Title:
EVALUATION DEVICE FOR HYDRATE-CONTAINING RESERVOIR DAMAGE AND EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/124661
Kind Code:
A1
Abstract:
An evaluation device for hydrate-containing reservoir damage, comprising: a sample synthesis chamber (10), used for synthesizing a hydrate-containing reservoir; a stress-strain system, used for providing overlying stress and pore pressure to the sample synthesis chamber and measuring the pressure and strain of the reservoir; a temperature system, used for performing temperature control on the sample synthesis chamber and measuring the temperature of the reservoir; a gas-liquid-solid separation system, used for performing gas-liquid or gas-liquid-solid separation on the output of the sample synthesis chamber and measuring the output; a data acquisition and monitoring system, used for acquiring real-time data and performing real-time image acquisition on the gas-liquid-solid separation system. The device can synthesize a specific hydrate sample under overlying stress, and monitor the temperature, pressure and strain during the synthesis process; a sensitivity test can be performed on a specific hydrate-containing sample, and the sensitivity thereof and damage of a working fluid to the reservoir can be evaluated.
