Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing:

[0023] Depend on Figure 1 to Figure 10 As shown, a multi-cycle alternating stress fault simulation experiment device mainly includes a core preparation system, a vacuum component, a host model system, a data acquisition and analysis system, and a pressure injection system. The core sample is produced through the core preparation system and the vacuum component. , put it into the host model system, the pressure injection system and other auxiliary systems simulate different formation conditions for experiments, and then the data acquisition and analysis system collects signals and analyzes them by computer to evaluate the sealing performance of the core under different formation conditions.

[0024] The core preparation system includes a core drilling machine and a core cutting machine, and the core drilling machine includes a drilling platform 140, a coring bit 137 fixed o...

Abstract

The invention relates to a simulation experiment device for a fault with multi-period alternating stress, and mainly solves a problem of low possibility of judging fault sealing property of an existing underground gas storage. The simulation experiment device is characterized by comprising a core preparation system, a vacuumizing assembly, a host model system, a data collection and analysis system and a pressure injection system. The device can not only test sealing property parameters of a fault sample of the storage but also realize simulation of a stress state and the like of the sample of the storage under a multi-period alternating stress condition for real-time continuous monitoring, and further can perform comprehensive evaluation on sealing conditions of the fault of the storage under the multi-period alternating stress operation condition in combination with other geological conditions (such as lithologic characters, fault fillers, fault parameters and the like) of the storage.

Description

technical field [0001] The invention relates to a simulation experiment device used by scientific research institutes in the field of oil and gas field development, in particular to a multi-period alternating stress fault simulation experiment device. Background technique [0002] The multi-cycle alternating stress will be formed in the process of multiple injection and production of underground gas storage. Under this condition, the sealability of faults will change. Fault sealability refers to the ability of faults to seal oil and gas, and the migration of faults to oil and gas. The essence of control, accumulation, preservation, and destruction is the problem of fault sealing, which is of great practical significance in the field of oil exploration and development. The failure of the fault sealing of the gas storage will lead to leakage or even failure of the gas storage. Therefore, how to determine and evaluate the upper and lower limits of injection-production pressure ...
