Research On Reasonably Production Proration Plan In Xu Deep Volcanic Gas Reservoir

Xu deep volcanic gas reservoir is typical of lithology complexity, severity inhomogeneity, big difficulty of extract. Nowadays, it hasn't come into being some method and experience which for volcanic gas reservoir. It exist edge water or basal water in Xu which is based on data of producing test well, so we must carry out synthetical research from multi-effect factor to confirm reasonably production and extract method which can make gas well output reaonably and prevent from flooding , we can get a big degree of reserve recovery.The paper which is based on natural gas supervise design is that we can get deliverability equatio and AOF which depends on reservoir depict and develop feature by means of static and dynamic state data and early research;establish multiphase conduit flow model which is based on nodal system analysis method to calculate harmonize production;calculate well reserves applying drawdown method;confirm interface throughput capacity considering temperature and pressure;optimise calculate method which is used for water coning interface production depending on well means of production;study fluid distribute rule which can get well water out situation. it is a reasonably production proration method depending on these study which including multi-element in Xu gas reservoir that capacity use,pressure drawdown,gas recovery rate,water out and throughout water data is reasonably,so we can long term use it to guide gas field exploitation.
