摘　　要：介绍适于EILog快测平台的阵列感应测井仪MIT1530的系统设计和关键技术。与常规阵列感应相比,MIT1530进行了多方面优化。通过对线圈系参数与结构优化、高性能集成电路选用、工作模式优化、厚膜集成与一体化设计以及实时合成等技术,在保证仪器纵向分辨率和径向探测深度不变的基础上,仪器长度由原来9.86m缩短到4.96m,测量精度由原来±1mS/m提高到±0.5mS/m。仪器现场对比试验表明,仪器稳定可靠,可操作性、易维护性大大提高,测量指标满足现场应用要求。The system design and key technology of MIT1530 for EILog platfrom express are introduced. Comparing with the conventional multi-array induction, the MIT1530 logging tool has carried on the various technology optimization, such as the coil parameters and structure optimization, high performance integrated circuit selection, operation mode optimization, thick film integrated, real-time synthesis, and so on. Based on ensuring the constant vertical resolution and radial depth of instrument, the instrument length is shortened from 9. 86 m to 4. 96 m, measurement precision is increased from the original ±1 mS/m to ±0. 5 mS/m. The field test indicates that the instrument is stable and reliable, its operability and maintainability are greatly improved. The measurement indexes meet the application requirements.
