieve safe and fast drilling and improve economic benefits.
