摘要:

与碎屑岩储层相比,碳酸盐岩储层具有极强的非均质性,储集空间类型多,孔、洞、缝发育不均,如何表征强非均质性碳酸盐岩气藏的三维储集空间是储层精细描述的关键。基于地质、测井、地震及生产动态等数据与资料,在气藏精细描述与储层评价认识的基础上,以合川区块茅口组缝洞型碳酸盐岩储层为研究对象,采用随机建模结合确定性建模方法,逐步构建构造框架、沉积相分布、储层分类及孔隙度、渗透率及含气饱和度等多种属性的储层精细地质模型,定量表征储层属性分布特征;采用地质统计学结合多属性协同模拟技术,建立多尺度融合的缝洞体模型,定量刻画储层储集空间展布特征,形成了一套基于沉积相-储层类型分级控制与多尺度信息融合的缝洞型碳酸盐岩精细储层建模方法。

Abstract:

Compared with clastic reservoirs,carbonate reservoirs have extremely strong heterogeneity,multiple types of storage spaces,and uneven development of pores,caves,and fractures.How to characterize the three-dimensional storage space of strongly heterogeneous carbonate gas reservoirs is the key to fine reservoir description.By integrating geological,logging,seismic,and production dynamic data with reservoir characterization insights,this study focuses on the Maokou Formation fracture-dong carbonate reservoir in Hechuan Block.Random modeling combined with deterministic modeling methods is used to gradually construct a detailed geological model of the reservoir with various attributes such as structure,sedimentary facies,reservoir classification,porosity,permeability,and gas saturation,quantitatively characterizing the distribution characteristics of reservoir attributes.By combining geostatistics with multi-attribute collaborative simulation technology,this paper establishes a multi-scale integrated fracture-hole model,quantitatively characterizes the spatial distribution characteristics of reservoirs,and forms a set of fine fracture-hole carbonate reservoir modeling methods based on sedimentary facies-reservoir type classification control and multi-scale information fusion.
