Description

Carbon dioxide flooding injection flow automatic detector

technical field

The utility model relates to the technical field of automatic flow detection, in particular to an automatic flow detection instrument for carbon dioxide flooding and injection.

Background technique

The greenhouse gas carbon dioxide drives global warming and poses a serious threat to human survival and social and economic development. The most effective way of geological disposal of carbon dioxide is to inject it into oil and gas fields, which not only seals carbon dioxide flooding but also improves the recovery rate of oil and gas fields , and the amount of carbon dioxide flooding injected into the oil and gas field will affect the oil flooding effect of the oil and gas field, so it is necessary to detect the injection flow rate of carbon dioxide flooding.

The Chinese patent discloses an automatic detector for carbon dioxide flooding injection flow, the authorized announcement number is CN206386103U. The patent involves a controller, an inner pipe, an outer pipe, a fluid inlet pipe and a fluid outlet pipe. The inner pipe is sleeved inside the outer pipe and the two There is a gap between them, the fluid inlet pipe and the fluid outlet pipe are connected with the inner pipe, the fluid inlet pipe is located on the upper side of the fluid outlet pipe, the upper opening and the lower opening are arranged on the inner pipe wall, and the upper opening and the lower opening are respectively located On the upper side and the lower side of the fluid inlet pipe, the lower opening is provided with a baffle to close the lower opening, a spring is arranged between the baffle and the outer pipe, and a fixed seat is arranged inside the inner pipe for sealing, and the fixed seat is located between the upper opening and the fluid inlet pipe Between them, a hydraulic rod is arranged at the bottom of the fixed seat, and the hydraulic rod is connected with the controller. A piston is arranged on the piston rod of the hydraulic rod, a fluid through hole is arranged on the fixed seat, and a waist wheel flowmeter is arranged on the top of the fixed seat. The utility model facilitates the detection of the injection flow rate of carbon dioxide flooding and facilitates the normal injection of carbon dioxide flooding when no detection is required. However, when the detector injects the flow rate of carbon dioxide flooding, the carbon dioxide flooding enters the gap between the waist wheel flow meter and the fixed seat through the fluid through hole, and then enters the waist wheel cavity through the air inlet along the air intake pipe for flow detection. Then it flows out of the waist wheel flowmeter through the gas outlet, and flows out to the gap between the inner pipe and the outer pipe through the upper opening, then flows into the inner pipe through the lower opening, and finally flows out to the carbon dioxide flooding injection pipe through the fluid outlet pipe. If the gap between the outer tube and the outer tube is too large, the carbon dioxide that has been detected by the waist wheel flowmeter will remain between the inner tube and the outer tube, and the baffle will be closed under the action of the spring, so that the remaining carbon dioxide will remain between the inner tube and the outer tube. The carbon dioxide in between is not normally injected into the carbon dioxide flooding injection pipeline, which will affect the accuracy of the actual carbon dioxide flooding injection flow detection. Therefore, those skilled in the art provide an automatic detector of carbon dioxide flooding injection flow rate to solve the problems raised in the above-mentioned background technology.
