黄骅含油气裂谷盆地沉积体系渗流场形成演化的重溯

Based on the characteristics of geologic structure at the region of interest, the types of the aqueous and hydraulic pressure system and the hydrogeological stages had been differentiated. Synchronously, the analog calculation on the extruded water head of ruffite and the intensity of water alternate in every stage of Tertiary had been performed in Huanghua rift basin. The study not only reconstructed the history of evolution on the head and the seepage and hydrochemical field in Huanghua rift basin, but also revealed the brine of the gas-field of upper Triassic, the seepage and hydrochemical field, and their zoning in Chuanxi sag. And then the research approach was obtained on evolution of the seepage field in sedimentary basin. The research also expanded the time and space sale of hydrogeological study and offered an example of the evolution of deep water and its system of cognition. There are highly significance for actual use and prediction and evaluation on oil/gas migration and accumulation in the region.

建立盆地第三系沉积体系含水系统层序和水文地质期期序，压实数学模型，砂泥岩恢复厚度计算模型和水文地质概念模型，拟用反演或正演或耦合运算，求解各层在各研究时期压实水水量水头，渗入水入渗量，水交替强度，沉积水和渗入水、压实水和重力水的循环转化和渗流场的形成演化机理。发展和创新深部流体动力学理论，对油气运聚成藏研究有指示意义。
