摘　　要：为了提高中晚期油田开发效益,设计了基于激发极化和自然电位原理的多参数地层水测井仪发射机。针对井下高温高压和空间狭小的环境特点,采用了模块化的设计思想,并使用数字化的互连方式,实现了发射机的灵活控制。重点阐述了系统硬件电路及软件的设计方法。与测井仪联调的测试结果表明,该发射机可以在常温到150℃温度范围内稳定可靠地工作,具有良好的实时性与准确性。In order to improve the benefit of the middle-late oilfield development,the multi-parameter formation water logging instrument transmitter based on the principle of induced polarization and spontaneous potential was designed. According to the envi- ronmental features of high temperature, high pressure and narrow space underground, the modularized design idea was adopted, and the digital intereonnection method was used, thus the flexible transmitter control was realized. This paper focused on the method of the system hardware and software design. The test results with the logging instrument show that the transmitter is able to work stead- ily and reliably below 150 ℃ ,and both real-time and accuracy are good.
