【摘要】：输导体系控制红河油田油气运聚成藏,为了更为有效地研究鄂尔多斯盆地输导体系,基于地质、录井、测井及地震解释,系统分析红河油田延长组输导体系"断-砂"组合的匹配性。利用泥岩涂抹因子(SGR)及断层紧闭指数(I_(FT))定量分析研究区断层输导性能,断层间不同的封堵特征体现了断层输导差异性。采用有效空间系数(C_m)及砂体输导系数(K_s),定量厘定主力输导层并分析其输导性能,砂体输导系数与油气显示的关系研究表明,Ks2的砂体具有较好的输导性能。结合成藏关键时期及现今的油藏剖面解析,发现油气运聚区域与现今油藏分布基本吻合。研究认为,现今鄂尔多斯盆地镇泾区块红河油田储层在低孔低渗的背景下,成藏关键时期的"断-砂"输导体系是油气运聚的主要通道,部分区域存在油气沿裂缝垂向运移。
[Abstract]:In order to study the migration system of Ordos Basin more effectively, the system is based on geology, logging, logging and seismic interpretation. The matching of fault-sand combination in Yanchang formation of Honghe Oilfield is analyzed systematically. Using mudstone smear factor (SGR) and fault tightness index I\ {\}\%\ In this paper, the effective space coefficient (CIM) and the sand body transport coefficient are used to determine the main transport layer quantitatively and analyze its transport performance. The research on the relationship between the sand body transport coefficient and the oil and gas display shows that the sand body of KS2 has better transport performance. Combined with the analysis of reservoir profile during the key period of reservoir formation and present time, it is found that the distribution of oil and gas migration and accumulation area is basically consistent with that of present oil and gas reservoir. It is considered that under the background of low porosity and low permeability in Honghe Oilfield in Zhenjing Block, Ordos Basin, the "fault-sand" transportation system in the key stage of reservoir formation is the main channel for oil and gas migration and accumulation, and there is vertical migration of oil and gas along fractures in some regions.
