【摘要】 本文以国内少见的发育在主动大陆边缘的特殊盆地类型海沟-斜坡盆地作为研究对象,通过建立井震结合的不同沉积体系的地质-地球物理识别模板,用二维地震资料对研究区目的层的沉积体系进行了解析。结果显示,研究区发育窄的滨浅海、小规模的三角洲、浊积扇、下切谷、半深海陆坡和半深海平原等沉积体系。滨浅海、三角洲和浊积扇沉积体系发育的砂体是主要的储集体。海沟-斜坡盆地的规模较小,以生气为主,可能形成中小型断块油气藏。更多还原

【Abstract】 The sedimentary systems are explored on the basis of 2D seismic data for the target strata in one block in the Arakan Coast basin,Myanmar developed in the trench-slope basins along the active continental margin.The results of research in this study have disclosed that the sedimentary stsyems in the study area dominantly consist of the littoral-shallow sea,delta,turbidite fan,incised valley,bathyal continental slope and bathyal plain sedimentary systems.The reservoir rocks are mainly developed in the littoral-shallow sea,delta and turbidite fan sedimentary systems.The small-sized trench-slope basins may be host to the medium-or small-sized block oil-gas pools dominated by natural gas.更多还原
