The process can be showed using the Penn State microxidation test designed toevaluate oxidation stability of lubricant. Analyzing the composition of oil samples oxidized,the relation between the formation of deposit and oxidizing time and temperature is gotten.The results show that it is necessary for the temperature at any point in the reactor beingbelow 300℃ and keeping enough steam in the reaction system to ensure vaporization ofhydrocarbons to avoid deposit formation.

利用时间序列分析方法对不同固井质量条件下的超声回波信号进行了分析与识别。根据采用自回归(AR)模型和自回归滑动平均(ARMA)模型对实际回波序列的拟合结果可见,AR模型参数对随机干扰比较敏感,不利于模式分类;ARMA模型参数分布稳定,分类能力强,尤其是自回归系数a3、能准确地将固井模式分为两大类:一类是两界面(套管与水泥间,水泥与地层间)胶结都好或者都坏;一类是两界胶结一好一坏。因此在第一界面的胶结状态确定以后,利用它识别第二界面的胶结状态具有特别重要的意义。

The design considerations and features of the data acquisition and control system of QGZ-A Cement Bond Logging Tool are described in this paper. It can be used for high speed data acquisition of acoustic full wave train, Gamma Ray and casing collar signals so as to determine the cement bond quality between the casing and the cement annulus and between the cement annulus and the formation. A simulation system for the recorded logging signals is also included. This system can be easily expanded. so it can also be used as an interface of the other logging tools for both open hole and cased hole.

肖炜,法林,杨焕成,牟轩沁等.全波固井质量测井仪数据采集与控制系统的电路设计.测井技术,1994,18(5);384~388本文叙述了最近研制的QGZ-A全波固井质量测井仪的数据采集与控制系统的电路设计思想和特点。这个计算机的接口电路可以对石油测井中探测到的声波全波列、自然伽玛和套管接箍信号进行高速数据采集,以判断套管井一次界面和二次界面的水泥胶结质量。它还具有一个测井记录信号的仿真系统,扩展功能强,稍加改进,就可成为裸眼井和套管井其它测井仪的数据采集与控制系统的计算机接口。
