摘要/Abstract

摘要： 针对非均质性强烈的复杂储层水平井开发，将水平段测井资料进行采样离散化，并以虚拟直井的方式提取测井曲线，进而从深度域开展岩性随机模拟反演。该方法不仅可以将水平段测井资料有效应用，而且可以根据水平段随钻测井的逐步更新实现水平段动态定量预测。通过大牛地气田试验分析认为，该技术可明显提高单砂体顶底构造及储层内部隔夹层预测精度，对于提高水平井储层钻遇率具有显著效果。

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
