以半经验算法为基础的二维空间地层模拟程序已成功地应用于碎屑岩、碳酸盐岩与混合碎屑岩/碳酸盐岩沉积。这种方法可用来预测储层分布,调整井和地震资料的解释。在边缘盆地里检验勘探方案,以及对盆地地层的基本控制因素进行评价。从Main Pass(美国墨西哥湾岸区)、沙捞越海岸(马来西亚)以及巴尔的摩峡谷(美国东海岸)的地震、钻井及测井等资料的应用中,证明了这种方法不仅可以对整个盆地,而且还可以对盆地的某一局部地层进行模拟。 Main Pass盆地的横剖面为一套晚第三纪海退超覆碎屑岩。模型以200ka为单位模拟17Ma的地质历史。再现了整个盆地的几何形态,主要层序的边界、深度、以及近岸海相砂岩的位置,注入的深水区沉积物区间,陆架边缘的位置及古水深。利用优化重建的碳酸盐岩长势的海平面史,模拟了Luconta中部,沙捞越(马来西亚)近岸的三个晚第三纪碳酸盐岩建造。模拟结果再现了实际地层的反射几何空间、海进、加积、推进、海岸线后退及出露的海岸平原。程序同时也模拟了侏罗系更新统的盆地以及沿巴尔的摩峡谷地槽300km倾斜线地层层序的几何形态,以及混合碎屑岩/碳酸盐岩相的分布。有趣的是本模拟包括了一个推进的中侏罗纪海平面低水位期碎屑岩剌穿的碳酸盐岩边缘,以及一个在晚侏罗纪到白垩纪发育达到极点碳酸盐岩加积而后期沉没于水下的弧立碳酸盐岩隆起。对于早白垩纪加积的边界来说,模拟的古水深和相之间的关系与描述的岩相古地理及地震地层的解释相一致。
Two-dimensional space formation simulations based on semi-empirical algorithms have been successfully applied to the detrital, carbonate and mixed clastic / carbonate depositions. This method can be used to predict reservoir distribution, adjust well and interpretation of seismic data. Inspecting exploration programs in marginal basins and evaluating basic controls on the formation in the basin. The application of such data from the Earth Pass, the Sarawak shores (Malaysia) and the Baltimore Gorge (east coast of the United States) to drilling and well logging data from the Main Pass (U.S. Gulf Coast) proved that this method can be applied not only to the entire basin but also It is also possible to simulate a partial formation in the basin. The cross section of the Main Pass Basin is a Late Triassic overthrust clastic rock. The model simulates 17Ma geologic history in units of 200ka. Reproduced the entire basin geometry, the boundary and depth of the main sequence, as well as the location of the coastal marine sandstone, the sedimentary interval of the injected deep water, the location of the edge of the shelf and the paleo-water depth. Using the sea-level history of carbonate soils optimized for reconstructions, three Late Tertiary carbonate rocks were simulated in the central Luconta and offshore of Sarawak (Malaysia). The simulation results reproduce the reflected geometric space of the actual formation, sea coasting, accretion, propulsion, shoreline receding and exposed coast plains. The program also simulates the geomorphology of the stratigraphic sequence of the Jurassic Pleistocene basins along the 300 km slope along the Baltimore Gully Terrain and the distribution of mixed clastic / carbonate facies. It is interesting to note that this simulation includes a carbonate rift pierced by clastic lower-water stage clastic rocks in the mid-Jurassic stage and a pole-fill carbonate reservoir developed during the Late Jurassic to Cretaceous and later The arc-shaped carbonate rock submerged under water rises. For the Early Cretaceous accretion boundary, the relationship between simulated paleo-water depths and facies is consistent with the interpretation of lithofacies paleogeography and seismic stratigraphy.
