查询词典 well drilling

It not only needs the drilling crew to carry out basic yielding task but also other logistics and assistance departments such as the well site sureying drilling design scene perambulating moving and riging up matarial providing cementing well logging and equipent maintenance.

摘要石油钻井工程是进行石油天然气资源勘探开发的主要工程，被誉为&石油工业的火车头&。

Self-elevating drilling platforms play an important role in the reconnoitering and the exploitation of offshore oil fields. But with the advancement of offshore oil industry, the earlier self-elevating drilling platform cant function well to satisfy the demands of the development of offshore oil reconnoitering and exploitation. They should be upgraded to be able to function as well as possible.

自升式钻井平台在海洋石油勘探开发中发挥着积极的作用，但随着海洋石油工业的发展及海洋勘探技术的不断提高，早期设计建造的自升式钻井平台在许多方面不能适应形势发展的需要，需要进行升级改造，以提高施工能力。

Drilling an oil or gas well within a developed field for which an approved land use plan or any environmental document prepared pursuant to NEPA analyzed such drilling as a reasonably foreseeable activity, so long as such plan or document was approved within 5 years prior to the date of spudding the well.

钻探油井或远低于发达领域的核准土地使用计划或任何环境准备的文件根据国家环保局气体分析作为一个合理的可预见的活动，如钻井，只要这样的计划或文件被批准在5年之前对钻井日期。

So in order to improve ROP, the VTK vertical drilling technology of Baker Hughes was introduced. VTK is a kind of closed loop, automatic, and vertical drilling technology, made up of closedloop rotary steering drilling system AUTOTRAK, highperformance X-TREME motor and reliable MWD. It is able to return the well path back to vertical by adopting downhole microprocessors to analyze the measured deviation data and determine the proper force necessary for decreasing the deviation angle to guide the steering rib at the highside to reliably stick out against the upper wellbore.

为提高机械钻速，引进贝克休斯的VTK垂直钻井技术，它是由AUTOTRAK、高性能X-TREME马达、可靠的MWD三种技术开发出来的一种闭环自动垂直钻井技术，能够根据井眼的偏斜，经井下微处理器分析判断，使导向稳定地靠近井眼高边方向导向肋板伸出顶向上井壁，这样使钻头产生合理的降斜力，从而使井眼回到垂直轨道上来。
