我国东部油田已进入成熟勘探阶段，但由于受当时勘探技术条件的限制，使一部分老井尚有大量的油气资源未被发现。随着现代勘探技术的进步，东部油田采用测井技术复查老井油气层，挖掘油田内部油气资源潜力，取得了“增储上产”的显著成果。大庆油田对测井一次解释数据进行了重新核实和校正，采用新研究出的测井解释图版和评价方法，根据裸眼井和套管井的中子伽马曲线进行对比分析，重新评价老井是否存在气层，取得了良好效益。胜利、

SOME EXAMPLES OF CHECKING OLD-WELL HYDROCARBON ZONE BY WELL LOGGING TECHNOLOGY

Well-logging is the most effetive way to check old-well hydrocarbon zone. In recent years, the oil fields in the cast part of China check the old-well hydrocarbon zone by using logging technology and exploit potentialies of hydrocarbon resource in fault block reservoir.the satisfactory result of increasing reserve and production has ben obtained. This paper demonstrates the examples of checking old-well hydrocarbon zone by well-logging in the east pert of China. Reader can draw lessons from these examples.
