Abstract
The utility model discloses a gas-liquid separator for a submersible electric pump unit. The separator comprises an upper joint and a lower joint, and is characterized in that: an inner sleeve is arranged between the upper joint and the lower joint; a suction port is reserved on the inner sleeve; an imbalance block is arranged at the suction port; a shell is arranged out of the inner sleeve; and the inner sleeve can rotate relative to the shell. In the gas-liquid separator for the submersible electric pump unit, the inner sleeve is arranged between the upper joint and the lower joint; and the inner sleeve is ensured to be downward all the time when rotating to the suction port in a horizontal working state by arranging the imbalance block at the suction port of the inner sleeve; therefore, gas-liquid separation of well fluid in the horizontal state is solved effectively. The gas-liquid separator for the submersible electric pump unit is suitable for a high-temperature (250 DEG C) production well, and simultaneously has the characteristics of simple and reliable structure and convenience for processing.
Description
Technical field
The utility model relates to a kind of gas-liquid separator, relates in particular to a kind of gas-liquid separator that is used for the horizontal Electric Submersible Pump Unit.
Background technology
Electric Submersible Pump Unit is a underground equipment important in the oil mining, mainly comprises submersible electric machine with oil, seal protector, gas-liquid separator, efficient gas processor, oil-immersed pump etc.Gas-liquid separator plays the effect that separates gas in the well liquid in Electric Submersible Pump Unit, and it also directly is in the well liquid, and the quality of its quality and performance directly has influence on the effect of divided gas flow.Existing heavy oil wells adopts artificial lift equipment to exploit, and temperature is up to 200 ℃, and for improving recovery ratio, oil well often adopts the extended horizontal well structure, and the heatproof of lifting equipment is had relatively high expectations, and is higher to the gas-liquid separator performance requirement.And the gas-liquid separator that generally uses at present as operating temperature at the rotary separator below 180 ℃, and its duty is vertical or tilting, is not suitable for horizontal well, when being used for horizontal well, gas-liquid separation effect is very poor.
The utility model content
The purpose of this utility model is to provide a kind of horizontal well and good Electric Submersible Pump Unit gas-liquid separator of gas-liquid separation effect of being applicable to.
The purpose of this utility model is to realize like this, a kind of Electric Submersible Pump Unit gas-liquid separator, comprise top connection and lower contact, it is characterized in that: be provided with inner core between described top connection and the lower contact, described inner core is provided with intake, described intake place is provided with weighting block, and described inner core can rotate with respect to housing, and inner core rotates to intake all the time down when guaranteeing that described Electric Submersible Pump Unit gas-liquid separator is in the horizontal operation state.
Above-mentioned housing is provided with runner.
Above-mentioned inner core is connected with above-mentioned housing by high-temperature bearing.
Above-mentioned inner core is connected with above-mentioned high-temperature bearing by reducing cylinder.
Be provided with anti-wearing liner between above-mentioned upper and lower joint and the rotating shaft.
Be provided with shaft block ring between above-mentioned upper and lower joint and the rotating shaft.
Be provided with locating shim between above-mentioned upper and lower joint and the rotating shaft.
Above-mentioned top connection is connected with connector.
The lower end of above-mentioned Electric Submersible Pump Unit gas-liquid separator connects the protector part of Electric Submersible Pump Unit, and the upper end connects the efficient gas processor.When it is in the horizontal operation state, inner core rotates under the effect of weighting block that intake is downward all the time, and well liquid is entered in the housing by runner, and the well liquid that density is big sinks to entering inner core from intake, and the little gas of density can not enter intake above being in, thereby realizes Oil-gas Separation.High-temperature bearing can guarantee that inner core rotates flexibly, reaches intake all the time down under the condition of high temperature.
The utlity model has following beneficial effect, the utility model is provided with inner core between top connection and lower contact, inner core rotates to intake all the time down when weighting block being set guaranteeing the horizontal operation state by the intake place at inner core, effectively solved the go into the well gas-liquid separation of liquid of level, and be applicable to high temperature (250 ℃) producing well, have characteristics simple and reliable for structure, easy to process simultaneously.
