摘要

水沙仿真技术是运用成熟的流体力学、泥沙运动学方程和经验公式来控制其运动

并借助计算机技术定量地描述其动力地质过程及结果的一种动态模拟模型。应用水沙仿真技术对X区块九佛堂组上段下部模拟结果表明

该区物源区位于东南盆地边缘

沉积呈扇状向西北扩散

古水流主要为290°～340°之间

与沉积物扩散方向基本一致。模拟预测的砂体厚度与钻井揭示的厚度吻合率达80%.

Abstract

Fluid-sediment simulation technique is a kind of dynamic simulation model in which hydrodynamic and kinetic formulars and equations are used to control and describe the transportation and deposition processes of sediments with the help of computer. This technique isused in the simulation of the lower part of the upper member of the Jiufutang Formation in Xregion. The results suggest that the provenance of the sediments is in the margin of the basinsoutheast to the region;the sediments shaped as a fan spreading northwestward. The paleocurrents there are between 29°～34°

which basically coincide with the spreading direction ofthe sediments

80% of the predicted thicknesses of the sand bodied coincide with that provedby drilling.
