断层既可作为油气运移的通道 ,又可对油气形成封堵。在砂岩含量丰富、靠近油源的复杂断块区 ,断层封堵区域的分析与界定使我们能直接划分由封堵形成的油气藏范围。这类区域以断层两侧岩性配置封堵模式为主。分析岩性对接配置的理想方法是根据断层两侧钻井资料确定断层面的岩性对接 ,实际上常因钻井资料少而使此法难以施行。在分析、比较多种测井约束地震反演方法后 ,我们找到一种反演结果可靠的地质统计反演方法 ,依此研究断层面岩性对接关系。将其应用到民丰断裂带封堵分析研究中 ,反演出了较理想的岩性剖面
The fault can act as a passage for hydrocarbon migration as well as block oil and gas formation. The analysis and definition of the fault sealing area in the complicated fault block area with abundant sandstone and close to the oil source enable us to directly divide the reservoir range formed by plugging. This kind of area is dominated by the lithology configuration and sealing mode on both sides of the fault. The ideal method for analyzing the configuration of the lithology docking is to determine the lithology docking of the fault plane based on the drilling data on both sides of the fault. In practice, this method is often difficult to implement due to the small amount of drilling data. After analyzing and comparing various well logging constrained seismic inversion methods, we find a reliable inversion method of geostatistics, and study the relationship between fault lithology and docking. Applying it to the sealing analysis of Minfeng fault zone, the ideal lithologic profile
