Conference paper
Part of the Springer Series in Geomechanics and Geoengineering book series (SSGG)

Abstract

Sulige Gas Field in the Ordos Basin, a typical tight sandstone gas field with great heterogeneity, has difficulties in its development because its reservoirs are featured by small-scale effective sand bodies, rapid changes, strong plane heterogeneity, and poor connectivity. Analytical well testing widely used in Sulige gas field has more limitations. Numerical well testing, compared with analytical well testing, can more accurately obtain reservoir and wellbore information, can improve the capacity and pressure variation of gas wells in Sulige gas field gas reservoir understanding in the study of different types of gas seepage theory. This text compare the difference between the numerical well testing and analytical well testing, and summarize the main points of numerical well testing analysis technology, and form technical ideas of the numerical well testing technology, and comprehend interpretation process of the analysis of the typical numerical well testing, and obtain the distribution features of the main parameters such as effective permeability reservoir, fracture half-length fracture and diverting capacity and so on by the statistics of vertical Wells, horizontal Wells interpretation results are, and deepen the understanding of reservoir and the modification measures effect evaluation, and provide technical support for the stable gas production.
