【摘要】 地震成藏学是继地震地层学、地震沉积学和油气成藏学之后的一门新兴边缘交叉学科分支,是地球物理勘探技术及其成果与现代油气成藏理论相结合的产物.通过对其研究方法、内容及关键技术分析,认为直接利用地震解释成果(构造解释剖面、岩性反演剖面、烃检测剖面等)进行油气成藏分析是其研究的独特方法,它以精细地震构造解释技术、高精度地震岩性反演技术和稳定的地震弹性参数反演及烃类检测技术为手段,以现代油气成藏理论为指导,结合地震资料及解释成果,在油气潜力预测和勘探开发方面展示出良好的应用前景.以塔南凹陷t46井区为例,发现日产近万方的油气井,论证了高精度地震岩性反演技术在隐蔽油气藏(主要是岩性油气藏)预测中的重要价值.更多还原

【Abstract】 Seismic-petroleum accumulation science is a new branch of marginal intersection subject following seismic stratigraphy,seismic sedimentology and hydrocarbon accumulation,which is a combination of the geophysical exploration technology and modern hydrocarbon accumulation.Its research methods,contents and the key technologies are analyzed.Seismic-petroleum accumulation science is a kind of special research method,because it could easily analysis the process of hydrocarbon accumulation based on the results of seismic interpretation(such as structural interpretation sections,inversion profiles and hydrocarbon detection sections).The key methods for researching seismic-petroleum accumulation science contain fine structural seismic interpretation,high-precision seismic lithological inversion and stable seismic elastic parameter inversion and hydrocarbon detection technology.Application of the key techniques combined with seismic data and its results of interpretation,and modern hydrocarbon accumulation theory as a guidance,which shows the favorable prospect in oil and gas potential prediction and petroleum exploration and development.Application of seismic-petroleum accumulation science theory in forecasting subtle pool(especially lithologic reservoir),based on which a nearly ten thousands cubic meters oil-gas well is detected,has an important value revealed by an example of wellblock t46 in Tanan depression.更多还原
