Abstract

The present invention discloses a core clamper constant temperature system and an experiment method thereof. The constant temperature system comprises: a core clamper containing a fluid chamber; a constant pressure pump connected with the inlet of the fluid chamber of the core clamper and used for pressurizing the core clamper; a cooling device, wherein the inlet of the cooling device and the outlet of the fluid chamber of the core clamper are connected and are connected with a switch pipeline in a parallel manner, the cooling device cools the core clamper during the working, and the fluid chamber of the core clamper is communicated with the switch pipeline when the cooling device is in the off-line state; a heating device, wherein the inlet of the heating device is communicated with the outlet of the cooling device and the switch pipeline, and the heating device heats the core clamper through the switch pipeline; and a circulation pump connected between the outlet of the heating device and the inlet of the core clamper so as to form the whole fluid circulation circuit. According to the present invention, the constant temperature system can easily be combined with other devices, and can improve the experiment efficiency.

Description

technical field [0001] The invention relates to an experimental device used in the field of oil and gas field development, in particular to a constant temperature system of a core holder and an experimental method thereof. Background technique [0002] Existing core holders usually rely on air constant temperature baths or electric heating jackets to achieve constant temperature. Using an air constant temperature bath to achieve constant temperature requires an oven, and then put the core holder and related devices into the oven to maintain constant temperature. The use of electric heating jacket to achieve constant temperature is to wrap a layer of heating jacket made of asbestos mesh and resistance wire on the outside of the core holder, and the heat generated by the resistance wire to heat the core holder to achieve constant temperature. [0003] In oil and gas field development tests, the application of non-destructive testing technologies such as nuclear magnetic reson...
