| Abstract: | In the paper,the palaeotectonic st ress field and its boundary condition of Himalayan movement,which played an impo rtant role in the deformation of West Sichuan Depression and the formation of tr aps,are inversed according to structural deformations;the other geological model s are described by use of palaeostructural maps and rock mechanical param eters;and the numerical simulation of tectonic stress field is carried out for t he major reservoirs as Xujiahe Formation,Shaximiao Formation and Penglaizhen For mation,then,by applying its results,the structural fracture distribution is pred icted according to Coulomb Mohr Criterion,thus providing reliable geological ba sis for oil and gas resource assessment and exploration deployment. |
