Embodiment Construction

[0070] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0071] The development of low-permeability reservoirs mainly increases single-well productivity through hydraulic fracturing, and maintains formation energy by water injection. The seepage mechanism and dynamic changes in the reservoir after oil-water well fracturing largely depend on the parameters and orientation of hydraulic fractures. Oil well production (initial production, stable time and cumulative production, etc.) is not only related to hydraulic fracture parameters, but also related to factors such as water injection intensity and well pattern. The development of low-permeability oilfields is different from conventional oilfields in the duality of hydraulic fracturing. On the one hand, the exist...

Abstract

The invention provides a full-sew-length three-dimensional crushing data simulation method and device for oil and gas reservoir development. The method comprises obtaining pre-stack seismic data of an oil and gas reservoir development object region, obtaining the pre-stack seismic data to conduct elastic parameter inversion and obtaining an elastic parameter data body of the oil and gas reservoir development object region, constructing a rock mechanic parametric model based on three-dimensional grid nodes according to the elastic parameter data body, calculating stress information on the three-dimensional grid nodes, generating three-dimensional stress field distribution model; and conducting full-sew-length three-dimensional numerical simulation in a crushing process according to the rock mechanic parametric model and the three-dimensional stress field distribution model. The full-sew-length three-dimensional crushing data simulation method and device can improve accuracy and efficiency of crushing data.

Description

technical field [0001] This application relates to the technical field of oil and gas reservoir development, in particular to a method for full-fracture-length three-dimensional fracturing numerical simulation for oil-gas reservoir development, and a full-fracture-length three-dimensional fracturing numerical simulation for oil-gas reservoir development installation. Background technique [0002] my country has 6.6 billion tons of low-permeability oil and gas reserves that have not been developed. In recent years, the scale of low-permeability oil and gas production capacity construction accounts for more than 70% of the country's total, and has become the main battlefield for increasing oil and gas reserves and production in my country. The core issue to achieve economical and effective development of low-permeability hard-to-produce reserves is to find out the reasonable matching between the spatial distribution of artificial fractures and well pattern after fracturing, an...
