Isolation Scanner套后成像测井找漏技术在H油田的应用

Application of Isolation Scanner for Leak Finding in H Oilfield

塔里木盆地H油田整体采用超深水平井开发,近年套损现象呈增加趋势。目前常用套损井找漏技术效果不理想。针对该现状提出了Isolation Scanner套后成像测井(IBC)找漏技术,该技术能同时测量套管内径和壁厚变化,定量评价内部腐蚀和外部腐蚀,分辨率高,在H油田H68水平井应用成功,该技术为H油田类似油水井找漏提供了技术指导和实际经验。

The H Oilfield of Tarim Basin was developed by the ultra deep horizontal well.These years,the phenomena of casing injury were increasing,bringing difficulties to the production.The effect of conventional methods of leak finding is not very good.For this state we propose Isolation Scanner technology,which can measure casing inside diameter and change of casing wall thickness,and can quantitatively evaluate inside corruption and outside corruption with high resolution power.Isolation Scanner technology was successfully used in 68 horizontal wells and is useful for finding leak for other casing damage wells.
