碳酸盐台地沉积过程的计算机模拟

用定量的计算方法来模拟碳酸盐台地的二维地层空间，可以预测储层分布，调整井和地震资料的解释，在盆地前期勘探资料不足的情况下，检验勘探方案及估计地层的基本控制因素。该文首先对模拟的数学方法作了详尽的推导及合理假设，提出了碳酸盐台地模拟的主控因素，并将这些因素与数学方程对应起来；其次，对模拟的各主控因素分别加以讨论，明确它们在地层模拟中的地位，检验其对地层几何形态及岩性控制的作用；最后，通过不同参数下的模拟实例，进一步证明其正确性。同时在模拟出的图形中，可以清晰地看到层序地层学中提出的一些地层要素。

COMPUTER MODELING THE SEDIMENTATION OF CARBONATE PLATFORMS

This paper introduces a quantitative method to simulate the sedimentation procedure in 2 D, by which one can study the model of sequence stratigraphy, predict the distribution of reservoir, modify the interpretation of well logs and seismic data. It can be used to check up the plan of exploration and to predict the basic factors of stratum formation. This article describes a numerical computer model that calculates the internal architecture of carbonate platforms in response to varying values of carbonate production, subaerial and submarine erosion, gravity transport and sediments redeposition. A powerful software system is also developed for modeling sedimentary processes, by which the geometric configuration and tectonic movement can be modeled. The key factors of basin fill are analyzed in detail. The correctness and practices of modeling method are improved by a series of the modeling cases of varying values of factors. One can discern from the simulating illustrations the essential factors of sequence stratigraphy such as transgressive systems tract (TST), highstand systems tract((HST), truncation, etc.
