鄂尔多斯盆地下古生界气藏地质建模技术

Geological model on the Lower Paleozoic carbonate reservoir in Ortos basin

摘要: 针对鄂尔多斯盆地中部气田下古碳酸盐岩储层非均质性强的主要矛盾,以随机模拟建模为主要方法,对该区地质研究和气藏描述成果进行定量化转变,形成了包括构造模型、物性模型和流体分布模型的鄂尔多斯盆地下古碳酸盐岩整体地质模型。以此模型为基础,进行储量的风险估计、归纳气井产能与地质情况的关系、提供井位优选的参考依据及提供气藏数值模拟的网格参数场。

Abstract: In view of the main feature of strong anisotropism of reservoir Stratum of the Paleozoic Era carbonate rock in the middle part of Ortos basin gas field, mainly by means of random analog formation, this paper makes a quantitative tranformation on the geological study on the area and the descriptive results of the gas pool, and finishes the whole geological model of underground carbonate rock in Ortos basin, including the structure model/physical model and fluid distribution model. Based on the model,the paper also makes a risk evaluation of the reserves,genevaizes the relationship between the gas well capacity and the geological condition,and provides reference data about the best location of well and network parameter about gas pool numerical simulation.
