摘　　要：地质建模可以定量、直观地展示储层三维物性参数及几何形态,提高井间物性的内插精度,从而提高储层精细描述的精确度。苏里格气田东区Z30区块储层发育于河流相,砂体横向变化快,储层预测难度较大,故利用Petrel软件,以钻井数据为基准,按照点—面—体的建模步骤建立Z30区块构造模型;在此基础上,以测井解释单井相数据为基准,采用序贯指示模拟方法构建了沉积微相模型;并以相控建模技术为指导,采用序贯高斯模拟方法建立了储层属性模型。储层建模研究为准确评价储层性质及潜能提供了可靠依据,也为气藏开发方案的调整提供了地质依据。Geological modeling can improve the interpolate precision of properties between wells and the reliability and accuracy of reservoir description through establishing a 3D geological model which can show the style of reservoirs directly and 3D quantitative reservoir distribution parameter and geometry.Since the reservoirs of Z30 block in the eastern part of Sulige gas field were developed in the fluvial sedimentary environments and the sandbodies vary laterally fast,it increases the difficulty to forecast reservoirs between wells.According to the basic modeling steps from point to surface to body,the tectonic model of the research block was constructed according to the drilling data by using the Petrel software.Then,based on facies data interpreting from logging of single well,the detailed sedimentary facies model could be established by using the sequential indicator simulation method.Finally,based on the facies model,the properties parameter model was built by using facies controlling modeling technology and sequential Gauss simulation method.Through the simulation study of Z30 block,it can increase the precision of reservoir description,and it also can provide geologic reference for working out and regulating reservoir development program.
