The connection row pipe clamp includes bolt and two symmetrical clamping plates, and the greasing part is bolted on connection row pipe clamp
Middle part, the reinforced pipe is bolted on the both ends of connection row pipe clamp respectively.
The annular convex platform with connection row pipe clamp cooperation is fixedly installed on the reinforced pipe.
The positioning section of recess is provided on the annular convex platform, the connection row pipe clamp is clamped on positioning section.
More set connection row pipe clamps are separately fixed at the both ends and middle part of greasing part.
Using utility model has the advantages that
1, greasing part is fixed between two reinforced pipes more by the utility model by covering connection row pipe clamp, can make existing greasing part
Point stress when in use is changed to face stress, and so that greasing head is born pulling force and reach 1000kg or more, greatly improved
The tensile strength of greasing part can allow steel wire to enter in blowout prevention box between two parties relatively, reduce the abrasion to sealing element, improve blowout prevention
Box is to the sealing performance of borehole pressure fluid, well control risk caused by reducing because of seal fails, ensured operating equipment and
The safety of personnel.
2, greasing part is fixed between two reinforced pipes by the utility model, and is also secured at greasing part in connection row pipe clamp
Between, which further improves the tensile strength of greasing part.
3, the utility model passes through the annular convex platform being arranged on reinforced pipe, can connect between connection row pipe clamp and reinforced pipe
Stability.
4, the utility model passes through the positioning section being arranged on annular convex platform, can prevent entire grease pouring device due to stress
Deformation, improves the stability that grease pouring device uses.
5, more set connection row pipe clamps are separately fixed at the both ends and middle part of greasing part by the utility model, are conducive to further mention
Rise the tensile strength of greasing part.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of connection row pipe clamp in the utility model.
Label in figure are as follows: 1, greasing part, 2, reinforced pipe, 3, connection row pipe clamp, 4, annular convex platform, 11, flow tube, 12, greasing
Head.
Specific embodiment
The utility model discloses a kind of steel wire well testing grease pouring device, including greasing part 1, reinforced pipe 2 and cover townhouse more
Pipe clamp 3, the reinforced pipe 2 are symmetrically fixed on 1 two sides of greasing part by mostly set connection row pipe clamp 3, and reinforced pipe 2 and note after fixing
Rouge part 1 is parallel.
In the utility model, the connection row pipe clamp 3 includes bolt and two symmetrical clamping plates, and the greasing part 1 passes through spiral shell
Bolt is fixed on the middle part of connection row pipe clamp 3, and the reinforced pipe 2 is bolted on the both ends of connection row pipe clamp 3 respectively.Specifically,
Connection row pipe clamp 3 is fixed at 11 box cupling of flow tube of greasing part 1.
In the utility model, the annular convex platform 4 cooperated with connection row pipe clamp 3, the ring are fixedly installed on the reinforced pipe 2
The positioning section of recess is provided on shape boss 4, the connection row pipe clamp 3 is clamped on positioning section.
In the utility model, the quantity of the connection row pipe clamp 3 is preferably three sets, be separately fixed at greasing part 1 both ends and
Middle part.But three sets in actual use, can also be exceeded.
Greasing head 12 after installation and 2 section moment of inertia of reinforced pipe are analyzed below:
Design reinforced pipe 2 is hollow stem, 2 outer diameter D of reinforced pipe1It is 0.034 meter, 2 internal diameter d of reinforced pipe1It is 0.0125 meter, increases
The centre distance L of greasing head 12 of the strong pipe 2 to greasing part 13It is 0.115 meter, greasing head 12 and blowout prevention box length L2For 3.75m, note
The outer diameter D of rouge head 12 is 0.076m, and the internal diameter d of greasing head 12 is 0.063m.
According to moment of flexure stress formula, 2 cross section stresses σ of reinforced pipe is calculated.
Be 600kg in the pulling force of steel wire, then when to act on greasing head 12 power F be 12000N, 2 cross section of reinforced pipe by
Stress σ be 3.4 × 107N/m2:
If steel wire pulling force is 1000kg, then acting on greasing head 12 power F is 20000N, then 2 cross section of reinforced pipe by
Stress σ1It is 5.67 × 107N/m2:
It is Q235 that 2 material of reinforced pipe is selected in design, and yield strength is 23.5 × 107N/m2, it is transversal to calculate reinforced pipe 2
The stress σ and σ that face receives1, much smaller than selection steel yield strength, therefore the intensity of reinforced pipe 2 meets the requirement of implement countermeasure.
After reinforced pipe 2 is installed, according to Bending Moment Equations calculate 12 end of greasing head it is curved walk distance be w1:0.0214 meters
Contrast enhanced pipe 2 install before 12 end of greasing head it is curved walk distance w and installation after 12 end of greasing head it is curved walk distance w1,
After installation it is curved walk distance reduce 76.1mm, reduce curvature after 12 stress of greasing head, reduce steel wire to blowout prevention box seal
Part eccentric wear.
The operation in addition, steel wire of the applicant in July, 2017 to 8 mouthfuls of wells during December is given a trial lecture, has used existing note respectively
Rouge part 1 and grease pouring device described in the utility model, effect are as follows:
Existing greasing part 1: blowout prevention box sealing element individual well average wear rate is 80%, individual well sealing part abrasion quantity 4.0.
Grease pouring device described in the utility model: blowout prevention box sealing element individual well average wear rate is 22.5%, individual well sealing element mill
Damage quantity 1.125；Blowout prevention box sealing part abrasion rate reduces by 57.5%.
Conclusion: the utility model can greatly improve the tensile strength of greasing part 1, and the abrasion of sealing element is greatly reduced
Rate.
