苏浙皖海相盆地作为我国南方海相油气勘查的重点盆地之一,具有古生代和早中生代海相沉积的漫长历史,发育巨厚的海相建造,形成多套烃源岩系,具有良好的生油物质基础。然而,印支运动之后,海相沉积体制解体,盆地原型及其沉积建造受到严重构造改造,从而成为残留盆地。残留盆地具有复杂的油气系统,因此,苏浙皖海相油气勘探应根据其残留盆地的特点,正确地选择和确定勘探目标与对象。 As one of the key basins in marine oil and gas exploration in South China, the marine facies of the Jiangsu, Zhejiang and Anhui provinces have a long history of Paleozoic and Early Mesozoic marine sediments. They have developed a large number of marine facies and formed several sets of source rock series with good Raw material base. However, after the Indo-Chinese Movement, the marine sedimentary system was disintegrated, and the prototype of the basin and its sedimentary construction were severely remolded so that it became a residual basin. Since the residual basins have complex petroleum systems, the exploration targets and targets should be correctly selected and determined according to the characteristics of their residual basins.
