Technical Field

The utility model relates to a gas, oil, separation of water processing technology field, in particular to controllable gas-oil-water three-phase separator of high-efficient temperature.

Background

In the process of producing petroleum, oil gas and formation water are produced simultaneously, so that oil and water need to be separated, and the three-phase separator is widely applied to the petroleum industry and is a device mainly used for controlling the stability of crude oil and the dehydration effect of the crude oil. The three-phase separator used in oil field is a large mechanical equipment capable of respectively separating and metering oil, gas and water, mainly uses the principle of centrifugal force and gravity settling separation to implement gas-liquid separation, and the oil and water are separated under the catalysis of medicine and proper temp. The rest is the process of oil-water separation: the oil-water mixture enters the interior of the three-phase separator, is primarily separated in the pre-separation chamber, and is formed into an oil-water layer in the settling chamber. In order to maintain a stable and controllable oil-water separation interface, the height of the water guide pipe needs to be continuously regulated and controlled according to actual conditions. Finally, the oil-water successful separation is realized, and at present, a horizontal three-phase separator is generally adopted to treat the wastewater so as to realize the separation of three phases of gas, oil and water. The separator consists of a tank body, a feed inlet and an exhaust hole which are arranged at the top of the tank body, a drain hole and an oil discharge hole which are arranged at the bottom of the tank body and a baffle which is vertically arranged in the tank body, wherein the drain hole and the oil discharge hole are positioned at two sides of the baffle, and the baffle divides the tank body into a separation chamber, an air chamber and an oil chamber. The existing oil-water separation baffle structure enables oil to be positioned at the upper part of a separation chamber and water to be positioned at the lower part of the separation chamber, when the oil surface of the separation chamber exceeds the top of the baffle, the oil turns over the baffle, enters an oil chamber and is discharged from an oil discharge hole; and the water at the lower part of the separation chamber is discharged through the drain hole, and the demulsifier mainly has the functions of helping to destroy an oil-water interface film, relieving the coalescence resistance of liquid drops and promoting the oil-water separation process. The separation temperature directly influences whether the water content of the separated crude oil reaches the standard or not, the temperature influences whether the demulsifier can exert the maximum drug effect or not, the demulsifier depends on the temperature, the higher the temperature is, the higher the demulsification efficiency is, and the temperature also influences the viscosity of the crude oil and the dehydration speed, and the prior art has the following problems that 1, the separated gas is mainly primary filtration, and the gas contains oil mist, so that the gas purity is insufficient. 2 the oil-water temperature inside the tank body is not controllable, and the effect of the demulsifier cannot be fully exerted, so that the oil-water separation effect is poor.
