摘要: 气藏开发实践和室内实验研究均表明低渗含水气藏气体渗流存在启动压力现象,研究启动压力梯度的影响因素和变化规律对气藏开发具有重要意义。通过长岩芯多测点气藏物理模拟实验方法,研究了低渗含水砂岩气藏气相启动压力梯度变化规律,对该参数与储层渗透率、含水饱和度进行了相关性分析,建立了低渗含水气藏启动压力梯度计算通式。结合气藏渗流理论,采用建立的启动压力梯度表征方法,针对典型气藏进行应用分析,确定了气井有效动用半径,形成了有效动用半径与储层渗透率和含水饱和度的关系图版,为类似气藏开发早期井网部署以及开发中后期井网加密提供了技术指导。

Abstract: Gas development practices and laboratory experiments show that there is starting pressure phenomenon in gas seepage in low permeability water-bearing gas reservoir. Therefore, it is very important to study the influence factors and change rules of starting pressure gradient in gas reservoir development. Through experimental methods, the change law of starting pressure in gas seepage in low permeability water-bearing gas reservoir was studied, the correlation analysis of this parameter with water saturation and reservoir permeability was carried out, and quantitative characterization method of starting pressure gradient was researched. An applied analysis was carried out on a typical reservoir with the starting pressure gradient calculation method and gas reservoir percolation theory. Effective development radius of wells was calculated, and the relationship of effective development radius with water saturation and reservoir permeability was established. This method provides a technological guidance for the similar gas reservoirs development especially on well pattern deployment in the early period and well pattern infilling in the middle and later periods.

Key words: water-bearing gas reservoir, non-Darcy flow, starting pressure gradient, experiment research, quantitative characterization
