非常规油气田水平井井位优选应用分析

Unconventional oil and gas wells horizontal wells preferred demonstration analysis

苏里格气田属典型的"三低"气田,储层非均质性强,气藏规模小,砂体展布范围及单井控制储量有限.怎样增加单井产量、提高气田采收率,探索有用的开发技术措施成为了可否达成苏里格气田高效开发的要点.实践证明,利用水平井开发苏里格气田是有效解放储层、提高单井产量、提高气田采收率的重要手段,而水平井井位优选是决定水平井部署成败及气田效益开发的核心问题.本文以苏里格气田SW、TQ区块为例,充分利用三维地震资料与综合地质研究相结合的基础上探讨水平井井位优选技术.

The gas is in a typical ＂three lows＂ gas field,strong reservoir heterogeneity,small gas reservoir,sand body distribution range and the single well controlled reserves is limited.How to improve the single well production and improve the gas recovery factor and seek effective means to develop a field in a comprehensive way to achieving the efficient development of the key.Practice proves that the use of horizontal well development of gas is effective in the liberation of reservoir and improve the single well production and an important means to enhance gas recovery,and the horizontal well placement optimization is to determine the core issue of gas field horizontal well deployment success or failure and the benefits of development.Based on gas Sue in a 5 7 block as an example,peach,make full use of 3 d seismic data and comprehensive geological study on the basis of the combination of horizontal well location optimization technology are discussed.
