Abstract

Summary

Complex reservoirs often have more variety of pore types and more complex pore shape. For example, carbonate rocks can have a variety of pore types, such as moldic, vuggy, interparticle, intraparticle and crack. This complex pore system makes the relationship between the elastic properties and porosity of the rock highly scattered. This paper have developed a new technique of pore shape substitution that accurately predicts the change in the elastic properties of the rock upon changes in pore shape, assuming no changes in the porosity or fluid. We have applied pore shape substitution to separate the effects of pore shape on the rock stiffness from the effects of porosity. The test results on the real logging data showed that the new method can be used to characterize pore structure.
