The invention discloses a horizontal transverse wave sensitivity continuous depth processing method and a device. The processing method discloses by the invention comprises steps of obtaining logging data, calculating a first rigid coefficient and a second rigid coefficient according to the logging data, calculating a third rigid coefficient and a fourth rigid coefficient according to the first rigid coefficient and the second rigid coefficient, substituting the first rigid coefficient, the second rigid coefficient, the third rigid coefficient and the fourth rigid coefficient into a stoneley wave dispersion equation to calculate instrument equivalent modulus, generating horizontal transverse wave speed according to the fact that the instrument equivalent modulus performs inversion on the stoneley wave, and calculating horizontal transverse sensitivity according to the horizontal transverse speed. Through the invention, the credibility of the stoneley wave performing inversion on the horizontal transverse wave can be investigated so as to accurately represent the elasticity property of the unconventional oil gas stratum and lay a good foundation for evaluating the minimum horizontal main strain and bursting pressure.
Description
technical field [0001] The invention relates to the application technology of acoustic wave logging processing in petroleum exploration and development, in particular to a method and device for continuous deep processing of horizontal shear wave sensitivity. Background technique [0002] With the continuous development of oil and gas exploration and development, unconventional oil and gas such as tight gas, shale gas, coalbed methane, and tight oil have shown great potential under economic and technical conditions, and global oil and gas resources will usher in a second expansion. Experiments show that unconventional oil and gas reservoirs are usually laterally isotropic formations. To evaluate the elastic properties of laterally isotropic formations, five rigidity coefficients are needed, namely C 11 ,C 13 ,C 33 ,C 44 ,C 66 , according to the Annie model, C 13 =f(C 33 ,C 44 )=C 12 =f(C 11 ,C 66 ), where C 33 and C 44 can be obtained from conventional acoustic l...
