川东石炭系气藏完井增产措施地质效果分析

Geological analysis of completion stimulation in carboniferous reservoir of east Sichuan

文中从压裂酸化工艺技术角度出发 ,对川东石炭系气藏储层特征进行了描述。分析石炭系储层完井增产作业所要解决的主要问题 ,在统计分析川东石炭系气藏上百井次酸化资料的基础上 ,开展不同气井类型、工艺措施、施工规模以及完井方式与压裂酸化效果的研究 ,提出以投入和产出的经济效果来优选各类气井完井增产措施的最佳方案。

On the basis of fracturing and acidizing technology,reservoir characteristics of carboniferous reservoir in east Sichuan are expounded.Some problems are analysed in completion stimulation operation in carboniferous reservoir.On the basis of statistical analysis of acidizing data in carboniferous reservoir of east Sichuan,studies have been done on different gas well type,processing measures,operating scale,completion method and fracturing and acidizing result.Optimum scheme of completion stimulation of all kinds of gas well is proposed according to economic benefit according of input-output.
