Abstract

The embodiment of the invention provides a pressurizing constant temperature control device and a core test system. The core test system comprises a CT (computerized tomography) scanner (1), a core holder (2), an injection pump (3), and the pressurizing constant temperature control device (4). The pressurizing constant temperature control device (4) comprises a motor (410), a gear set (420), a first circulating pump (431), a second circulating pump (432), a first temperature sensor (491), a second temperature sensor (492), a temperature control device (440), one-way valves (451-454), and an annular pressure pump (470). The two circulating pumps with opposite operational directions are used as a double power device, so that the problem that baking ovens and like products cannot be used to perform constant temperature control to core flooding experiments using the CT scanner in the prior art is solved.

Description

technical field [0001] The present invention relates to a rock core displacement experiment, in particular to a control device in the rock core displacement experiment, specifically a pressure constant temperature control device and a rock core testing system. Background technique [0002] In the process of oil development, it is often necessary to carry out indoor core displacement experiments to evaluate the oil displacement effect and fluid properties. In the early 1980s, Vinegar and others introduced CT scanning technology into the petroleum industry for the first time to carry out research on reservoir physics and other aspects. After that, CT technology has developed rapidly and has been widely used as a routine testing technology in core analysis. In core description, core heterogeneity determination, determination of core sample processing procedures, quantitative analysis of fractures, online saturation measurement, flow experiment research, etc. Using CT scanning ...
