Embodiment Construction
[0058] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, but not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.
[0059] Considering the existing core detection devices, most of them first simulate the stratum environment through one-dimensional simulation under normal temperature conditions, and then use conventional detection methods to count the distribution of target objects in the core samples under the stratum environment. As a result, it is im...

The embodiment of the invention provides a device and method for migration-accumulation visual detection of high-temperature and high-pressure natural gas, wherein the device comprises a first gas storage tank, a first container, a rock core holder, a nuclear magnetic resonance analyzer, a hot box circulating pump, a loop pressure tracking pump, a gas booster pump, and a constant-pressure and constant-flow pump; an inlet end of the rock core holder is provided with two branches: a first branch connected with the first gas storage tank, and a second branch connected with the first container; the hot box circulating pump and the loop pressure tracking pump are connected with the rock core holder; the rock core holder is a non-magnetic rock core holder and is placed in the nuclear magnetic resonance analyzer. The hot box circulating pump, the loop pressure tracking pump, the gas booster pump and the constant-pressure and constant-flow pump are used for accurately simulating high-pressureand high-temperature environment characteristics in stratum, and the distribution state parameters of a target object in a rock core are obtained real-timely by the nuclear magnetic resonance analyzer, so that the technical problems of poor accuracy of detection of migration state the object target in the rock core, complicated operation and low detection efficiency in conventional methods are solved.
Description
technical field [0001] The present application relates to the technical field of oil and gas exploration and development, in particular to a visual detection device and method for high temperature and high pressure natural gas migration and accumulation. Background technique [0002] In the process of oil and gas exploration and development, it is often necessary to detect the migration state of the target in the core samples collected in the target area, and then determine the composition of oil and gas in the target formation according to the migration state of the target in the core sample. According to the specific process of the accumulation mechanism, specific oil and gas exploration can be carried out according to the accumulation mechanism of oil and gas, such as the distribution prediction of oil and gas enrichment; or specific oil and gas production can be carried out according to the process of water flooding oil and gas, such as the design of oil and gas productio...
