摘　　要：采用存储式电子测井仪器实现油气井井下参数测量,需要其具有大的存储容量.然而受到高温、高压环境限制,一般高温存储器由于存储器件选择范围较窄且单个器件存储容量较小,使其存储容量难以满足井下数据存储要求.设计了一种采用支持I2C总线EEPROM构成的存储器阵列的解决方案,使其存储容量达到16 MB,并给出了存储器阵列的电路设计,讨论了存储器阵列数据的读写操作问题.油气井压裂过程井下测试试验表明,采用该存储器阵列的井下电子压力计可满足井下工作环境和数据存储的要求,这种设计方法也可进一步应用于其他存储式测井仪器.Memory electronic down-hole logging instrument needs great data storage capacity.But under the conditions of high down-hole pressure and temperature,the data storage devices that can be selected are a little,and the data storage capacity of single device is small.In order to solve these difficulties,a kind of memory array is designed for the electronic down-hole logging instrument.It is constituted by EEPROM supporting I2C bus.The storage capacity memory array can reach to 16 MB.The electronic circuit design of this memory array s presented and its read and write operation is discussed.Its application to downhole electronic pressure gauge shows that this memory array can meet the down-hole conditions and the requirement of the pressure gauge to data storage capacity.This kind of memory array may also be applied to other down-hole electronic logging instrument.
