Abstract
The utility model relates to the technical field of crushing ball seats, in particular to a double-hole crushing ball seat. The double-hole crushing ball seat comprises a ball seat, wherein an arc groove with a wide upper end and a narrow lower end is arranged on upper portion of the ball seat, a left side and a right side of a lower portion of the ball seat are respectively provided with a jet hole along an axial direction, and the jet holes are communicated with the arc groove. The double-hole crushing ball seat is reasonable and compact in structure and convenient to use, and due to the fact that the arc groove can be used to match with the jet holes, the double-hole crushing ball seat can achieve a large discharging volume of crushing construction, increase the number of crushing grades and the number of crushing construction layers or sections, improve crushing effect, and reduce the number of potential safety hazards.
Description
Technical field
the utility model relates to pressure break ball seat technical field, is a kind of diplopore pressure break ball seat.
Background technology
traditional pitching fracturing tool every layer (section) is thrown a ball; Open one deck (or a section) and carry out pressure break; Because oil pipe, the internal diameter of fracturing string and the diameter of ball all have strict restriction, so when carrying out pressure break, also very big to the restriction of pressing crack construction discharge capacity and pressure break progression; Seriously influence fracturing effect, do not obtained the maximization of fracturing yield increasing benefit.Traditional pressure break ball seat is a single hole; Ball of each throwing sets; Adopt the single hole ball seat owing to receive internal diameter and bulb diameter restriction, so that the ball seat area of passage is restricted is bigger, therefore when pressing crack construction raising discharge capacity; Corresponding operation pressure is also bigger, brings huge risk and serious restriction to pressing crack construction.Simultaneously, when adopting the single hole ball seat, because the extreme difference of ball seat diameter, the layer of pressing crack construction (section) number is restricted bigger.
Summary of the invention
the utility model provides a kind of diplopore pressure break ball seat; Overcome the deficiency of above-mentioned prior art; It can effectively solve existing pressure break ball seat and limited by the internal diameter of oil pipe, fracturing string and bulb diameter, has restricted pressing crack construction discharge capacity, pressure break sum of series pressing crack construction layer (section) number and influences fracturing effect and have the problem of potential safety hazard.
The technical scheme of
the utility model realizes through following measure: a kind of diplopore pressure break ball seat comprises ball seat; On the top of ball seat deep-slotted chip breaker wide at the top and narrow at the bottom is arranged, the jet orifice that communicates with deep-slotted chip breaker is arranged vertically respectively on the lower left side and the right side of ball seat.
Be to the further optimization of above-mentioned utility model technical scheme below or/and improve:
There is at least one annular slot in
above-mentioned outside, middle part at ball seat.
The top of
above-mentioned jet orifice is high outside and low outside cambered surface.
the utility model reasonable and compact in structure; Easy to use, through being used of deep-slotted chip breaker and jet orifice, realized pressing crack construction big discharge capacity, increased pressure break sum of series pressing crack construction layer (section) number; Improve fracturing effect, reduced potential safety hazard.
Description of drawings
accompanying drawing 1 is looked the sectional structure sketch map for the master of the utility model most preferred embodiment.
accompanying drawing 2 is the plan structure sketch map of accompanying drawing 1.
Coding in
accompanying drawing is respectively: 1 is ball seat, and 2 is deep-slotted chip breaker, and 3 is jet orifice, and 4 is draw-in groove.
The specific embodiment
the utility model does not receive the restriction of following embodiment, can confirm concrete embodiment according to the technical scheme and the actual conditions of the utility model.
are in the utility model; For the ease of describing; The description of the relative position relation of each parts all is to describe according to the Butut mode of Figure of description, as: the position relation of forward and backward, upper and lower, left and right etc. is what to confirm according to the Butut direction of Figure of description.
Below in conjunction with embodiment and accompanying drawing the utility model is further described:
like accompanying drawing 1, shown in 2, this diplopore pressure break ball seat comprises ball seat 1; On the top of ball seat 1 deep-slotted chip breaker wide at the top and narrow at the bottom 2 is arranged, two jet orifices 3 that communicate with deep-slotted chip breaker 2 are arranged vertically respectively on the lower left side and the right side of ball seat 1.During use, throw three balls at every turn and set, because the lower left side of ball seat 1 and the jet orifice 3 on right side have increased area of passage; When adopting big discharge capacity to construct, the operation pressure rising range can obviously slow down, and has reduced the risk of pressing crack construction; Reduced potential safety hazard, simultaneously, the diameter of the utility model is corresponding to diminish; The corresponding increase of the layer of pressing crack construction (section) number has improved fracturing effect effectively.
Can according to actual needs above-mentioned diplopore pressure break ball seat be done further to optimize or/and improve:
for the ease of installing, have at least one annular slot 4 in the outside, middle part of ball seat 1 shown in accompanying drawing 1.
shown in accompanying drawing 1, as required, the top of jet orifice 3 is high outside and low outside cambered surface.
above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
Claims (3)
