地质油藏随钻技术在渤海水平分支井钻进中的应用

将随钻测井技术与随钻综合录井技术结合形成的地质油藏随钻技术 ,能够更好地控制井眼轨迹 ,确保水平分支井井眼顺利钻入目的层并按设计要求穿行一定长度的地层 ,提高油井产能。在渤海海域水平分支井的钻进中 ,这一综合技术正在水平分支井的钻前准备、各井段钻进及地质导向等方面发挥着重要的作用 ,并已在秦皇岛 32 6、绥中 36 1等油田水平分支井的钻进中成功应用 ,使主井眼段和分支井段无一偏离目的层 ,使油层段电阻率及孔隙度均达到开发设计标准

Applications of geological reservoir technique while drilling of horizontal multilateral well in Bohai sea

Geological reservoir technique while drilling is formed by integrating the logging while drilling and compound logging while drilling, by which the well path can be controlled much better to ensure the horizontal interval entering the target and penetrating a certain length in the reservoir according to design for improving the productivity of the horizontal multilateral well. In the drilling of multilateral well in Bohai sea, this integrated drilling technique played important role in pre-drilling preparation, drilling and geo-steering. It has been utilized successfully in drilling lateral in QHD 32-6 and SZ 36-1 oil fields, without any main holes and laterals getting off the target, making the resistance and porosity in the reservoir meet the standards of development design.
