页岩气藏多段压裂水平井产气贡献度的确定方法
|
摘要
页岩气因为储量丰厚、开采前景很大而在当今的世界能源中举足轻重。长期以来,页岩气产能的理论研究是随着页岩气的生产实践而不断发展、深入的。通过积极查找相关资料多方对比,发现产气剖面测试法可以认识水平井流态分布规律;求取分层产量,优选穿层;优化分段压裂参数;优化井身轨迹;指导生产。本文研究多因素对多段压裂水平井每段的产量贡献度影响,最后构建出在考虑静态因素与工程因素的经验拟合曲线图版,能够使现场工程师直接做出预判。
Shale gas occupies a significant part in the world of energy because of its rich reserves and great exploitation and development potential. Besides, along with long-term development, the theoretical research on the productivity of shale gas is deepened continuously.It is found that the gas flow profile test method can know the distribution law of horizontal well flow, find the stratified yield, optimize the fracturing parameters, optimize the well trajectory, and guide the production. In this paper, the influence of some factors on the yield contribution of each stage of fractured horizontal well was studied. Finally empirical fitting curve chart was constructed through considering static factors and engineering factors.
