In this paper the model of the thermal conduction between the wellhole and the formation was developed after considering the effects of the heat conduction and the heat convection on the basis of the law of conservation of energy, then the temperature distribution varied with the depth of the interior and the exterior of the drilling pipe was calculated during the gas drilling, which provides the accurate basic data for exact calculation of the temperature distribution of the wellhole.

本文根据能量守恒定律，考虑热传导、热对流的影响，建立了井筒和地层之间的热传递模型，计算了气体钻井过程中管柱内外沿井深的温度分布，为气体钻井计算井筒压力分布提供了准确的基础数据。

But in practical application, the results of calculation usually have a greater difference from reality, which are mainly the following several points: it is thought that single-phase to flow for fluid in the formula, and multiphase flow exists actually; also the impact of the pressure drop in horizontal section and the wellhole completion forms on the deliverability are not included, as well as the bottom water coning is a complex question affecting well deliverability.

但在实际应用中，计算结果与实际往往存在较大的差别，其原因是：公式推导中假设流体流动是单相流动，而实际地层往往是油水两相流动；公式中没有考虑水平井筒内压降的影响；不同的完井方式所对应的表皮系数不同，对产能影响也较大。

The flow resistance and the phase permeability and the coupling of the flow between the reservoir and the wellhole were adopted to admend the deliverability equations of the horizontal well, which improves the applicability of the formula and the adjusted deliverability equations can guide and serve in the fields production with the the horizontal well.

本文以评价边底水油藏水平井产能及影响因素为总体目标，在国内外文献调研基础上，采用镜像反映原理和势的叠加理论推导出边底水油藏水平井产能公式，然后考虑完井、多相渗流及井筒压降对产能的影响，提出了利用流动阻力、相渗透率及井筒与油藏流动耦合修正水平井产能的修正方法，提高预测公式的适用性，为边底水油藏水平井生产提供了指导作用。
