摘　　要：为了提高压裂技术在海上低渗气层改造中的增产效果,降低压裂措施施工风险,压裂选井选层研究是一个亟待解决的问题。以海上某气田低渗储层动静态资料为基础,运用数值模拟方法,对压裂后的产能进行了预测,得到了海上某低渗气田压裂厚度及含水饱和度界限图版,利用该技术界限图版,可以根据储层的渗透率,判断出海上低渗气藏压裂选井选层的厚度及含水饱和度界限,极大地提高了工作效率和压裂层增产效果。In order to improve the effect of fracturing stimulation in low permeability layer of offshore gas reservoir,reduce the risk of fracturing,wells and layers selection is a problem to be solved.Based on the reservoir geological conditions and the analysis on static and dynamic geologic data,numerical simulation models of different conditions has been established for predicting the fracturing production.The technology limit chart can be used to judge the thickness and water saturation limit for the selection of the wells and layers. The study has greatly improved the efficiency and stimulation effect.
