摘　　要：以酒泉盆地青西凹陷窟窿山地区下白垩统下沟组为研究对象,开展储层三维地质建模研究。采用确定性与随机性建模相结合的思路,首先利用确定性建模方法建立起扇三角洲平原、前缘和浅湖泥的分布;随后采用随机性的序贯指示建模方法建立岩石相空间分布;最后将确定性模型与随机模型融合,形成高精度的岩石相模型。以岩石相模型为约束,采用相控参数建模方法,建立孔隙度、渗透率的三维分布模型,为后续储层研究与油藏开发、数值模拟奠定了坚实的地质基础。By taking Xiagou Formation in the Lower Crataceous of Kulongshan Area in Qingxi Sag of Jiuquan Basin as the research object,a three-dimensional geological modeling of reservoirs was studied.The idea of deterministic modeling method combined with stochastic modeling method was deployed.First,distribution of fan delta plain,front and shallow lake mudstones was set up by the deterministic modeling method,then the space distribution of the rock facies was built up based on sequential indicator stochastic modeling method,finally,high precision of rock model was created based on the combination of deterministic model and the stochastic model.With the rock model as constraints,the three-dimensional distribution models of porosity and permeability are established by using the Gaussian sequential modeling method,the model provides a solid geological foundation for the subsequent research and numerical simulation of reservoirs.
