Problems solved by technology

[0003] Due to the large burial depth of deep-ultra-deep oil and gas reservoirs, coring is difficult, the time period is long, and the cost is extremely high; there are many factors affecting coring, and the result is highly uncontrollable, especially the distribution of coring sections is limited, accounting for only 100% of the entire well. 0.1%, accounting for 10% of the target layer, the representativeness of the core analysis results is quite different from the real situation of the formation

Abstract

The invention discloses a digital modeling method and device for a continuous shaft of a deep reservoir. The method comprises the following steps of calculating the volume content of stratum mineral components according to a gamma-ray spectrum acquired by ECS, calculating the rock porosity according to the volume content of the stratum mineral components, carrying out full-diameter digital core modeling, matching the rock porosity and the ore group component proportion obtained by calculating the corresponding depth of the rock core with the full-diameter digital rock core, and performing deep reservoir continuous shaft digital modeling according to the rock porosity data of each layer section and the matched full-diameter digital core. In the way, well logging interpretation results are matched with multi-scale digital cores, and well logging and CT cross-scale joint description of deep reservoir continuous shaft digital modeling is achieved.

Description

Technical field: [0001] The invention relates to the technical field of oil and gas exploration and development, in particular to a method and device for digital modeling of continuous well bores in deep reservoirs. Background technique: [0002] In recent years, as wells such as Bozi 9 in the Kelasu structural belt of the Tarim Basin have successively achieved high yields, deep-ultra-deep oil and gas have become more realistic exploration breakthrough targets and resource replacement areas. The degree of exploration of deep-ultra-deep oil and gas is relatively low, and the heterogeneity and concealment are stronger. A large number of cores are drilled, and core analysis experiments such as geochemistry, lithology, physical properties, and oil-bearing properties are carried out to analyze reservoir characteristics and influences. factor. [0003] Due to the large burial depth of deep-ultra-deep oil and gas reservoirs, coring is difficult, the time period is long, and the co...
