摘要: 国内外对于水平井单井技术经济界限的研究相对较少, 缺乏系统而实用的确定方法。依据水平井开发的现场实际情况, 通过对水平井单井产量变化规律的分析, 以及非线性盈亏平衡原理, 推导出水平井投产初期的单井产量和水平井控制地质储量的经济界限计算方程。将该方程与水平井产量预测公式和水平井控制地质储量公式相结合, 不仅可以判别采用水平井进行开发是否具有经济效益, 而且可以应用于水平井开发优化设计, 因此该方法对于指导油田有效开发具有重要的理论和实践价值。

关键词: 水平井, 产量递减, 技术经济指标

Abstract: Based on real situation of horizontal well development at home and abroad, the variation of horizontal well production is analyzed. And the deduced equations of economic limitation for both well production and OOIP controlled by horizontal wells in early stage of such a development. These equations can be integrated and used to distinguish the economic benefit by horizontal drilling process and make an optimized design of it.

Key words: horizontal well, production decline, technical and economic index
