Abstract

The invention provides a conglomerate reservoir evaluation method based on gravel component analysis. On the basis of conglomerate gravel component analysis, microscopic characteristics (gravel components and surface porosity) and macroscopic characteristics (reservoir pore permeability and oil and gas productivity) of a conglomerate reservoir are combined, and the control effect of the conglomerate gravel components on an oil and gas reservoir is discussed, so that a correlation between the gravel components and reservoir physical properties and oil and gas productivity is established. The conglomerate reservoir evaluation method based on the gravel component analysis is a direct reservoir geological evaluation method and can accurately and conveniently evaluate the conglomerate reservoir without depending on geophysical logging information, so that the exploration and development of the conglomerate oil and gas reservoir are accurately and quickly guided.

Description

Technical field [0001] The present invention belongs to the technical field of gravel reservoir evaluation method, and specifically, a gravel reservoir assessment method based on gravel component analysis. Background technique [0002] As my country's main oil gas basin is getting higher and higher, there has been entered a new stage of rocky stratum oil and gas reservoirs and structural oil and gas reservoirs, and the rock formation of rock formation is quite a period in the future. The most realistic, most potential, and most universal oil and gas exploration areas. [0003] As a rocky oil and gas hood, the gravel rock oil is gradually attracted by people worldwide, and the gravel reservoir has a low porosity, low permeability and strong homogeneous characteristics. The agresses are mainly controlled by deposition phase, rock, fluid, structural activity, particulate component, fill type, and filling method, particle size distribution, particle contact mode and other factors. Th...
