射孔关键参数对水平井产能的影响

Influence of perforation key parameters on horizontal well productivity

以射孔关键参数对水平井产能的影响作为研究对象,首先简单叙述射孔水平井产能数学模型的建立,然后介绍射孔水平井表皮系数计算方法,随后从射孔参数对产能指数的影响、射孔参数对产能比(PR)的影响、油井中机械表皮因子和非达西流对流能指数的影响等维度,详细分析射孔关键参数对水平井产能的影响,旨在为更多油气开发单位提供技术指导,助力我国油气资源生产领域的可持续发展。

Takes the impact of key perforation parameters on the productivity of horizontal wells as the research object.First,it briefly describes the establishment of the mathematical model for the productivity of perforated horizontal wells,and then introduces the calculation method of skin factor of perforated horizontal wells.Then,it discusses the impact of perforation parameters on productivity index,the impact of perforation parameters on productivity ratio(PR),the impact of mechanical skin factor in oil wells and the impact of non Darcy flow on the convective energy index,The detailed analysis of the impact of key perforation parameters on the productivity of horizontal wells aims to provide technical guidance for more oil and gas development units and help the sustainable development of China's oil and gas resources production field.
