地质工程一体化录井综合导向模式设计与应用

Design and application of comprehensive guidance mode for geology-engineering integration mud logging

传统水平井现场作业中钻井、随钻定向、录井等多专业间数据共享程度低、沟通不畅、协作能力差,不能完全满足复杂水平井施工需求。为此,构建了由“地质导向+随钻定向+钻井风险评价+录井技术+远程信息化”组成的地质工程一体化录井综合导向模式,以导向为核心,地质与工程换位思考、综合分析,开发了地质工程一体化录井综合导向平台,促进不同地点、不同时间、不同专业人员间信息共享,协同决策。水平井施工过程中,应用该综合导向模式,以提高储层钻遇率为原则,兼顾工程轨迹可行性、安全性,有效降低了水平井施工风险,同时实现了“地质甜点”和“工程甜点”双目标,为提高水平井钻井时效和开发效果提供了有力技术保障。

The low data sharing,ineffective communication,and poor collaboration among multiple disciplines such as well drilling,orientation with drilling and mud logging in traditional horizontal well field operation failed to fully meet the needs of complex horizontal well construction.To this end,a comprehensive guidance mode for geology-engineering integration mud logging is constructed,which consists of geosteering,orientation with drilling,drilling risk assessment,mud logging technology,and remote informatization.With guidance as the core,empathizing and comprehensively analyzing geology and engineering,a comprehensive guidance platform for mud logging with geology-engineering integration has been developed to promote information sharing and collaborative decision-making among different professionals at different locations and different times.It is applied in horizontal well construction to improve the drilling rate of reservoir with consideration of feasibility and safety of engineering trajectory,effectively reducing the construction risk of horizontal wells.Meanwhile,the dual goals of geological sweet spot and engineering sweet spot are achieved,providing a strong technical guarantee for drilling efficiency and development effect of horizontal wells.
