徐深气田升平区块火山岩气藏合理开发井距的确定

气田合理开发井距一方面使单井能控制足够的储量,低丰度区单井控制储量应大于经济极限储量;另一方面确保单井生产能波及到该井所控制的面积,使气井具有一定的生产供气能力和稳产期,以保证气井生产取得最好的经济效益。通过对升平气藏地质特征的认识,利用国内外类似气藏开发井距经验、经济极限井距、试井分析井距、压裂投产井距等对比分析,确定了升平区块火山岩气藏的合理井距取值。

Determination of Reasonable Development Well Distance of Volcanic Gas Reservoir in Shengping Block Xushen

Reasonable development well distance in gas field could control enough reserves of single well on the one hand,single well control reserves in low abundance area should be more than economic limit reserves,on another hand,to ensure single well production sweeping the control area of the well.So the gas well could have certain gas supply capacity and stable production period,to ensure best economic benefit of gas wells.This paper confirms the value of reasonable well distance of volcanic gas reservoir in She...
