在测定含油岩石的各项物性参数之前，必须将岩石孔隙空间中的有机物质抽洗干净。我们根据溶解速度随温度、压力升高而加快的原理，设计制造了一台快速密闭洗油装置，经大量的实验数据对比，本装置具有洗油速度快、无气味、无明火加热，以及自动控制压力和温度的特点。 Before measuring the physical parameters of the oil-bearing rock, the organic matter in the rock pore space must be drained cleanly. Based on the principle that dissolution speed is accelerated with temperature and pressure, we design and manufacture a fast closed oil washing device. Compared with a large amount of experimental data, this device has the advantages of fast washing speed, no smell, no open flame heating, Control pressure and temperature characteristics.
