Embodiment Construction

[0027] In order to further elaborate the technical means and effects that the present invention adopts for reaching the intended invention purpose, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention are described in detail as follows:

[0028] The idea of ​​this application is: firstly, to solve the problem that the relevant acoustic and electric parameters cannot be accurately tested due to the change of the properties of the hydrate core samples when the hydrate core samples are transferred from high pressure and low temperature to normal pressure conditions; The integrated probe realizes the combined acoustic and electric detection of hydrate core samples and proposes innovative solutions. In particular, a special test system is designed that can not only meet the requirements of rapid joint detection of acoustic and electric characteristics under normal pressure...

Abstract

The invention discloses a test system and a test method for a hydrate core sample, and relates to the technical field of hydrate research. The test system comprises a hydrate core sample preparation module and a core parameters test module. The hydrate core sample preparation module is used for preparing the hydrate core sample in a hydrate core former. The core parameters test module comprises amounting plate, a temperature adjusting jacket arranged on the mounting plate, and a probe slidably arranged on the mounting plate. The hydrate core former is placed inside the temperature adjusting jacket; and the probe is used for measuring the hydrate core sample in the hydrate core former. According to the test system and the test method for the hydrate core sample, the test system has the beneficial effect that the special test system can rapidly carry out the joint detection of the acoustic and the electrical under conditions of normal pressure. The acoustic and electrical parameters ofthe natural gas hydrate core samples can be tested simultaneously, and the acoustic and electrical characteristics of different types of natural gas hydrate core samples can be obtained, by using thetest system and the test method, thereby providing an effective detection basis and a theoretical basis for exploring an actual natural gas hydrate.

Description

technical field [0001] The invention relates to the technical field of hydrate research, in particular to a hydrate core sample testing system and testing method. Background technique [0002] Natural gas hydrate resources have a wide range of distribution, high energy density, and are cleaner than traditional fossil energy sources. They are potential new energy sources in the 21st century. At present, research on the exploration and development of natural gas hydrate resources has attracted the attention of domestic and foreign researchers, and has become an international research hotspot. Acoustic and electrical parameters are very important for natural gas hydrate detection and condition monitoring. Natural gas hydrate simulation laboratories at home and abroad have always paid attention to the simulation experiments of natural gas hydrate acoustic and electrical characteristics. [0003] The ultrasonic measurement of acoustic parameters is to judge the process of hydrat...
