注钆中子寿命测井工艺及解释方法研究应用

1 Process and Interpretation Method of Gadolinium Injectine Neutron Lifetime Logging and Its Application

针对中原油田不同区块的井况及地质特征,研究了不同井况及区块的注钆中子寿命测井施工工艺,讨论了相应的定性和定量解释方法。在不同的区块要建立不同的解释图版。应用效果分析表明,利用注钆中子寿命测井工艺及解释结果可以寻找潜力层,为增产挖潜提供依据,找出水层,为卡水堵水措施提供依据。

In view of the well conditions and geologic characteristics in different blocks of Zhongyuan Oilfield, operational process of gadolinium injecting neutron lifetime logging in different conditions and different blocks is studied. Related qualitative and quantitative explanation methods are discussed. Different interpreting chartboards are developed for different blocks. Application results show that potential zones would be found out by using the process of gadolinium injecting neutron lifetime logging and its interpreting result so as to provide bases for increasing production and tapping the potential, and search out water layer to provide bases for taking measures to eliminate water block off.
