Huimin Brush Structural System and Its Influence on Sedimentation and Reservoir Formation

Brush structural system, being the production of rotational-shear stress field in different levels which controls both various sedimentary systems and petroleum accumulation and distribution is an important structural system in Huimin sag. It is meaningful for exploration practice of oil reservoirs to study the formation, evolution, characteristics and spatial distribution of Linshang brush fracture in detail, analyze the sedimentary system characteristics of Shanghe sand body and the control of Linshang brush fault to the Shanghe sedimentary system and then discuss influences of brush structural system on petroleum accumulation and distribution.
