| 摘 要： | 川西北部的砂岩储层普遍易受钻井液侵害.为避免钻井液对储层产生污染,采用欠平衡钻井、测井等油气层保护措施.通过Q3井须二地层的钻井、测井实例说明了欠平衡测井对油气层的保护效果非常显著;分析了欠平衡状态下获得的测井资料所受的影响及响应特征、欠平衡测井资料的处理难点以及确定储层评价的方法.

| Abstract: | In the north-west of Sichuan Basin, sandy reservoir is easy invaded by drilling fluid. The under-pressure balance drilling and logging methods are used to protect this reservoir from the drilling fluid pollution. Drilling and logging examples of Xu-2 formation in Well Q-3 proved that the above methods are very effective in protection of oil/gas reservoirs. Analyzed are influence factors on and response characteristics of log data and difficulties in log data processing under the condition of under-pressure balance drilling and logging operations, thereby choosing some useful and reliable reservoir evaluation methods. |

| Keywords: | under-pressure balance drilling under-pressure balance logging low porosity low per- meability oil & gas zone protection reservoir evaluation data interpretation |
