摘要:
轴向重力流沉积是一种重要的深水储层，其形成的岩性油气藏也是目前莺歌海盆地重点勘探领域。通过钻井、测井、地震和区域地质等资料的综合研究，分析莺歌海盆地中新统轴向重力流沉积特征和演化规律，探讨轴向重力流岩性油气藏的成藏条件和控制因素。结果表明，中新统储层为重力流沉积成因的厚层细砂岩，主水道和朵叶复合体是重力流沉积有利的沉积微相；中新世海南物源供给充足、断裂坡折带发育以及盆地轴向负向地形是该区形成轴向重力流沉积的宏观地质条件，在中新世各个时期形成了一系列沿盆地轴向分布、具有前积反射结构特征的轴向重力流沉积。研究区中新统轴向重力流储层厚度大、沉积规模广、临近烃源岩、构造脊微裂隙发育、圈闭保存好，具备优越的岩性油气藏成藏条件，是盆地下一步勘探的重要领域。
Abstract:Longitudinal gravity flow deposits, as a kind of important deep-water reservoir, are critical to the exploration of natural gas in the Yinggehai Basin for the time being. Based on the integrated drilling, logging, seismic and regional geological data, the depositional characteristics and evolutionary history of the Miocene longitudinal gravity flow in the Basin is studied by the authors. Discussed are also the hydrocarbon accumulation conditions and controlling factors of the lithologic reservoirs of gravity flow. Facts show that the Miocene reservoir is a kind of thick massive fine sandstones favorably deposited in some distributary channels and lobes in deep water. In the time of Miocene, a great amount of sediments was supplied by the Hainan uplift and surrounding fault slope breaks. They filled the longitudinal depressions as gravity flow deposits with favorable forming conditions of lithologic reservoirs characterized by great thickness, large area and proximity to source rocks. Structural fissures are well developed. Therefore, excellent trap conditions are available in the area and they should be the future exploration targets in the Yinggehai Basin.
