基于MATLAB的随钻方位伽马数据图像的生成与处理

Generation and Processing of Azimuthal Gamma Data Imaging with Drilling Based on MATLAB

通过处理随钻方位伽马测井数据得到的测井图像,可以有效地控制井下钻头轨迹,提高钻头钻遇率,对大斜度井、水平井勘探开发具有十分重要作用。通过Matlab将得到的不同深度下各扇区伽马数据进行插值、数据整合、色谱选定、色度标定和图像插值滤波处理,实现随钻测井图像生成和处理,最后经调试使生成图像能够清晰反映地层特征,满足勘探开发需要。

By processing the logging images obtained from the drilling directional gamma logging data, the trajectory of the downhole bit can be effectively controlled, and the drill bit drilling rate can be improved, which plays an important role in the exploration and development of high-angle wells and horizontal wells. Through the Matlab, the gamma data of each sector at different depths is interpolated, data integrated, chromatographically selected, chroma calibration and image interpolation filtering are processed to realize the generation and processing of the logging while drilling image. Finally, the generated image can be debugged. Clearly reflect the characteristics of the stratum to meet the needs of exploration and development.
