CJ40-D型套损检测测井仪的应用

On CJ40-D Casing Damage Logger and Its Application

为了解决涪陵页岩气井套损检测测井难题,在众多同类测井仪中,基于性价比和检测套管壁厚、内径变化,直观反映管壁变形、孔洞、裂缝、腐蚀的具体位置和现今形态要求,优选了CJ40-D型仪器进行测井试验。通过江汉油田和涪陵页岩气田多井应用试验,结果表明,CJ40-D型套损测井仪能够有效进行油气井套损检测,效果良好,完全可以满足涪陵页岩气井套损检测需要,实践经验值得国内同行借鉴。

CJ40-D casing damage logger is optimized as the solution to the difficulty in casing damage inspection in Fuling shale gas wells rather than the other similar loggers due to its good cost performance, effective detection of casing thickness and inner--diameter change and direct reflection of specific location of casing wall deformation, fracture and corrosion. Its application in many wells in Jianghan Oilfield and Fuling Shale Gas Field shows that it is better at casing damage detection of oil and gas wells and can satisfy enough Fuling shale gas well in casing damage detection, shedding new light oa the other oil and gas fields.
