STG盆地碳酸盐岩潜山储层特征及成藏模式
Reservoir Characteristics and Hydrocarbon Accumulation Mode for Carbonate Buried Hill Reservoirs in STG Basin
摘要
Abstract
In order to solve problems in STG basin including unclear distribution of carbonate buried hill,multiple reservoir space types and unclear understanding of hydrocarbon accumulation pattern,seismic stratigraphy and res-ervoir geology method are combined,3D seismic data,core and slice observation and logging lithology method are used for interpretation. The results show that carbonate buried hills in the research area are mainly developed in the northwest of the basin,where there are five types of reservoir rocks including limestone,bioaccumulated limestone, dolomitic limestone,argillaceous limestone and lime mudstone and reservoirs have fracture-corrosion hole composite reservoir space. Based on this research and exploration experience,hydrocarbon accumulation mode is built for bur-ied hills in the research area,which provides guidance for exploration of buried hills in this area.关键词
