油气藏压裂酸化效果评价技术研究进展

Studied Advance about Technique of Evaluation to Effect of Fracturing Acidizing in Reservoir

压裂酸化作业成本较高、风险性大,对于探井,施工效果的好坏还直接影响到油气田勘探开发决策的制定。从室内试验、施工曲线分析、增产倍比计算、生产测井评价、压力不稳定试井、压后压力诊断分析以及压后动态评估等七方面对各种油气藏压裂酸化效果评价技术进行了分析,并对国内外各种评价技术的研究进展进行了综述。

Operation of fracturing and acidizing is high cost,high risk,whose effect directly influences on making decision of exploration and development.Tech of evaluation for effect on fracturing and acidizing in all kinds of reservoir is analyzed from 7 aspects,such as indoor testing,construction curve analyzing,times or ratio of increase productivity calculating,production logging evaluating,transient testing,pressure diagnosis analyzing and performance assessing after analysis so on and comprehensive summarizing of every kind of evaluation tech at home and abroad is conducted.
