摘要
针对罗家寨气藏储层特征,对罗家寨气藏的产能进行分析和预测,分析表明,基于气藏与井筒耦合作用的非稳态产能预测新方法对于单井产能预测的优越性、长远性和实用性,不仅可以直接利用不稳定压力测试成果进行预测,还可以通过生产动态资料拟合来确定地层参数预测,同时也可以用来研究不同工作制度、完井方式以及增产措施改善情况下的产能变化。为衰竭式开采的油藏工程研究提供了先进的手段。
The productivity in Luojiazhai gas reservoir is analyzed and forecasted according to its reservoir characteristic, the result shows that, to single well productivity forecasting, the superiority, duration and practical application of the new approach of transient well test based on coupling gas reservoir and well bore can not only be used to forecast by directly employing transient pressure test data, also, by determining formation parameters through production dynamic data matching, meanwhile, it can be used to study the different work procedure, the way of well completion and productivity change under the condition of improving EOR. The approach provides a advanced means to oil reservoir engineering research of depletion recovery.
