Abstract
The utility model provides a pressure guide sand blower for fracturing operation in an oil field, which is designed for improving the abrasion-resistant property of the sand blower in the case of fracturing with a large quantity of sands. The sand blower comprises an upper joint (1), a filter screen (2), a seal ring (3), a throttle nozzle (4), an anti-rotation pin (5), a pressure guide main body (6), a bushing (7), a stopper plug (8), and a lower joint (9), wherein, the upper end of the pressure guide main body (6) is connected with the upper joint (1), and the lower end thereof is connected with the lower joint (9); the throttle nozzle (4) is sheathed at the upper end of the pressure guide main body (6); the stopper plug (8) is welded at the lower end of the pressure guide main body (6);the bushing (7) is arranged inside the pressure guide main body (6); and the filter screen (2) is sheathed at the upper end of the throttle nozzle (4). The sand blower is mainly used for fracturing operation in an oil field, increases the thickness of the abrasion-resistant layer of a sand blowing nozzle, and improves the abrasion-resistant property of the sand blower, so as to guarantee development effects.
Description
Technical field: the utility model belongs to a kind of pilot sandblaster that is used for the oil field compression fracture operation.
Background technology: pressure break has great importance to the volume increase transformation of low-permeability oil deposit, but because the souring of load fluid, and the used sandblaster of conventional pressure break is at 45m
3It is comparatively serious to add under the situation of sand amount wearing and tearing, adds the sand scale and is restricted, influence volume increase correctional effect.Therefore, developed the abrasionproof pilot sandblaster that is used for the large sand amount pressure break.
Summary of the invention: the purpose of this utility model can improve the abrasionproof pilot sandblaster of its abrasionproof performance when being a kind of large sand amount pressure break of development.
The utility model mainly is made up of top connection, filter screen, sealing ring, throttle nozzle, anti-rotation pin, pilot main body, lining, plug and lower contact; Wherein pilot main body upper end is connected with top connection, and uses the anti-rotation dowel fixes, and the lower end is connected with lower contact, and use the anti-rotation dowel fixes, and throttle nozzle is sleeved on the upper end of pilot main body, and plug is welded on pilot main body lower end, lining is contained in the pilot main body, and filter screen set is contained in the upper end of throttle nozzle.
Lining is selected wear-resistant material for use; Have the pilot passage on the pilot main body; Have the sand jet outlet of symmetry on the pilot main body.
Compared with the prior art the utility model has following advantage:
Lining is selected wear-resistant material for use; Improved the abrasionproof performance of sandblaster.The pilot passage is placed on the outer of pilot main body and puts, and has increased the thickness of sand jet outlet wearing layer, and this design has improved the safety of machinery staged fracturing, provides guarantee for improving development effectiveness.
Description of drawings: Fig. 1 is the utility model structure diagram, and Fig. 2 is the A-A sectional drawing of pilot main body 6.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing: by shown in Figure 1, the utility model mainly is made up of top connection 1, filter screen 2, sealing ring 3, throttle nozzle 4, anti-rotation pin 5, pilot main body 6, lining 7, plug 8 and lower contact 9; Wherein pilot main body 6 upper ends are connected with top connection 1, and it is fixing with anti-rotation pin 5, the lower end is connected with lower contact 9, and it is fixing with anti-rotation pin 5, throttle nozzle 4 is sleeved on the upper end of pilot main body 6, plug 8 is welded on pilot main body 6 lower ends, and lining 7 is contained in the pilot main body 6, and filter screen 2 is sleeved on the upper end of throttle nozzle 4.
Lining 7 is selected wear-resistant material for use, has the pilot path 10 on the pilot main body 6; Have the sand jet outlet 11 of symmetry on the pilot main body 6.
During on-the-spot the use, this device is formed fracturing string with instruments such as packer and hydraulic anchors, the highly pressurised liquid of certain flow rate forms pressure drop through the throttle nozzle in the pilot sandblaster 4 during pressure break, inside and outside tubing string, cause chock pressure difference, upper packer is set, liquid also sets lower packet through the pilot path 10 simultaneously, isolates target zone, and liquid carries out pressure break through 11 pairs of these layers of sand jet outlet simultaneously.Pressure break is finished termination of pumping, the inside and outside no pressure reduction of tubing string, and the automatic deblocking of last lower packet can carry out another interval pressure break by the upper lifting pipe post.
The throttle nozzle 4 of this device can produce chock pressure difference and make that lower packet sets simultaneously on it, and sand jet outlet 11 also is the passage that fracturing fluid enters target zone simultaneously, also can be used as the anti-flushing well passage when the sand card.
