Abstract

Abstract

As the rock mechanics parameters such as Young modulus and Poisson ration are the basic data for drilling and completion as well as design for reservoir fracturing in oil field, and for simulation of tectonic stress field in sedimentary basin, it is the key contents that obtain rock mechanic parameters during petroleum exploration and development. Based on rock mechanic test and relations study between compressional wave slowness and shear wave slowness, this paper established the undetermined coefficients of the formula for shear wave slowness based on conventional logging data. The values obtained through the least square method for the three undetermined coefficients A, B and C are 2.74, 25.45, -370.16 respectively. The calculated shear wave slowness is consistent to the tested ones. Based on the calculated method, the results of Young modulus and Poisson ration of the Upper Paleozoic of Ordos Basin are range from 35593 MPa to 37997 MPa and from 0.21 to 0.25 respectively. The establishment of the formula for the rock mechanics and the study on the rock mechanical parameters laid a theoretical foundation on the research work of gas field exploration and development.
