基于平面相约束的三维砂体构型建模方法
A 3D reservoir modeling method with constraint from planar distribution of sedimentary facies
摘要
Abstract
By introducing the microfacies planar distribution into the 3D sandbody architecture modeling process with 1D well data,a 3D sandbody architecture modeling method constrained by the microfacies planar distribution was proposed.Taking single sandbodies of different microfacies types as the modeling objects,the microfacies planar distribution to constrain the planar distribution range and morphological characteristics of each individual sandbody was introduced,and the 3D sandbody architecture model was established by identifying the top and bottom microstructural surfaces of the sandbody within the pla-nar distribution range.The mathematical model was employed to optimize the microstructural surfaces of individual sandbod-ies,and the superposition relationship was utilized to optimize the contact relationship between sandbodies.The results indi-cate that the method can well characterize different microfacies types of single sandbodies,and exhibit significant advantages in portraying the complex morphological characteristics of sandbodies.It can efficiently depict the complex plane geometric shapes of single sandbodies of varying microfacies types,appropriately reflect the cross-sectional morphological characteristics of individual sandbodies,and reasonably represent the complex contact relationships between different architecture units.关键词
