【摘要】 以滨立海盆地D区块为例,综合薄片,测井,岩心,地震等资料,对石炭系A段地层展开地震相-沉积相分析。根据地震波反射内部结构和外部形态,在研究区识别出七种不同的地震相类型。在钻测井资料约束下,将地震相转化为沉积相。结合岩心薄片资料分析认为,东北部以发育局限台地内局部海滩相为主,而局部海滩经后期溶蚀作用,恰好是油气的有利储集相带。更多还原

【Abstract】 Do research for the seismic facies- sedimentary facies analysis based on thin section,logging,core and seismic data,taking A group of the D district in Pre- Caspian basin as an example. Based on the seismic reflection,seven types of seismic facies were mainly recognized. Combined with the thin section data,northeast of the study area was mainly developed weak continuous low amplitude seismic facie on behalf of the restrictied bank.The restrictied bank by late dissolution happens to be favorable reservoir facies of oil and gas.更多还原
