Abstract
The gas hydrate reservoir has the problems of weak consolidation, shallow burial and difficult seepage, and is accompanied by complex phase and temperature changes during the development process. Therefore, the sand production problem in the development of gas hydrate reservoir seriously restricts its commercial development, and the sand control research in the development of gas hydrate is particularly important. Therefore, it is the basis of long-term safe and efficient development of hydrate to clarify the plugging rule of argillaceous silt in the sand control medium of hydrate reservoir. Therefore, this paper designed a set of visual simulation experiment device for sand control and plugging prevention, which simulated the sand control process of screen media. The results show that the precision of sand control is the key factor affecting the development of hydrate. The precision of sand control is too high, dense mud cake is formed on the surface of the medium, and the plugging is serious, which increases the resistance of fluid flowing from the hydrate reservoir to the wellbore, thus reducing the production of natural gas; If the sand control accuracy is too low, a loose sand bridge will be formed on the surface of the sand control medium. The sand control ability of the medium is poor and the sand production is serious; Due to the low temperature and high pressure characteristics of the reservoir, gas water fluid may adhere to the surface of the medium, increasing the degree of plugging of the medium. The research results have certain guiding significance for sand control in the process of hydrate exploitation.
