Oil-gas-water three-phase separating interface controller

Abstract

The invention provides an oil-gas-water three-phase separating interface controller. The oil-gas-water three-phase separating interface controller is that an oil level height control section is arranged on a vertical control pipe; a plurality of water outlet holes of different height are formed in the oil level height control section; a sliding barrel slides up and down at the oil level height control section; a water outlet is selectively communicated with the water outlet hole of different height, and the rest water outlet holes are always kept at the state that the sliding barrel is sealed; or a control valve is arranged on each water outlet hole, and each water outlet hole is communicated with a water outlet pipe through the control valve; a gas chamber and a gas phase section are both sealed and communicated through a communicating pipe; or the gas chamber and the gas phase section are both communicated with the atmosphere. With the adoption of the oil-gas-water three-phase separating interface controller, the liquid level of a storage tank can be accurately effectively controlled, and thereby the labor intensity of staffs at site can be lowered down, the safety risk is reduced, the oil-gas-water three-phase proportional change in the storage tank can be accurately calculated, the time of an oil level stopping in the tank is prolonged, the water content of the oil level is fully decreased, and an important effect is shown on guiding the economic and efficient management of storage and transportation of an oilfield.

Description

technical field [0001] The invention relates to the technical field of oil and gas processing, storage and transportation, in particular to an oil, gas and water three-phase separation interface controller. Background technique [0002] During the processing, storage and transportation of oil reservoir production fluid on the ground, it is often necessary to buffer and store in storage tanks. Storage tanks mainly play the role of storage and three-phase separation of oil, gas and water. Due to the invisible structural obstacles of storage tanks, it is impossible to Accurately knowing the interface of the oil-gas-water three-phase medium in the storage tank makes it impossible to accurately measure the oil production and water production of the oil well, and even cause serious "tank pollution" accidents. A new technology is urgently needed to change this situation. Contents of the invention [0003] The object of the present invention is to design a novel oil-gas-water thre...

[0002] During the processing, storage and transportation of oil reservoir production fluid on the ground, it is often necessary to buffer and store in storage tanks. Storage tanks mainly play the role of storage and three-phase separation of oil, gas and water. Due to the invisible structural obstacles of storage tanks, it is impossible to Accurately know the interface of the oil-gas-water three-phase medium in the storage tank, so that it is impossible to accurately carry out related oil production and water production calculations, and even cause serious "tank pollution" accidents. A new technology is urgently needed to change this situation
