Technical field
The utility model relates to oil field CO
2geological storage and displacement of reservoir oil environmental monitoring technology field, be specifically related to CO
2the sampler that geological storage and displacement of reservoir oil SOIL GAS are monitored.
Background technology
CO
2geological storage and the displacement of reservoir oil are by liquid CO
2injected the oil reservoir with good cap rock by gas injection well, a part is sealed in reservoir, and a part enters seepage channel, and the crude oil in displacement reservoir enters producing well pit shaft, is sucked into ground.Preserve cap rock can ensure CO good
2gas can not alter ease to earth's surface, and intact casing string can prevent from causing CO because self damages
2enter in surface soil.But, because strata condition is complicated, under external influence, the change of stress can be there is, cause cap rock be subjected to displacement and cannot CO be sealed up for safekeeping
2, sleeve pipe tubing string is at CO
2the weak acid formed with water effect is damaged under corroding, and these all likely cause CO
2enter surface soil, and pollute.Therefore, CO is detected in time
2content seems particularly important.
Summary of the invention
The utility model is intended to propose one and realizes sample point and fix for a long time, the CO of good leak tightness
2the sampler that geological storage and displacement of reservoir oil SOIL GAS are monitored.
