摘　　要：渤海P油田断裂系统复杂,断层封闭性是油田安全高效开发的基础。利用滑动趋势和膨胀趋势定性评价断层剪切活化和张性活化趋势,采用断层泥比率(SGR)量化断层带内泥质含量,利用不同区块断层压差和SGR关系表征断层侧向封闭能力,从而实现断层封闭性定量评价。结果表明,研究区内断层均处于稳定状态,但部分断层侧向封闭性低,而走滑断层存在侧向不封堵现象。The fault system of Bohai L Oilfield is complex,and fault sealing is the foundation for safe and efficient development.This article qualitatively evaluates the shear activation and tensile activation of faults using Sliding Trends and Expansion Trends,quantifies the mud content within the fault zone using the Fault Shale Gouge Ratio(SGR),and characterizes the lateral sealing ability of faults using the relationship between fault pressure difference and SGR in different blocks,thereby achieving quantitative evaluation of fault sealing.The results indicate that all faults in the study area are in a stable state,but some faults have low lateral sealing,while strike slip faults exhibit lateral non sealing phenomena.
