Summary: | 碩士 === 國立成功大學 === 資源工程學系碩博士班 === 92 === The purpose of this study is to use numerical solution to build up type curves and to analyze and monitor the effect, influence and range of leakage or production/injection wells in a gas/oil (storage) reservoir.
Using the program, IMEX, of Computer Modeling Group Ltd. To construct exhaust reservoir model and waterdrive reservoir model, if production/injection can be considered as a leakage point, the effect of the leakage on the transient pressure of the testing well is easy to be observed. The methods are to plot type curves with the simulation pressure data, to recalculate the distance between these influence wells and the testing well.
In this study, we construct type curves for exhaust and waterdrive reservoir with no extra production wells. There is a “V” pattern effected by the reservoir boundary in the dimensionless pressure derivative curves. The reason that causes the “V” pattern may be the strong waterdrive. Also, we build up type curves for exhaust and waterdrive reservoir with one and two production/injection wells. And to use different method to recalculate the distance between the testing and production/injection wells. The calculating results are very close. We provide the suggestions which methods are suitable for our model.
