Abstract

The invention discloses a deep reservoir rock core value characterization method comprising the following steps: collecting logging data of a real physics rock core; carrying out a rock core physics experiment so as to obtain simple rock mechanics parameters; using a porosity of the rock core logging data to serve as a reference, and carrying out curve fitting for the physics experiment result data; setting up a value model under a real complex state according to the standard rock mechanics parameters obtained by fitting under certain porosity, thus obtaining mechanics parameters of the rock core whose position is hard to reach in reality, and the physics experiment of the rock core is hard to conduct under the complex real three dimensional state. The method allows an random rock core, having the porosity logging data, to have the standard physics experiment, and the method has specific requirements for the real complex state and corresponding mechanics parameters of the rock core; the value experiment method has very good versatility and practicality.

Description

technical field [0001] The invention relates to a numerical characterization method for mechanical parameters of rock cores in deep reservoirs, in particular to a numerical experimental method based on well logging results and standard physical experiments of rock cores. Background technique [0002] The selection of rock mechanics parameters directly affects the design and research of projects in many fields such as oil and gas extraction, mining, water conservancy and hydropower, and underground engineering. It is an effective method to obtain rock mechanical parameters by drilling cores of certain layers, and then performing rock physical and mechanical experiments. However, due to the complex geological conditions of rock strata, construction facilities and cost issues, the number of actually drilled cores is limited and cannot be obtained. It may cover various horizons required by engineering analysis and research, so only physical experiments on cores cannot fully meet...
