摘要

水平井分段完井应用前景广阔，但国内外相关研究均是以油藏为基础。根据气体稳定渗流理论及水平井三维渗流特征，通过引入流量相关表皮系数推导出了气体非达西渗流影响下微元水平段的拟压力分布，进而基于拟压力降叠加原理建立了水平井分段完井气藏模型；再结合分段完井井筒模型建立了其产能预测耦合模型。实例验证表明耦合模型准确度高；继而对气藏水平井分段完井产能进行了预测，并给出了相应流率、轴向流量及井筒流压沿井筒方向的分布。

Abstract

The application of partially completed horizontal well is very promising,but the relevant researches worldwide are only based on oil reservoir. According to the stable percolation theory of gas and three dimensional seepage characteristics of horizontal well,the pseudopressure distribution of infinitesimal horizontal section influenced by non-Darcy flow was derived by introducing skin factor related to flow rate. Furthermore,based on the superposition principle of pseudopressure drop,the gas reservoir model for partially completed horizontal well was established. And the coupling model for production prediction was founded by coupling gas reservoir model and wellbore model. The verification for this model against reality case indicates a high accuracy. Utilizing this coupling model,the predicted production and the distribution of flow rate,axial production and flowing pressure in wellbore along horizontal well of partially completed horizontal well are obtained.
