Transient pressure behavior analysis in a banded reservoir with partially communicating faults
摘要
Abstract
Banded reservoir is one of the most common structures in fault block reservoir, most of the researches on non-closed faults are concentrated in homogeneous reservoirs and composite reservoirs.When we used the existing well testing interpretation models to inter-pret the actual banded reservoir well test data with partially communicating fault boundary, the obtained results are not always ideal.A well testing model for wells located near a par-tially communicating fault in a two-zone,banded reservoir was established by introduced the"boundary skin"concept,the solution was obtained with the Fourier and Laplace transforma-tion.Type curves were plotted by the Stehfest numerical inversion method and this model was verified by the examples.The result showed that the bigger the boundary skin value,the more the curve upturned;the boundary distance has a significant effect on the typical curve shape;the mobility ratio,thickness ratio,pressure conductivity coefficient mainly affected the pressure derivative curve rise and fall..关键词
