METHOD FOR REGULATING THE EVACUATION OF PHASES FROM SEPARATOR TANK

總結

The substance of this method: a flow regulator, which is installed in a gas line, is used for maintaining, within set limits, the pressure in the separator tank, so that same exceeds the pressure in a chamber for mixing the liquid and the gas, and a flow regulator located in a liquid line is used for maintaining the level of liquid in the separator tank.The control process is automatic.

技術優勢

This method advantage consists its simplicityand i ndependent of two regulation prossesesin both channels.

技術應用

The method is usable if independent control for both channels is possible.

詳細技術說明

A method for regulating the evacuation of a liquid phase and a gas phase from a wellbore fluid separator tank along two separate measurement channels, and allowing for measuring, as the flows pass, quantitative indicators for the liquid and gas, and subsequently uniting said flows into a single flow for eventually transporting same; wherein, a flow regulator, which is installed in a gas line, is used for maintaining, within set limits, the pressure in the separator tank, so that same exceeds the pressure in a chamber for mixing the liquid and the gas, and a flow regulator located in a liquid line is used for maintaining the level of liquid in the separator tank. The invention allows for effectively maintaining a level of separation of media (liquid/gas) in the separator tank, while simultaneously maintaining, within set limits, the pressure in the separator tank, so that same exceeds the pressure in the chamber for mixing the liquid and the gas.The invention relates to the oil and gas extraction industry, and specifically to the field of oil extraction technology, and can be used for providing the necessary conditions for rapidly determining the contents of main phases and components in an oil-and-gas fluid exiting a well, while measuring, as the flow passes, quantity and indicators of quality.

The invention relates to the oil and gas extraction industry, and specifically to the field of oil extraction technology, and can be used for providing the necessary conditions for rapidly determining the contents of main phases and components in an oil-and-gas fluid exiting a well, while measuring, as the flow passes, quantity and indicators of quality.

The invention allows for effectively maintaining a level of separation of media (liquid/gas) in the separator tank, while simultaneously maintaining, within set limits, the pressure in the separator tank, so that same exceeds the pressure in the chamber for mixing the liquid and the gas;
The invention relates to mechanical engineering, and more particularly to experimental hydraulics, and can be used in test benches for hydraulic testing and testing measuring instruments. A method comprises the following stages: feeding a two-component liquid into a storage tank, the volume of which is sufficient for the formation of mixtures of liquids of the required concentrations in the upper and lower parts of the tank provided that the two-component mixture is pumped at the maximum possible flow rate; drawing liquids from different levels of the storage tank into a closed circulation loop via separate channels; mixing the liquids drawn from different levels of the storage tank, with the ratio of the flow rates being adjusted in order to eliminate the difference between a set ratio of components and the measured ratio of components in the closed loop; and returning the mixed liquids to the storage tank once they have passed through a testing portion of the loop. The invention is characterized by its technical simplicity: it does not require large tanks and powerful mixing devices, and it permits efficient adjustments to the flow rate and the ratio of the components of a mixture.
