At present , in casing well logging , ultrasonic imaging well logging tool is mainly used in cement bond appraisal and casing inspection , so as to makes intuitionistic and accurate judgment to the well cementation quality and the casing pipe condition 目前,在套管井测井中,超声波成像测井仪主要用于水泥胶结评价和套管检查,以便对固井质量和套管状况作出直观准确的判断。
This paper is a part of scientific research item " coupling of sound and cement bond logging of shipping hermetic cabin and the influence of multi - variable environment simulative hermetic cabin to body " . it mainly studied the measurement and control system of the simulative hermetic cabin to realize the adjustment of temperature , humidity , stress , oxygen , carbon dioxide , vibration and noise etc . and the parts of system design to the hermetic cabin and corresponding have carried on the technology explanation 本论文是“船舶密封舱内的声固耦合和多变量环境对生理功能的影响”科研项目的子课题,主要对模拟密封舱的测控系统进行研究,以实现密封舱对温度、湿度、压力、氧气浓度、 co _ 2浓度、振动和噪声等变量的调节。
Aiming at some occurrent interfering problems during acoustic variable density logging in oil region , for example , some short horizontal linear interference has appeared in the acoustic variable density logging drawing , and combining with the logging principles of cement bond composed logging tools , this paper has analyzed the factors of forming interferences during acoustic variable density logging and the influences for well cementing evaluation , and suggested some methods to judge and solve every interference 摘要针对油区声波变密度测井中出现的干扰问题,例如在声波变密度测井成果图上有短横线干扰,结合水泥胶结组合仪测井原理,分析了声波变密度测井中形成干扰的因素及其对固井评价的影响,提出对各种干扰的判断和解决方法。
