中文摘要:

研制的随钻近钻头工具能够有效地克服常规随钻测量系统测点远的不足，非常适合于在复杂地层或薄油层的情况下使用，具有现场组装方便、作业成本低的优势。其中近钻头方位伽马测量系统是其实现地质导向控制的核心。详细介绍了近钻头方位伽马测量系统的两大重要模块：扇区测量模块及伽马计数处理模块。现场实验证明该系统能够快速指示出工具穿越层位时的方向，满足现场作业要求，具有一定的市场价值。

英文摘要:

The near-drilling tool can effectively overcome the shortcomings of the conventional measurement while drilling system, which is very suitable for use in complex formations or thin reservoirs, and has the advantages of convenient field assembly and low operating cost. Near-bit azimuth gamma measurement system is the core of its geological steering control. In this paper, two important modules of near-bit azimuth gamma ray measurement system are introduced in detail: sector measurement module and gamma counting processing module. Field experiments show that the system can quickly indicate the direction of the tool crossing the horizon, meet the requirements of field operation, and has a certain market value.
