摘　　要：基于现有大庆油田井下智能电控存储式油井分层测压仪的电路控制部分进行降低功耗的改进研究。在满足智能电控存储式油井分层测压仪其测压过程中自动坐封及解封控制等功能不变的情况下,对目前单层井下测压仪电控部分进行软硬件改进设计。通过改进后的电控部分,降低了控制电路的功耗,同时为实现长期多层井下测压提供技术支持。Basing on improving circuit control of the downhole hierarchical load cells on hand to reduce power dissipation,both software and hardware design of downhole pressure measurement device with intelligent electronic control storage was improved while the functions like auto-blocking/deblocking works as usual.The improved circuit control with low power dissipation can provide technical support to long-term multi-layer pressure measurement underground.
