三塘湖盆地火山岩油气藏录井评价思路与对策

Countermeasures and Ideas on Logging Evaluation of Volcanic Hydrocarbon Reservoir in Santanghu Basin

三塘湖盆地石炭系、二叠系火山岩岩性复杂,油质类型丰富,造成油气水评价困难。为提高录井岩性剖面符合率与油气解释符合率,发挥录井技术油气定量检测之优势,通过对该地区近年录井实践总结,提出了合理的录井技术配套对策,并形成了现场录井与测井曲线响应特征相结合鉴别火山岩岩性的方法,确定了录测井综合评价油气层的技术思路。

Complicated lithology and abundant oil types of Carboniferous and Permian volcanic rocks cause the evaluation of oil and gas and water difficult in Santanghu basin. In order to increase the coincidence rate of logging lithologic profile and oil - gas interpretation and take advantage of oil - gas quantitative examination of logging technique, reasonable matching countermeasures of logging technique are proposed by summarizing the logging practices in recent yeas in this area. The method of combination of field logging and log curve response characteristics to identify volcanic lithology is formed, and the technical ideas using logging and well log to comprehensively evaluate reservoir are determined.
