摘要:
文中通过综合研究岩心观察和成像测井、常规测井、钻井、录井等各种基础资料,结合古构造恢复分析,提出了研究区厚层藻云岩中以古溶洞充填型储层为主导的碳酸盐岩溶储渗体形成机制及分布模式。通过对储渗体内部储层解析,在成像测井和常规测井剖面上识别出了单井钻遇的古溶洞充填型储层和埋藏岩溶储层。根据单井厚度统计,绘制了古溶洞充填型储层分布和相对应的储渗体平面分布图,该结果与气藏实际开发情况一致。
Abstract:
There is a view proposed in this paper that the formation mechanism and distribution pattern of dolomite reservoir-permeability bodies dominated by filled epikarstic paleocave in thick layer algal dolomite in the study area, which are based on the comprehensive analysis of core characterization, FMI, conventional well log analyzing, drilling and logging, combining with the analysis of paleostructure recovery. The reservoirs of filled epikarstic paleocave and of deep buried dissolution encountered in single wells are identified on FMI and conventional well log sections, based on the analysis of the internal reservoir structure of the reservoir-permeability bodies. According to the statistics of filled epikarstic paleocave thickness and reservoir-permeability bodies in single wells, the distribution map of the filled epikarstic paleocaves and the corresponding distribution map of the reservoir-permeability bodies are drawn. The results are consistent with the developing situation of the gas reservoir.
