简要介绍了地层定量模拟的基本思路和方法；阐述了模型的主要输入参数、约束条件和模拟过程；最后列举了３个模拟实例。地层定量模拟是沉积盆地模拟的重要组成部分。它可用于分析盆地内沉积体系和沉积相带的形成规律、地层展布型式以及沉积相序的发育规律等与海平面变化和盆地沉降之间的关系，预测盆地内油气藏生储盖组合及有利的含油气相带等，是近年来新兴的一个研究方向
The basic idea and method of stratum quantitative simulation are briefly introduced. The main input parameters, constraints and simulation process of the model are expounded. Finally, three simulation examples are given. Stratum quantitative simulation is an important part of sedimentary basin simulation. It can be used to analyze the formation of sedimentary systems and sedimentary facies in the basin, the distribution patterns of strata and the developmental rules of sedimentary facies, and the relationship between sea level changes and basin subsidence. Favorable hydrocarbon-bearing belts, etc., is a newly emerging research direction in recent years
