水平井综合录井地质导向系统及应用

通过理论研究与现场实践相结合,自主开发了水平井综合录井地质导向应用分析系统,该系统安装在综合录井仪上,利用综合录井资料结合MWD快速分析评价正钻井的实际情况。系统集地质导向、几何导向、井眼轨迹设计及控制、邻井防碰扫描等功能为一体,降低了因地质目标不确定而带来的钻探风险,降低了生产成本,为薄油层、厚油层顶部剩余油等复杂油气藏开采提供了技术支撑,有效控制了井眼轨迹在油层中钻进。现场应用表明,水平井综合录井地质导向分析系统具有广泛的研究价值和广阔的开发前景。

Geosteering System and Its Application in Compound Logging of Horizontal Wells

Based on the study on theory and field practice,the applied analysis system of geosteering in compound logging of horizontal wells was independently developed.This system is installed in the compound logging instrument.It can be used to quickly analyze the actual situation of the drilling well by using the compound logging material.The system integrates the design and control of well track,the geometry guidance,the geosteering,the scanning of against bump between the adjoining wells,and so on.And,the system reduces the drilling risk because of the indefinite geologic goal,and the production cost.Also,the system provides the technical support for the exploitation of the complex reservoir,effectively controls the drilling of the well hole in the oil layer.The application result indicates that the analysis system of geosteering in compound logging of horizontal well has the extensive researching value and developing prospect.
