南堡凹陷断裂特征及对油气藏的控制作用

南堡凹陷位于渤海湾盆地黄骅拗陷北部,受多期构造运动影响,断裂发育,新近纪晚期在东西向弱挤压背景下构造发生正反转,形成特殊的正向负花状构造样式。本文在区域地质分析的基础上,应用时间和相干体切片、曲率体并结合钻井、测井及开发动态资料识别技术对南堡凹陷的断裂进行了识别,总结了断裂剖面组合样式及平面展布特征,同时明确了断裂活动特征及其对油源、储层、圈闭等的控制作用。

Fault characteristics in Nanpu sag and their control of reservoirs

Nanpu sag is located in the north of Huanghua Depression,Bohai Bay Basin.Influenced by multi-phase tectonic movements,the faults are well developed.In late Neogene,due to the structural reversion under EW direction weak compressive force in Napu sag,specific negative flower structure styles were formed.The faults are indentified by means of time and coherence cube slices,as well as curvature data,dynamic development data,logging well data.The fault styles in profile and in plane are summarized in this artic...
