Abstract

Abstract:

It is necessary to refine the model grid for the process of the numerical simulation of the volcanic gas reservoir because
of the complex reservoir lithologies，lithofacies and developed fractures. The history fitting of the numerical simulation，which
has ambiguity，different grid refinement，and different property parameter combinations，may accomplish the similar results.
The research was carried out to minimize the uncertainty while refining the model. How to reduce the uncertainty to the lowest
degree is a challenge in the numerical simulation of volcanic gas reservoir at Xushen Gas Field. The research results have
identified three well-testing models according to the characteristics of storage-seepage structures of Xushen Gas Field and
proposes a new method which revises the numerical model with well-testing models. The result indicates that it can improve
the accuracy of the numerical model and forecasting results. It is important to develop the remained reserves，set the appropriate
production rate and optimize the development plans.

Key words: volcanic gas reservoir, storage-seepage structure, well test interpretation, numerical simulation, local grid refinement,
