DDL - 水泥胶结测井仪与国产 SKH2 0 0 0数控测井仪地面系统挂接过程中存在井下仪供电电源不同、CCL信号接收传输方式不同以及地面系统对信号的处理等技术问题。首先对国产 SKH2 0 0 0数控测井仪地面系统进行改进 ,以适应DDL - 组合井下仪的供电要求 ;对 DDL - 组合井下仪配接一信号分离转接头 ,以完成 CCL信号的分离 ,满足 SKH2 0 0 0地面系统对信号处理的要求。通过室内配接及现场测井所获资料对比说明了其资料的真实性。这套挂接方法对其它油田国产数控测井仪与 DDL - 水泥胶结测井仪的挂接有一定的参考价值。
DDL - cement cemented logging tool and the domestic SKH2000 CNC logging system surface mount system there are different power supply downhole instrument, CCL signal reception and transmission of different ways and terrestrial system signal processing and other technical issues. Firstly, the ground system of domestic SKH2000 numerical control logging instrument is improved to meet the power supply requirements of DDL - combined downhole instrument. A DDL - composite downhole instrument is connected with a signal separation adapter to complete the separation of CCL signals and meet the requirements of SKH2 0 0 0 ground system for signal processing requirements. Through the indoor matching and field logging data obtained by comparing the authenticity of its information. This method of attachment has certain reference value for the connection between domestic oilfield numerical control logging tools and DDL - cement cementing logging tools.
