Abstract

Abstract: There are differences between dynamic and static elastic parameters of shale.Thus when applied,they need to be converted.Most experiments carried out today by both domestic and foreign scholars in testing rock dynamic and static elastic modulus conversion are under normal temperature and pressure,without considering the influence of temperature and pressure on the results;consequently,the conversion results cannot fully display the mechanical properties of reservoirs.We studied the Wufeng-Longmaxi black shales of the Upper Ordovician and Lower Silurian in the Sichuan Basin,conducted mechanical experiments of rock dynamic and static elasticity under different temperatures and pressures,and analyzed the test results.The results show that:① when the temperature and pressure are constant,the dynamic Young's modulus test value is larger than that of the static Young's modulus test,and the two have a certain linear correlation.② The dynamic and static Young's moduli for shales are correlated with temperature and pressure.When the temperature keeps constant,the static and dynamic Young's moduli of shales increase with the increase of confining pressure.When the pressure is constant,the static and dynamic Young's moduli of shales decrease with the increasing temperature.Besides,the mechanism for the change of dynamic and static elastic mechanical parameters under different temperatures and pressures was analyzed.③ The conversion model for dynamic and static elastic parameters of shales under different temperatures and pressures was established.In applying the model,whatever the temperature and pressure,the dynamic elastic parameter obtained can be converted into the in-situ static one,and the results are reliable.This model can provide credible static moduli of elasticity for shale gas exploitation and hydraulic fracturing in the study area.All in all,the research is of certain practical significance.
