通过应用大庆徐深气田开发取得的矿场资料,分析了火山岩气藏的产能特征。论述了其影响因素。火山岩气藏主要表现为井间产能及井控动态储量差异大、气井动态特征及稳产能力各不相同。受裂缝水窜的影响出水、常规评价技术对产能适应性差。同时也指出储层的物性、井控流动区域形态与物性差异、连通的高渗带(体)的规模、储层微观渗流特性等是气井产能的主要影响因素。这些结论和认识对火山岩气藏的开发具有重要指导意义。
The production characteristics of volcanic gas reservoirs are analyzed by applying the mine data obtained from the development of the Daqing Xushen gas field. Discusses its influencing factors. Volcanic gas reservoirs are mainly manifested in large differences in well productivity and well control dynamic reserves, dynamic characteristics and stable capacity of gas wells. Affected by the fissure water channeling effluent, conventional evaluation of the poor adaptability to production capacity. At the same time, it also points out the physical properties of reservoirs, the differences of the morphology and physical properties of well-controlled flow areas, the size of interconnected hypertonic zones and the microscopic seepage characteristics of reservoirs are the main influencing factors of gas well productivity. These conclusions and understanding have important guiding significance for the development of volcanic gas reservoirs.
