Individual Drilling Bit Design and Optimization in Mahu Area
There are three sets of gravels in Mahu region.The gravels formation is characterized by high heterogeneity,high abrasiveness and poor drillability.It is so difficult to optimize bit that restrict seriously the overall exploration and development process.The compressive strength,internal friction angle,and drillability of the formation are tested to check the rock mechanical characteristic profile established by logging data.The individual bit design is carried out by the 3D simulation technology.A new PDC bit type is designed to form the drill bit series for Mahu area.Single PDC bit increases 90%of the drilling footage.The trip average footage is improved 3.45 times,the horizontal section average penetration increased 34.8%.The technical achievements have greatly improved economic development benefits of Mahu region by improving drilling speed and saving drilling costs.
