四川盆地涪陵焦石坝地区五峰—龙马溪组低序级断层识别技术及应用效果
Low-grade fault recognition technology and its application in Wufeng-Longmaxi formations in Jiaoshiba area, Fuling, Sichuan Basin
摘要
Abstract
The development of shale gas in the Fuling area of Sichuan Basin has achieved remarkable results. However, in the practice of shale gas development the phenomenon of drilling mud loss is frequent, and low-produc-tivity and inefficient wells occur from time to time, which is considered to be closely related to low-grade faults. The North American shale gas development zone has a simple structure, while the Fuling Jiaoshiba block is superimposed by multi-stage tectonic movements with strong deformation and complicated faults. The conventional low-grade fault recognition was mainly based on drilling and logging data. A new method combining well data with seismic data uses both dynamic and static aspects. It was based on the comprehensive utilization of 3D seismic, drilling, well logging and gas test data. Fine horizon calibration, horizontal slice, variance body, curvature and other methods were applied to identify low-grade faults, which provided an important geological basis for the deployment and adjust-ment of horizontal wells, drilling design and the optimization of fracturing parameters.关键词
