【摘要】：铠装承荷探测电缆是目前油田中普遍使用的一种测井电缆，测井电缆的性能指标是影响测井生产质量的重要因素，因此在将其应用到生产使用之前，必须要对其各项特性参数指标做出准确的测试，以保证质量检测部门的检测工作和测井生产的正常进行。本文根据承荷探测电缆国家标准对铠装电缆各项参数的测试方法进行了分析讨论，设计了一套铠装测井电缆各项参数的测试方案。本论文首先对铠装测井电缆的主要测试参数的国际标准及其溯源性进行了讨论，然后设计了测井电缆测试的整体方案，对测试过程进行了分析研究。对测试误差特性及误差的分析处理进行了研究，提出了采用误差概率分布特性检验和卡方检验的方法对测试数据进行检验，保证了测试结果精确度的科学与合理性。最后分别讨论了铠装测井电缆的机械特性和电气特性的测试方法及具体测试方案。其中机械特性测试包括铠装电缆的单位长度自重、密度、拉断力、伸长率和硬度参数的测试，对目前油田铠装测井电缆所使用的拉断力、伸长率和硬度的测试方法及其具体实施方案进行了详细的分析和讨论；对铠装电缆电气参数的测量主要包括电缆基本电气特性参数的测量和电缆动态特性的研究，其中电缆基本电气参数包括电缆的电阻、绝缘特性和耐压特性，电缆的动态特性主要包括电缆的频率响应特性。本文设计了铠装电缆频率特性测试方案，，并利用Multisim软件给出了相关电路图和仿真结果，得到了铠装电缆的幅频特性和相频特性曲线，验证了测试方法的有效性。本论文所设计的铠装电缆测试方案已用于大庆石油工业机械产品质量监督检验站所承担的测井电缆测试项目中，为检验站进行的测试工作提供了测试依据，提高了测试工作效率，保证了测试工作的质量。
[Abstract]:Armored load detection cable is a kind of logging cable widely used in oil field at present. The performance index of logging cable is an important factor affecting logging production quality, so before it is applied to production,It is necessary to make an accurate test of each characteristic parameter index in order to ensure the inspection work of the quality inspection department and the normal well logging production.According to the national standard of load detection cable, this paper analyzes and discusses the testing method of the parameters of armored cable, and designs a set of test scheme for each parameter of armored logging cable.In this paper, the international standards and traceability of the main test parameters of armored logging cable are discussed, then the overall scheme of cable testing is designed, and the testing process is analyzed.The characteristics of test error and the analysis and processing of error are studied. The methods of error probability distribution characteristic test and chi-square test are put forward to verify the test data, which ensures the accuracy of the test results to be scientific and reasonable.Finally, the testing methods and specific test schemes of mechanical and electrical characteristics of armored logging cable are discussed respectively.The testing of mechanical characteristics includes the measurement of unit length weight, density, tensile force, elongation and hardness parameters of the sheathed cable, and the tensile force used for the armored logging cable in the oil field at present.The measuring method of elongation and hardness and its concrete implementation are analyzed and discussed in detail, and the measurement of electrical parameters of sheathed cable mainly includes the measurement of basic electrical characteristic parameters of cable and the study of cable dynamic characteristics.The basic electrical parameters of the cable include the resistance, insulation and voltage resistance of the cable, and the dynamic characteristics of the cable mainly include the frequency response characteristics of the cable.In this paper, the frequency characteristic test scheme of sheathed cable is designed, and the related circuit diagram and simulation result are given by using Multisim software. The amplitude-frequency characteristic and phase frequency characteristic curve of sheathed cable are obtained, and the validity of the test method is verified.The armored cable test scheme designed in this paper has been used in the logging cable test project undertaken by Daqing Petroleum Machinery products quality Supervision and Inspection Station, which provides the test basis for the testing work carried out by the inspection station.The efficiency of test work is improved and the quality of test work is ensured.
