Abstract:

A multi-parameters inversion method in prestack domain is proposed. A lithology model near well is established, of which the parameters include layers time, P-wave velocity, S-wave velocity and density. Under the guidance of Gassmann fluid substitution theory, the permeable layers could be distinguished from impermeable layers. According to the characteristics of the study area, the rock-physics regression relation and prior model of each layer are established. In the basis of Bayes principle, the linearized Zoeppritz equation and convolution model are applied to obtain the posterior probability density of the lithologymodel. The results of the testing byMarmousi2 model show that we could obtain not only accurate inversion result, but also the sensitivity information indicating the existence of oil and gas of each parameter, which could reduce the risk of final exploration.

Key words: ultra-lowpermeability reservoir, geologic features, technical development strategies, pilot tracey
