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 quantitatively and intuitively display the three-dimensional physical property parameters and geometry of the reservoir, and improve the accuracy of inter-well physical properties interpolation so as to improve the precision of reservoir fine description. The Z30 block in the eastern zone of Sulige gas field develops in the river facies and the sand body changes rapidly laterally and the reservoir prediction is more difficult. Therefore, using the Petrel software and drilling data as a reference, the reservoir is established according to the point-surface-body modeling procedure Z30 block structure model. On this basis, the sedimentary microfacies model was constructed by using sequential indicator simulation method based on single well facies data of logging interpretation. Using phase-controlled modeling technique as the guide, a series of sequential Gaussian simulations Methods The reservoir property model was established. Reservoir modeling provides a reliable basis for accurate assessment of reservoir properties and potential, and also provides a geological basis for the adjustment of gas reservoir development programs.
