测井复查老井油气层实例
|
摘要
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、中原、冀东油田注重断块油藏的油气层复查工作，充分利用计算机处理解释、数控测井、新一代碳氧比能谱测井、双时差重叠、重复式电缆地层测试器、微差识图等新技术。大港油田除注重断块油气藏的复查外，还狠抓射孔试油作业。辽河油田重点集中浅层复查，采用测井与地震相结合的解释技术，也获得明显效果。我国陆上油田约有５０００口老井未获工业油气流，应用测井技术复查老井油气层大有可为。
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.
