Experiment system for water reciprocating movement law of water drive oil and gas reservoir type gas storage

Abstract

An experiment system for a water reciprocating movement law of a water drive oil and gas reservoir type gas storage comprises a water container, a displacement metering pump, a gas booster pump, a gas storage core model, a fluid flowmeter and a control analysis device, wherein the water container comprises a cavity and a piston; the piston divides the cavity into a first cavity body and a second cavity body; pressure between the first cavity body and the second cavity body keeps balanced; the displacement metering pump is connected with the first cavity body and used for quantitatively adding water into the water container; the gas booster pump is connected with the second cavity body and used for quantitatively inflating the water container with gas; the gas storage core model is connected with the first cavity body and used for simulating operation conditions of the gas storage in the reciprocating injection-recovery process; the fluid flowmeter is connected with the first cavity body and the gas storage core model and used for collecting the movement amount of water which flows into or is drained into the first cavity body; the control analysis device is used for controlling the experiment system to simulate the actual injection-recovery process of the gas storage and recording various experiment data. By collecting the experiment data in the injection-recovery operating process, a research basis is provided for analyzing the water movement law in the actual gas storage building and injection-recovery operating process.

technical field [0001] The invention relates to the technical field of oil and gas reservoir-type gas storage, in particular to an experimental system for simulating the law of reciprocating movement of water body during the periodic injection-production operation of the water-flooding oil-gas reservoir-type gas storage in a laboratory. Background technique [0002] The water drive oil and gas reservoir type underground gas storage is a gas storage rebuilt from the oil and gas reservoir with depleted edge and bottom water. Therefore, before the construction of the gas storage, it is necessary to fully understand the original physical properties of the oil and gas reservoir, and study The production operation mechanism and its main influencing factors, especially the impact of water flooding on the injection-production operation indicators of the gas storage during the water body migration process, are used to guide the evaluation of storage capacity parameters and the optimiz...
