A pressure gradient model for fluid inflow from tube wall in perforation section is presented. The effect of effective wall friction factors on pressure gradient is discussed. The coupling model for wellbore and reservoir is developed. The supposation that the productivity index is constant along a horizontal well is extended.

建立了水平井筒油藏流体从管壁流入时孔眼段流体压力梯度模型 ,讨论了井筒有效管壁摩擦系数对流体压力梯度的影响。在此基础上 ,建立了同时考虑井筒流体流动和油藏渗流的井筒油藏耦合模型 ,该模型将Dikken模型中沿整个水平段单位长度生产指数为常数的假定进行了推广。在给定条件下对压力降模型进行了讨论 ,计算了单个孔眼段的压力损失。计算结果表明 ,水平井段较长或产量较高时 ,水平段流体压力降比较明显。

Snaky well is a new type of complex well. Its producing well section is rugged longitudinally. The flow property of Snaky wellbore is different from horizontal pipe and horizontal well's. The article researched the flow property of Snaky wellbore and analyzed the flow for the mini-element section and perforation section of the snaky well. Based on the continuity equation and the momentum equation, the pressure fall models of wellbore flow within an open-hole and a perforated completion snaky well bore are established...

Snaky well is a new type of complex well. Its producing well section is rugged longitudinally. The flow property of Snaky wellbore is different from horizontal pipe and horizontal well's. The article researched the flow property of Snaky wellbore and analyzed the flow for the mini-element section and perforation section of the snaky well. Based on the continuity equation and the momentum equation, the pressure fall models of wellbore flow within an open-hole and a perforated completion snaky well bore are established .The calculating methods of pressure fall were proposed for producing well section of the snaky well under the two working systems of constant production and constant bottom-hole pressure. The pressure fall of the producing well section of an open-hole completion snaky wellbore was calculated separately using the model established in the article and the calculating model of pressure fall for the horizontal section of the horizontal well .The results showed the pressure fall of the producing well section of snaky well couldn't be calculated with the pressure fall model of the horizontal sections of conventional horizontal wells. The pressure fall of producing well section of snaky well couldn't be omitted.

蛇曲井是一种新型复杂结构井,生产井段存在较大的纵向起伏,井筒流动特征既不同于普通水平管,也不同于水平井。研究了蛇曲井井筒流动特征,对蛇曲井微元段和孔眼段的流动进行了分析,根据质量守恒原理和动量定理,建立了裸眼完井和射孔完井方式下蛇曲井生产井段的井筒压降预测模型。在定产量和定井底流压两种工作制度下,给出了蛇曲井生产井段的压降预测方法。应用所建预测模型和水平井的水平段压降计算模型分别计算了某裸眼完井蛇曲井生产井段的井筒压降,结果表明:蛇曲井生产井段井筒压降不能用常规水平井水平段的压降模型计算,蛇曲井生产井段井筒压降不能忽略。
