Overview

   QY-C12 automatic core displacement device is used to carry out the evaluation test experiment of the core by the use of advanced technology and control measures, and on the basis of simulation of formation pressure and temperature conditions, according to the needs of exploration and development research.The change of water saturation in the rock can be measured during the displacement process(gas drive and oil drive water )in the displacement process of a certain formation condition (temperature and pressure).The measurement method is mainly to determine the resistivity value of the core under different water saturation,and the change of the measured value is automatically drawn by the computer software about the relation curve with the resistivity index.
