Application of Stress Variation Analysis to Prediction of Buried-Hill Fracture of Ordovician in Lunnan Area

Abstract

Abstract: 3D MOVE and 3D STRESS models are used to analyze the fault, fracture shape and distribution of buried hill of carbonate rocks in Lunnan area, including the stress mechanism, stability and slip vector of fault faces, the extension tendency, slip tendency and factors of seepage and leakage of fracture and fault faces. The reservoirs controlled by the fault and fractures are predicted, and the connection and stability of fractures are analyzed, in order to effectively guide exploration and development in the studied area.

Key words: Lunnan, Ordovician buried hill, sub-seismic fracture, fracture prediction, stress analysis, extension tendency, slip tendency
