Abstract

The invention provides a core clamper and a core reverse osmosis experiment device. The core clamper comprises a rubber bucket for covering the core, a plurality of electrodes for measuring core resistivity, a cylinder, a sealing sleeve, a front cover, a rear cover, a front plug, and a rear plug. The rear plug is fixedly connected to the rear cover, and is provided with a displacement production pipeline penetrating the resist end of the rear plug. A conical inner concave surface is formed on the end face of the resist end which resists against the core at the front plug, and a circulating injection pipeline and a circulating production pipeline which are parallel to each other and penetrate to the resist end of the front plug are formed at the front plug. A bracket is fixed on the front cover, and is provided with a spiral adjusting component coaxial with the front plug. According to core clamper and the core reverse osmosis experiment device, the problem of the reverse osmosis measurement of the end face of the core can be well solved, the amount of oil production or water production of the reverse osmosis of the end face at different times can be measured, and meanwhile, the position of the reverse osmosis front edge can be determined coarsely through the measurement of the resistivity.

Description

technical field [0001] The invention relates to the fields of petroleum exploration and development and reservoir engineering, and relates to a device suitable for measuring the wettability of rock core columns and imbibition experiments, in particular to a rock core holder and a rock core reverse imbibition experiment device. Background technique [0002] At present, among petroleum engineering experimental methods, imbibition experiment is the main method to study reservoir wettability and imbibition displacement process. At present, there are two main measurement methods, weighing method and imbibition bottle measurement method. [0003] like Figure 4 As shown, the weighing method measurement method is: the rock core 91 is suspended on the hanger 93 by the sling 92, the rock core 91 is soaked in the water in the beaker 94, and the weight of the beaker 94 is measured at different times by a balance 95, and then the weight of the beaker 94 is changed. The ratio of the oil-...
