Method of operation of mine jet plant at hydrodynamic bed stimulation in process of bottom hole zone treatment

FIELD: oil producing industry. SUBSTANCE: according to proposed method, stem, packer and jet pump installed on tubing string are lowered into well. Packer and jet pump are installed over top of payout bed and releasing of packer is done. Working agent is periodically fed into nozzle of jet pump by means of pumping set. Jet pump operates as follows: first working agent is sharply delivered into nozzle of jet pump at preset pressure of pumping set and required depression of payout bed is created in several seconds. Said depression is maintained during 2 to 20 min by constantly delivering working agent into nozzle of jet pump at preset pressure of pumping set and then hydrostatic pressure of liquid column in well is restored abruptly owing to liquid crossflow into underpacker space and hydraulic shock is generated directed to payout bed side, and particles of coltamont are teared off owing to sharply cutting of delivery of working agent into nozzle of jet pump. Pressure of liquid column is set to exceed formation pressure. Time of action of hydrostatic liquid column onto bottom hole zone is set two-fold less than depression time. Then working agent is sharply fed into nozzle of jet pump and cycle described above is repeated. Number of cycles "depression + restoration of hydrostatic pressure" is determined by degree of restoration of permeability of bottom hole zone of bed by carrying out checks of well production rate before and in process of cyclic action onto bottom hole zone. If output of well remains constant during last two checks, work is stopped.

Ejector-type refrigerant cycle device

Eine Kältemittelkreislaufvorrichtung (10) vom Ejektortyp weist einen Kompressor (11), einen Kühler (12), einen Ejektor (15), einen saugseitigen Verdampfer (18), welcher zum Verdampfen von Kältemittel angeordnet ist, das in einen Kältemittelsauganschluss (15c) von dem Ejektor einzusaugen ist, und einen Auslasskapazitätssteuerabschnitt (20a), der zum Steuern einer Kältemittelauslasskapazität des Kompressors ausgebildet ist, auf. Der Auslasskapazitätssteuerabschnitt erhöht die Kältemittelauslasskapazität des Kompressors entsprechend zu einer Erhöhung von einer Bedarfskapazität, welche in einem Kältemittelkreislauf bei einem allgemeinen Betrieb benötigt wird, wenn die Bedarfskapazität größer ist als ein Standardwert. Im Gegensatz dazu steuert, wenn die Bedarfskapazität, welche in dem Kältemittelkreislauf benötigt wird, gleich ist zu oder geringer ist als der Standardwert, der Auslasskapazitätssteuerabschnitt die Kältemittelauslasskapazität des Kompressors, um abwechselnd zwischen einem Hochkapazitätsbetrieb und einem Niedrigkapazitätsbetrieb geschaltet zu werden. Eine Menge der Zirkulation von Kältemittel in dem Kältemittelkreislauf kann somit in geeigneter Weise eingestellt werden.

Ejector

A body of an ejector includes a diffuser passage, in which an ejection refrigerant jetted from a nozzle passage and a suction refrigerant drawn from a suction passage are mixed together and pressurized by arranging a passage formation member, and a gas-liquid separation space, in which the refrigerant flowing out of the diffuser passage is separated into gas and liquid by the action of a centrifugal force. An inlet part of an oil return passage that is open in the gas-liquid separation space is arranged at a position closer to an outer peripheral side than to an axis center of the passage formation member.

Ejector

An ejector has a swirling space, a pressure reducing space, a suction passage, a pressure increasing space, a nozzle passage, a diffuser passage, a passage forming member that forms the nozzle passage and the diffuser passage, and a vibration suppressing portion that suppresses a vibration of the passage forming member. The vibration suppressing portion has (i) a first elastic member that applies a load to the passage forming member in a direction in which an area of a cross section perpendicular to the direction of the central axis of the nozzle passage and the diffuser passage decreases and (ii) a second elastic member that applies a load to the passage forming member in a direction opposite from the direction in which the first elastic member applies the load to the passage forming member.

Ejector-type refrigerant cycle device

An ejector-type refrigerant cycle device includes a compressor, a radiator, an ejector, a suction side evaporator disposed to evaporate refrigerant to be drawn into a refrigerant suction port of the ejector, and a discharge capacity control portion configured to control a refrigerant discharge capacity of the compressor. The discharge capacity control portion increases the refrigerant discharge capacity of the compressor in accordance with an increase of a requirement capacity required in a refrigerant cycle of a general operation, when the requirement capacity is larger than a standard value. In contrast, when the requirement capacity required in the refrigerant cycle is equal to or smaller than the standard value, the discharge capacity control portion controls the refrigerant discharge capacity of the compressor to be switched alternately between a high capacity operation and a low capacity operation. Thus, a refrigerant circulation amount in the refrigerant cycle can be suitably adjusted.

Torque estimating device for compressor

A torque estimating device of a compressor for an ejector-type refrigerant cycle device includes a high pressure detector disposed to detect a physical amount having a relation with a high-pressure side refrigerant pressure of a refrigerant cycle, an evaporation pressure detector disposed to detect a physical amount having a relation with a refrigerant evaporation pressure in a suction side evaporator, a pressurizing estimating portion for estimating a pressurizing amount in a pressure increasing portion of an ejector to be increased in accordance with an increase of a pressure difference between the high-pressure side refrigerant pressure and the refrigerant evaporation pressure, and a suction pressure estimating portion for estimating a suction refrigerant pressure of the compressor by using the pressurizing amount estimated by the pressurizing estimating portion. Thus, a drive torque of the compressor can be accurately estimated in the ejector-type refrigerant cycle device.

TECHNICAL FIELD The present invention relates to an ejector refrigeration cycle including an ejector.

Ejector and manufacturing method thereof

A housing is configured into a tubular form and receives at least a portion of an ejector functional unit, which includes a nozzle and a body. A housing side opening radially penetrates through an outer peripheral wall surface and an inner peripheral wall surface of the housing and communicates with the fluid suction opening of the body. The housing side opening is adapted to join with a suction opening side external device, through which the fluid is drawn into the fluid suction opening.

Liquid pressure cycle having an ejector

The liquid pressure cycle having an ejector pressurizes the liquid refrigerant of the system with a positive displacement rotary pump rather than pressurizing the vapor refrigerant with a vapor compressor. This high-pressure liquid proceeds into two pressure streams. The first stream is directed to an expansion valve then on to an evaporator for space air or other medium cooling. The second stream is directed to the driving force input port of an ejector. This high-pressure input mixes with the low-pressure output from the evaporator. The result of this mixing provides for sufficient pressure enhancement to condense the combination refrigerant vapor as it passes through the condenser. The liquid flow from the condenser proceeds back to the liquid pressure pump and the cycle is repeated.
