PDC钻头在鄂北工区的应用

The Application of PDC Drills in North Hubei Working Area

针对鄂北工区的地层特点和现场掌握的PDC钻头现场使用资料,按照工区不同区域,将钻头的选型、改进、磨损分析等因素结合起来,分井段优选出较符合该区地层的PDC钻头型号,并提出PDC钻头在鄂北使用时选型的依据。

In the light of the stratigraphic characteristics of North Hubei Working Area and the data about the field application of PDC drills got in the field, and combining some factors such as the type selection, improvement and dullness analysis of the drills based on different zones of the working area, this paper makes the selective preference of the type of PDC drills fitting in with the stratum based on intervals, and puts forward some foundations for the type selection of PDC drills used in North Hubei Working Area.
