基于同一平台的声电测井模拟系统设计与研究

选取不同的声波速度分布范围的红砂岩、黄砂岩、大理石、花岗岩为主要介质,设计研究等比例缩小模型井。由声波探头、脉冲信号发生器、示波器以及频谱分析仪等设备就组成一套完整的岩石声学测井模拟系统,研制等比例缩小普通电阻率、双侧向模拟测井仪,在同一模拟井系统和测量测控平台进行岩石电阻率测井、声波测井模拟实验。

Design and research of acoustic and electric simulation system of well logging based on the same platform

The uniform miniature model well with equal proportion is designed and developed and the red sandstone, the yellow sandstone, the marble and the granite with different acoustic velocity distribution are taken as main media. An integrated acoustic log simulation system is developed, which mainly consists of the acoustic probe, pulse signal generator, oscilloscope, spectrum analyzer and other equipments. The uniform miniature ordinary resistivity log tool and dual lateral tool are developed too. These uniform miniature tools are used for the simulation experiment of the resistivity and acoustic log, which are carried out with the same measurement and control platform in the analog well system.
