Description
Technical field
The utility model relates to oil drilling field operation device technique field, in particular to the self-priming drilling fluid weight increasing device of one.
Background technology
In the wellbore construction operation of oil, geological drilling, boring when meeting high pressure zone needs raising drilling fluid density control high pressure zone fluid (gas) to enter in pit shaft, thus avoid the generation of blowout or well kick catastrophic failure, this process is called drilling fluid and increases the weight of.No matter domestic and international at present, drillng operation improves drilling fluid density two kinds of methods: one is easy weight increasing device, need many people coordinating operation, labour intensity is large, dust is vaporized more, causes environment pollution, harm worker health, or use crane to coordinate workman's construction operation, which increase security risk and cost payout; Another kind increases main equipment to realize automatic weight increasing, makes its construction cost higher.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of by negative pressure generator design principle, makes the heavy weight additives such as blanc fixe evenly be mixed into the self-priming drilling fluid weight increasing device of drilling fluid.
For this reason, the technical solution of the utility model is as follows:
A kind of self-priming drilling fluid weight increasing device, comprise heavy weight additive charging hopper, communication apparatus and negative pressure generator, the upper port of described communication apparatus is communicated with described heavy weight additive charging hopper, between described heavy weight additive charging hopper and described communication apparatus, be provided with butterfly valve.
Described negative pressure generator is an inversion T-shaped pipeline, the vertical tube of described inversion T-shaped pipeline is communicated with the lower port of communication apparatus by flange, infundibulate flow restriction is formed at the vertical tube inboard wall of tube body local protuberance of described inversion T-shaped pipeline, the lower port internal diameter of described infundibulate flow restriction is less than the transverse tube internal diameter of tube body of described inversion T-shaped pipeline to form negative pressure, and the butterfly valve be simultaneously arranged between heavy weight additive charging hopper and communication apparatus also may be used for the internal diameter of connecting pipe between control with negative pressure generator with the size of negative pressure in adjustable pipe.
Preferably, described communication apparatus is a threeway communication apparatus, described heavy weight additive charging hopper is connected with described threeway communication apparatus port the first connected entrance upwards by butterfly valve, described negative pressure generator second connected entrance downward with described threeway communication apparatus port is connected, and the third connecting mouth of described threeway communication apparatus is connected with heavy weight additive charge pipe by butterfly valve.
This self-priming drilling fluid weight increasing device both can adopt the packed heavy weight additive of large-tonnage to increase the weight of, also the packed heavy weight additive of little weight can be adopted to increase the weight of, by be separately positioned between heavy weight additive charging hopper and the second connected entrance and between third connecting mouth and heavy weight additive charge pipe, the drilling fluid realizing two kinds of approach of alternately closing and open of two butterfly valves increases the weight of process; Drilling fluid is through suction line flow at high speed and by described negative pressure generator, make to form continuous negative pressure in the tube chamber of described threeway, under the effect of pressure reduction, heavy weight additive is sucked weight increasing device by described suction line or heavy weight additive charging hopper by heavy weight additive, is evenly mixed into drilling fluid.
Compared with prior art, this self-priming drilling fluid weight increasing device is owing to adopting from draught negative pressure type structure, and structure is simple, easy to operate, applicability is strong, when weighted drilling fluid, Solid weighting agents evenly can be mixed into drilling fluid, improve and increase the weight of efficiency, to save time and laborsaving, and environment protecting is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the self-priming drilling fluid weight increasing device of the utility model;
Fig. 2 is the sectional view that the self-priming drilling fluid weight increasing device of the utility model is inverted the infundibulate flow restriction of T-shaped pipeline.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Fig. 1 ~ 2, this self-priming drilling fluid weight increasing device comprises heavy weight additive charging hopper 1, communication apparatus 3 and negative pressure generator 6, described communication apparatus 3 is a threeway communication apparatus, the upper port of described communication apparatus 3, namely the first connected entrance is communicated with described heavy weight additive charging hopper 1 and is provided with butterfly valve 2 between described heavy weight additive charging hopper 1 and described communication apparatus 3, described negative pressure generator 6 is an inversion T-shaped pipeline, the vertical tube of described inversion T-shaped pipeline is by the lower port of flange 5 with communication apparatus 3, namely the second connected entrance is communicated with, infundibulate flow restriction 9 is formed at the vertical tube inboard wall of tube body local protuberance of described inversion T-shaped pipeline, the lower port internal diameter of described infundibulate flow restriction 9 is less than the transverse tube internal diameter of tube body of described inversion T-shaped pipeline, one end of the transverse tube of described inversion T-shaped pipeline as drilling fluid inlet 7 other end as being connected for drilling fluid outlet 8 and with respective line, the third connecting mouth of described threeway communication apparatus is connected with heavy weight additive charge pipe 4 by butterfly valve 10.
The operating principle of this self-priming drilling fluid weight increasing device:
In operation process, the general heavy weight additive adopted is scheelite crystalline flour, when adopting large-tonnage packed scheelite crystalline flour weighted drilling fluid, close butterfly valve 2, insert in blanc fixe bag to be sucked by heavy weight additive charge pipe 4, open butterfly valve 10, now drilling fluid is through suction line 7 flow at high speed and by negative pressure generator 6, continuous negative pressure is formed in the tube chamber of threeway, under the effect of pressure reduction, blanc fixe is sucked into weight increasing device by suction line, and be evenly mixed in drilling fluid, namely this complete drilling fluid and increase the weight of process, the drilling fluid finally increased the weight of flows out from drilling fluid outlet 8, when adopting the packed scheelite crystalline flour of little weight to increase the weight of, heavy weight additive can be poured in heavy weight additive charging hopper 1, close butterfly valve 10, open butterfly valve 2, blanc fixe has been sucked drilling fluid and has increased the weight of process by same principle under described negative pressure generator 6 suction function.
Adopt from the drilling fluid weight increasing device of draught negative pressure type structure, structure is simple, easy to operate, and applicability is strong, when weighted drilling fluid, Solid weighting agents evenly can be mixed into drilling fluid, improve and increase the weight of efficiency, saves time and laborsaving, and environment protecting is good.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is all included within scope of the present utility model.
