摘　　要：中亚KX气田传统目的层是侏罗系气层,KX-21井钻穿侏罗系砂泥岩、钻遇古生代碳酸盐岩,常规测井曲线无法确定古生代碳酸盐岩地层是否含气。在常规测井结束后,加测P型核磁与阵列声波成像测井技术,确定古生代存在好气层。甲方采纳我方建议、加深钻井20米留足口袋,试油获取高产气,在海外新区块成功推广成像测井技术应用。The traditional target zone of KX gas field of Central Asia is in Jurassic,KX-21 well drilled through sandstone and shale in Jurassic and drilled encounter carbonate in Paleozoic,and it is uncertain whether there is gas in Paleozoic carbonate zone only use conventional logging curves.MRIL-P and MPAL were logged after conventional logging was finishd,good gas zones in Paleozoic were identified and certain.The Party A company adopted our advice and drilled 20m more as a pocket to keep enough depth to test the gas zones that were interpreted.Advanced image logging tools were popularized successfully in the new exploration blocks abroad by discovering high-production gas layers.
