Description
Technical Field
The utility model belongs to the petroleum machinery field, in particular to novel fracturing injection device.
Background
At present, in the actual production process of an oil field, an upper channel fracturing injection device, a lower channel fracturing injection device, a left channel fracturing injection device and a right channel fracturing injection device are adopted in the process of acidizing or fracturing operation of a well head, and due to the fact that the number of channels is small, the drift diameter is small, and working pressure is low, the injection flow quantity of acidizing fluid or fracturing sand is small, so that the working time is prolonged, and the working efficiency is reduced; when the oil pipe is fractured through the upper channel and the lower channel, acidizing fluid or fracturing sand is injected from the side channels, and the oil pipe is directly washed for a long time, so that the outer wall of the oil pipe is thinned, the fracture condition occurs, the oil pipe falls off a wellhead, and major safety accidents are caused; the above are problems that the production and use units need to solve together.
Disclosure of Invention
The utility model discloses a solve current fracturing injection device's passageway few, latus rectum is little, operating pressure is low, has technical problem such as the cracked potential safety hazard of oil pipe, provides a novel fracturing injection device.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a novel fracture injection device comprising: the oil pipe, the fracturing head, the continuous oil pipe protective sleeve, the metal sealing gasket ring, the union flange, the bolt, the conversion flange, the jackscrew and the rotary hoisting ring; the method is characterized in that: the design is that the fracturing head is a six-channel structure, the aperture of an upper vertical channel and a lower vertical channel is more than or equal to 180mm, the aperture of a side surface four-channel is more than or equal to 78mm, the working pressure is more than or equal to 70MPa, the side surface channel and a vertical channel are processed into an angle of 45 degrees, the side surface channel of the fracturing head is connected with a union flange through a bolt, a metal sealing gasket ring is placed in a sealing groove of the union flange, a jackscrew is screwed in a flange on the upper portion of the fracturing head under the action of external force, the jackscrew is tightened, a sharp corner of the jackscrew is tightly propped on a chamfer of a continuous oil pipe, so that the continuous oil pipe is fixed in the fracturing head, the oil pipe passes through the inside of an oil pipe protective sleeve, a rotary lifting ring is screwed on the periphery of the flange on the upper portion of the fracturing head for hoisting a fracturing injection device, the upper portion of the fracturing head is connected with the lower portion of a conversion flange, and the upper portion of the conversion flange is used for being connected with other wellhead equipment.
The utility model has the advantages that: the fracturing head is designed to be six channels, the aperture of an upper vertical channel and a lower vertical channel is more than or equal to 180mm, the aperture of a side surface four channel is more than or equal to 78mm, the working pressure is more than or equal to 70MPa, and the side surface channel and a vertical channel are processed to form an angle of 45 degrees, so that the requirements of more channels, large drift diameter and high working pressure of the fracturing injection device are met, the flow of acidizing fluid or fracturing sand is increased, the working time is reduced and the working efficiency is increased in the process of acidizing or fracturing operation at a well head; under the effect of external force, tighten up the jackscrew, make coiled tubing fix in the fracturing head, oil pipe passes through from the inside of oil pipe protective sheath, when acidizing fluid or fracturing sand from the side passageway is injected, directly erodees coiled tubing protective sheath, and protection oil pipe is not erodeed by acidizing fluid or fracturing sand, avoids oil pipe fracture, does not have the cracked potential safety hazard of oil pipe.
