云南耿马盆地中新统地震相研究与油气远景分析

本文在对耿马盆地进行地震层序划分的基础上，重点研究盆地中新统的地震相类型和展布，结合地质、地球物理等多种参数，进行了沉积相解释，认为该盆地发育有半深湖、滨浅湖、扇三角洲、河流三角洲、近岸水下扇及含煤沼泽等相带，并探讨了沉积相与油气产出的关系，认为耿马盆地有一定的油气勘探远景。

STUDY ON SEISMIC FACIES AND OIL GAS PROSPECT OF MIOCENE IN GENGMA BASIN,YUNNAN

Based on the subdivision of seismic sequences of Gengma basin,it is mainly studied the types and distribution of the seismic facies of Miocene in this paper.The sedimentary facies of the basin are deciphered by means of analysis on the seismic facies and parameters of geology and geophysics.Some sedimentary facies,such as:moderate depth lake,coastal shallow lake,fan delta,fluvial delta,near coastal subaquatic fan and coal swamp are desctibed.The relation between sedimentary facies and oil gas occurrence are also discussed.It is pointed out that there may be a certain oil gas exploration prospect area in Gengma basin.
