摘要

摘要: 层序地层学的发展及其在油气勘探开发中的应用,表现出以下新进展:1)地震沉积学是继地震地层学、层序地层学之后的又一门新的边缘交叉学科,但它是层序地层学和沉积学的发展而不是替代,体系域表征、90°相位转换、地层切片和分频解释是目前地震沉积学中的几种常用技术。2)层序地层学和地震沉积学在非构造圈闭精细勘探中得以广泛应用,用于预测与层序及体系域演化密切相关的油气藏。3)在湖盆沉积中,发现了与强制海退体系域相似的强制湖退体系域。4)海相碳酸盐岩的油气层序地层学研究得到了加强。5)高频层序地层学、天文地层学及其古海洋事件—生物礁储层形成演化相关关系研究的成果对于油气勘探发现具有重要意义。

Abstract: The advantage of sequence stratigraphy and its application in oil and gas exploration and deve-lopment appeared in these aspects as follows:(1)Seismic sedimentology is a new marginal and cross subject after seismic stratigraphy and sequence stratigraphy.It is a development of sequence stratigraphy and sedimentology,but not a substitute.There are several common techniques named characterization of systems tract,90° phase transformation,strata slice and the seismic spectral decomposition technology.(2)Application of sequence stratigraphy and seismic sedimentology in fine exploration of non-structural traps mainly shows prediction of oil and gas pools related with evolution of sequence and systems tract.(3)The forced regressived systems tract were discovered in lacustrine basin,similar to marine basin.(4)Study on oil and gas sequence stratigraphy in marine carbonate rocks were strengthened.(5)Results of high-frequency sequence stratigraphy,astronomical stratigraphy and palaeo-oceanography events as well as formation and evolution of biological reef reservoirs play an important roles in oil and gas exploration discovery.
