莺歌海盆地是一个发育于南海北部大陆架的新生代强超压盆地。通过对地层温度和有机质成熟度的系统测试及其与模拟结果的对比、泥岩中残余可溶有机质含量和组成的对比分析及粘土矿物转化和砂岩孔隙度分布的系统分析 ,证明超压流体流动可以产生强烈的油气成藏效应 :1超压流体流动
Yinggehai Basin is a Cenozoic overpressure basin developed in the northern continental shelf of the South China Sea. Based on systematic tests of formation temperature and organic matter maturity and their comparison with simulation results, the comparative analysis of the content and composition of residual soluble organic matter in mudstone and the systematic analysis of clay mineral transformation and sandstone porosity distribution show that overpressure fluid can flow Produce a strong hydrocarbon accumulation effect: 1 overpressure fluid flow
