摘要:

火山岩气藏储层岩性岩相变化快,气水关系复杂,若配产不合理,会造成能量损失、储层伤害、井底积液甚至
水淹等问题,严重影响气井产能和气藏采收率。徐深气田单井控制储量小,产能低,开采过程中压力下降快,产量递减
快,产水现象普遍。传统的单因素配产方法已不能满足生产需要。根据系统试井产能分析、节点系统分析、出水动态
分析、单井动态储量分析以及携液临界流量和底水锥进临界产量的计算,以能量合理利用、压降均衡、采气速度均衡、
有效控水、携液安全为原则,综合考虑地层压力、井底流压、生产水气比等对配产界限的动态影响,对气井配产进行优
化,形成了一套适合火山岩气藏气井开采的多因素动态配产方法。

Abstract:

The volcanic gas reservoirs are the characteristics of rapid variation of lithology and lithofacies and complex gaswater
relation,which can result in severe problems including energy loss,reservoir damage,bottom-hole liquid accumulation,
and water flooding,ultimately have serious influence on gas well productivity and gas reservoir recovery under the condition of
irrational allocation. There are the some problems of small single well control reserves in Xushen gas field,low productivity,
rapid pressure decreasing during development,rapid production decline and general water production. The traditional single
factor allocation methods can not meet the needs of production. According to the productivity analysis of systematic well testing,
node system analysis,dynamic analysis of water production,dynamic reserves analysis of single well and the calculations
of critical liquid carrying flow rate and critical production bottom water coning,and with comprehensive consideraction of
dynamic influence on allocation bound from various allocation bounds,stratum pressure,bottom hole pressure and production
water/gas ratio,this paper has optimized the gas well allocation and finally formed a set of multi-factor dynamic allocation
methods for volcanic gas reservoirs under the principles of rational energy utilizing,pressure drop equilibrium,gas production
rate balance,effective water control,safe liquid carrying and effective control of bottom water coning. This method has been
practically applied in XS gas field and acquires good effect.
