Abstract
The utility model discloses a blending device of high pressure foam and mud has and connects room and the second of thoughtlessly joining in marriage as an organic whole and communicating first and thoughtlessly join in marriage the room, first room and the second of thoughtlessly joining in marriage thoughtlessly deviates from the end and is equipped with mud import and compound body export respectively in the room of joining in marriage, first cavity endotheca of thoughtlessly joining in marriage the room is equipped with the mud spray tube, and at the first foam pipe that is equipped with on thoughtlessly joining in marriage the oblique lateral wall in room, foam pipe and mud spray tube all with first room rigid coupling in an organic whole of thoughtlessly joining in marriage. The utility model discloses can make smooth interpolation in proportion of high -pressure foam and homogeneous mixing in drilling mud, effectively reduce the proportion of mud, reduce mud and to the pressure of well drilling working face, prevent accidents such as the well that collapses, ensure the success rate of well drilling.
Description
Technical field
The utility model belongs to drilling technology field, relates to a kind of blending device, is specifically related to the blending device of a kind of high-pressure foam and mud.
Background technology
At present, along with drilling depth increases, due to the pressure that the excessive generation of mud balance is very high, can cause the accidents such as well of collapsing, drilling depth is greatly limited.Adopt in mud, add the proportion that appropriate foam reduces mud, thus prevent drilling failure, because mud and foam all have certain pressure, and proportion is different, all can not be added in high-pressure slurry smoothly or add uneven.
Utility model content
The utility model solves above-mentioned the deficiencies in the prior art, the blending device of a kind of high-pressure foam and mud is provided, utilizes high-pressure injection to produce negative pressuren zone and siphon principle, high-pressure foam is added in drilling mud in proportion uniformly, effective reduction mud balance, guarantees the success rate of drilling well.
The technical scheme that the utility model adopts is: the blending device of a kind of high-pressure foam and mud, have and connect as one and the first compounding chamber communicated and the second compounding chamber, described first compounding chamber and the second compounding chamber deviate from end and are respectively equipped with mud inlet and mixture exports, mud jet pipe is set with in the cavity of described first compounding chamber, and foamed pipe is provided with on the first oblique sidewall of compounding chamber, described foamed pipe and mud jet pipe are all fixed in one with the first compounding chamber.
Further, described first compounding chamber and the second compounding chamber are split-type structural and are affixed stressed joint by uncovered uncovered plane to be integrated, and be provided with sealing ring at uncovered flat face place, described uncovered plane offers circular trough, by the uncovered sealing of described first compounding chamber and the second compounding chamber in the cavity that described sealing ring is placed in circular trough.
The beneficial effect that the utility model compared with prior art has: high-pressure foam can be made to add in proportion smoothly and be evenly mixed in drilling mud, the proportion of effective reduction mud, reduce mud to the pressure of drilling well working face, prevent the accidents such as well of collapsing, guarantee the success rate of drilling well, and practicality easy to process.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The blending device of a kind of high-pressure foam and mud, structure as shown in Figure 1, have and connect as one and the first compounding chamber 1 and the second compounding chamber 2 communicated, described first compounding chamber 1 and the second compounding chamber 2 deviate from end and are respectively equipped with mud inlet 6 and export 9 with mixture, mud jet pipe 8 is set with in the cavity of described first compounding chamber 1, and foamed pipe 7 is provided with in the first compounding chamber 1 tiltedly sidewall, described foamed pipe 7 is all fixed in one with mud jet pipe 8 with the first compounding chamber 1.
In the present embodiment, described first compounding chamber 1 and the second compounding chamber 2 are split-type structural and are affixed stressed joint by the uncovered plane 31 of uncovered 3 to be integrated, and be provided with sealing ring 4 in uncovered plane 31 joint, described uncovered plane 31 offers circular trough, seals uncovered 3 of described first compounding chamber 1 and the second compounding chamber 2 in the cavity that described sealing ring 4 is placed in circular trough.
During use, as shown in Figure 2 and Figure 3, the utility model is assemblied on base 10 by bracing frame 12, and by the import of mixture outlet 9, mud inlet 6 and foamed pipe 7 respectively with outlet gate valve 11, mud inlet lock 13 valve and foam inlet gate valve 14 connect.The drilling mud of certain pressure will be had as requested, the first compounding chamber 1 is sent into from mud inlet 6, and by mud jet pipe 8 ejection generation high velocity liquid stream at a high speed, negative pressure cavity is formed in the first compounding chamber 1, high-pressure foam is inhaled into the first compounding chamber 1 by foamed pipe 7, and in the second compounding chamber 2, be mixed to form the mixture slurry of new low ratio with mud slurry uniform, then send into drilling well working face through outlet 9.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting practical range of the present utility model, therefore all equivalent variations done with content described in the utility model claim, all should be included within the utility model right.
