摘要:
以随机函数理论为基础,采用相控-多参数协同的随机建模方法,建立塔河油气田AT1区块凝析气藏三维地质模型,实现气藏精细三维表征。首先,以钻井和岩芯资料为基础构建储层构造模型;然后,以小层界面为控制条件建立储层结构模型;接着,在沉积相、地质条件的约束下,采用序贯指示模拟法来建立砂体骨架模型;随后,在砂体骨架模型内进行优势相计算,形成最终有效砂体骨架模型;最后,以有效砂体骨架模型为约束,采用序贯高斯模拟法建立储层物性参数模型。结果表明:将物性参数变量与微相分布结合的序贯高斯模拟法建立孔隙度等物性参数的分布模型,以及采用地质分析类比、地质统计分析等方法优选最佳模型是有效的地质建模方法;所建地质模型精确细致地表征了塔河油气田AT1区块凝析气藏构造格架及储层、流体三维分布,反映了辫状水道复合连片,东北向展布,储层物性受相控较明显,非均质性较强。
Abstract:
Based on the random function theory, three-dimensional geological model of the condensate gas reservoir in AT1 Block of Tahe Oilfield was built by the phase control and multi-parameter cooperative stochastic modeling method, and three-dimensional quantitative characterization of the gas reservoir was realized. Firstly, structure model of reservoir was built based on the data of drilling and core; secondly, structural model of reservoir was built under the control condition of substratum interface; thirdly, skeleton pattern of sandbody was built by sequential indicator simulation method under the sedimentary facies and geological condition; fourthly, phase preference was calculated with the skeleton pattern of sandbody, and then the final pattern was built; finally, physical parametric model of reservoir was built by sequential Gaussian simulation method under the control of effective skeleton pattern of sandbody. There are effective geological modeling methods that combined physical parameters with micro facies distribution, sequential Gaussian simulation method built the distribution model of physical parameters porosity, and optimization model was selected by geological analysis, analogy and statistics. The geological model built showed the tectonic framework, reservoir, fluid three-dimensional distribution of condensate gas reservoir in Block AT1 of Tahe Oilfield accurately and meticulously, and indicated that braided stream was complex and connected, physicality of reservoir was controlled significantly by facies, the direction of distribution was northeast, and the inhomogeneity was strong.
