Study on Plastic Strain and Plastic Strain Rate in Machining of Steel AISI 1020 using FEM Analysis

摘要

Based on analyzing and testing the core samples of three inspection wells, we research in-layer heterogeneity of the main types monosandbody; in order to build macroscopic analysis on the difference of physical properties in reservoir interbedded, we can also draw distribution diagram of the interbedded sandstone's average porosity and permeability through the physical property data in the study area, meanwhile it is necessary to use statistic data of physical parameters including variation coefficient, mutation coefficient and range to draw tables, which can show the degree of heterogeneity of monosandbody in the reservoir become much stronger from top to bottom; In addition, according to the study of plane microfacies and monosandbody, the information relating to the heterogeneity of the main monosandbody can be acquired. In conclusion, it is clear to know the distribution characteristics of remaining oil deriving from FuYu oil layer in the Chao 45 Block, and the distribution area of residual potential of microfacies by reducing the heterogeneity of reservoir to improve the connectivity, and then increase the mining effect.
