本文以东海西湖凹陷第三系为例，在孔隙度与深度现代测量数据拟合和建立的各类曲线方程基础上，筛选了砂岩、泥岩的最优压实数学模型。采用反演法和容积法、ＭｏｎｔｅＣａｒｌｏ法等，恢复计算了各研究层在各研究时期的泥岩压实水水头值、压实水量、砂岩容水量和水交替强度，勾划了沉积体系中泥岩压实水水头值系列图，重溯了沉积体系砂岩储集层中重力水渗流场及其演化过程。
Taking the Tertiary in the West Lake Sag, East China Sea as an example, the optimal compaction mathematical model of sandstone and mudstone was screened on the basis of various curve equations fitted and established by modern measured data of porosity and depth. Using the inversion method and the volumetric method, the MonteCarlo method and so on, the compaction water head value, compacted water volume, sandstone water holding capacity and water alternation intensity of each research layer in each research period were calculated and reclaimed. The mudstone pressure The series of real water header values recall the gravity water seepage field and its evolution in sedimentary sandstone reservoirs.
