摘要
页岩气是一种重要的非常规资源,我国页岩气资源量巨大。国内非常规天然气的勘探开发还处于探索阶段,目前迫切需要开展页岩气井的动态分析研究。通过对传统的Arps产量递减分析方法以及1/q^t0.5分析方法的介绍,探讨了两类方法在页岩气井递减分析预测中的适用性,并将预测结果与数值模拟结果进行对比。最后应用1/q^t0.5分析方法对已投产的两口页岩气井水平井,X井和Y井进行了短期的产量预测。
As an important unconventional energy source in China,shale gas is rich in resources. However,the exploration and development of unconventional gas are still in an exploratory stage. So,the study on dynamic analysis of shale- gas wells should be carried out very urgently. In this paper,traditional Arps method of production decline analysis and 1 / q ~ t0. 5method are presented; the applicability of these two methods are discussed in terms of predicting production decline of shale- gas wells,and the prediction result is compared with that of numerical simulation; at last,1 / q ~ t0. 5method is applied to two horizontal wells( X and Y,which have been put into operation) for short- term production prediction.
