Abstract
The utility model provides one can clean well drill pipe coupling, and it is primarily of slope, box cupling tube wall, internal thread, draw-in groove, " V " type runner composition.Slope is positioned at box cupling both sides, roughly becomes 30 ° with horizontal plane, can prevent box cupling section generation lock of tool drilling and reduce fluid energy losses.Coupling pipe wall thickness determines the tensile strength of box cupling, and internal thread is for connecting front and back drilling rod.When upper box cupling, draw-in groove plays the effect of fixing box cupling, and its sloped sides also can prevent lock of tool drilling from occurring." V " type runner can alter flow to, and impels fluid to form high-speed rotary turn of tidal stream.When fluid flows through box cupling, a part of fluid is along inclined plane and box cupling outside wall surface flow forward; After another part fluid flows through " V " type runner, flow to and change, form high-speed rotary turn of tidal stream, impact the cutting bed of box cupling front portion, play the effect of the anterior well of purification box cupling.The utility model structure is simple, easy to use, high to the anterior hole cleaning efficiency of box cupling, ensure that carrying out smoothly of wellbore construction process.
Description
Technical field
The utility model relates to oil and gas drilling well drilling bar box cupling technical field, relates more specifically to one and can clean well drill pipe coupling.
Background technology
In oil and gas drilling process, the connection between drilling rod is realized by box cupling, and the external diameter of most of box cupling is greater than the external diameter of drilling rod.The wall thickness of box cupling is too little, then tensile strength is inadequate; The wall thickness of box cupling is too large, then upset bore hole annulus Flow Field Distribution, make easily to form cutting bed in box cupling front portion, affect the clean-up effect of well.Therefore, if a kind of simple, practical, box cupling that can clean well can be invented, tensile strength problem and the landwaste cleaning problems of the existence of box cupling place will be solved, carrying out smoothly of guarantee wellbore construction simultaneously.
Summary of the invention
The purpose of this utility model is: provide one can clean well drill pipe coupling.
In order to achieve the above object, the technical solution adopted in the utility model is:
The utility model one can clean well drill pipe coupling, comprises slope, box cupling tube wall, internal thread, draw-in groove, " V " type runner.Slope is positioned at box cupling both sides, and gradient is about 30 °.The thickness size of box cupling tube wall, determines the intensity of its tension.Internal thread is for connecting front and back drilling rod.Draw-in groove is positioned in box cupling outside wall surface, and its left and right sides are slope, and draw-in groove is the effect playing fixed caliper at upper box cupling." V " type flow passage box cupling both sides flow region, alter can flow to, forms high-speed rotary turn of tidal stream, and runner wall adopts erosion resistance alloy to make.When fluid is from Annular cutting to box cupling, a part of fluid is along slope and box cupling outside wall surface flow forward; Part fluid, flows through " V " type runner, changes and flows to, and forms high-speed rotary turn of tidal stream, impacts the talus deposit region of box cupling front portion, so just reaches the object of the anterior well of clean box cupling.
Advantage of the present utility model: structure is simple, easy to use is high to the anterior well cleaning efficiency of box cupling.

Fig. 2 is the structural representation of A-A section in Fig. 1.
Fig. 3 is the structural representation of B-B section in Fig. 1.
Fig. 4 is a kind of streamline distribution figure cleaning well drill pipe coupling of the utility model.
In figure: 1. slope, 2. box cupling tube wall, 3. internal thread, 4. draw-in groove, 5. " V " type runner.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of structure chart cleaning well drill pipe coupling of the utility model, forms primarily of slope 1, box cupling tube wall 2, internal thread 3, draw-in groove 4, " V " type runner 5.Slope 1 is positioned at the box cupling left and right sides, roughly becomes 30 ° with horizontal plane, can prevent box cupling section bit freezing, also can reduce fluid impact box cupling back step and wear the energy loss come.The thickness of box cupling tube wall 2, determines the tensile strength of box cupling section.Internal thread 3 is for connecting front and back drilling rod.Draw-in groove 4 is positioned on box cupling outer tube wall, has certain degree of depth, in upper box cupling process, can be used for fixed caliper, and the slope of draw-in groove 4 both sides also can prevent this section from lock of tool drilling occurring." V " type runner 5 can the flow direction of alter, makes laminar flow become high-speed rotary turn of tidal stream, impacts landwaste accumulation area.
As shown in Figure 4, a kind of streamline distribution figure cleaning well drill pipe coupling of the utility model, the fluid of annular space high speed motion, after flowing to box cupling, a part of fluid is along inclined plane 1 and box cupling outside wall surface flow forward; Another part fluid enters " V " type runner 5, changes the flow direction, flows out from the box cupling other end, forms high-speed rotary turn of tidal stream, impacts the cutting bed of box cupling front portion, achieves cleaning the anterior borehole segments of box cupling.Simple, easy to use, the clean well efficiency of this apparatus structure is high, has to utilize to ensure safety drilling in drilling process.
