摘要
鄂尔多斯盆地苏里格气田储集层为一致密砂岩储层.低阻气层与高阻气层共存,气水关系复杂,气层评价是现场工作面临的主要问题.为快速准确储层评价,将核磁共振录井技术方法应用于现场分析,通过综合分析与参数优选组合,建立研究区含气、含水评价参数及解释模版,有效量化了储集空间流体,现场气藏评价应用效果较好.此技术的成功应用,为致密天然气储层识别与评价提供了新的思路和技术手段.
Sulige gas field of Ordos basin is tight sandstone reservoirs,have low resistance and high resistance gas reservoirs.And gas reservoir evaluation become a key issues in the field work, a single conventional logging tools and interpretation methods are difficult to quickly accurately determine the gas-bearing sand situation. In order to effectively Sulige gas tight gas sandstone reservoirs of recognition, the article discusses the nuclear magnetic resonance in identifying the feasibility of gas, through comprehensive analysis and parameter optimization of combination gas region was established evaluation parameters. Application shows that gas index by the introduction of gas identified in the study area has a good effect.
