摘要
大牛地气田储层具有低压、低渗、低孔及薄层的特征,水平井是比较有效的提高单井产量、改善开发效果、提高采收率的技术措施,近年来水平井数量逐年增加,但水平井在渗透面积、渗流机理、气液两相流理论方面不同于垂直井,排液方法具有独特的特点,通过现场数据对比找到适合大牛地气田的水平井排液方法。
Daniudi reservoir with low pressure,low permeability,low porosity and the characteristics of thin,horizontal well is more effective to improve well production and improve performance,enhanced oil recovery technology measures the number of horizontal wells in recent years increased year by year,but the level of infiltration wells in the area,flow mechanism,gas-liquid two-phase flow theory is different from the vertical wells,liquid discharge method has unique characteristics,by comparing the field data for a large gas field found in horizontal wells drain method.
