针对特殊需要设计专用钻头

随着钻井区域扩大,现有钻头已不能满足某些特殊的作业要求,现场希望开发能适应具体情况的新钻头。国外钻头公司采用以仿真技术为核心的设计方法设计专用钻头,既为公司创造了利润,又为钻井队节约了成本。从现场资料和试验资料积累,钻头-岩石-下部钻柱系统计算机仿真,以及钻头优选和优化设计软件开发等方面阐述了专用钻头设计技术的要点。

Specialized drill bit design for special use

With the enlarged drilling range,the current drill bit can not meet the special operation demand. The new drill bit for specific purpose needs to be developed. In foreign drill bit companies,the design method with simulation technology as core is used to design the specialized drill bit. It cannot only create benefit for the companies,but also save cost for the drilling team. The key points of designing specialized drill bit are elaborated from the accumulation of field data and test data,the computer simulation of drill bit-rock-lower drill string system and drill bit selection and optimizing design software.
