Abstract

Abstract: Aiming at horizontal well development of complex reservoir with strong heterogeneity, logging data of the lateral can be discretized in the form of virtual vertical wells, and further to carry out lithology stochastic simulation inversion in depth domain.It not only can effectively use the horizontal well logging data, but also can realize quantitative prediction of the laterals through the updating of logging while drilling in the laterals.Its application in Daniudi gasfield shows that significant improvement of prediction accuracy is achieved in respect of top and bottom structural framework of the single sand body and the barriers and baffles within the reservoir, and the reservoir penetrating ratio of horizontal wells is significantly increased.

Key words: inversion in depth domain, virtual vertical wells, horizontal section, horizontal well, Daniudi gasfield
