Description
Technical field
This utility model relates to production scene, oil field pumping well testing technical field, particularly to a kind of annulus logging well head
The special test pipe nipple that test port is connected with test strobe.
Background technology
Annulus logging well head is a kind of pumping well head device that Oil Field is conventional, can carry out when oil well normally produces
Test jobs, it is achieved pumpingh well dynamic monitoring.Test nipple joint connecting test port and test strobe, be testing tool,
The passage that instrument removes.Test nipple joint upper and lower joint taper pipe thread position during construction operation by moment of torsion or
Moment deforms and even ruptures, and easily causes oil and gas leakage even blowout out of control accident.With regard to test nipple joint self
Speech, pipe nipple pipe external diameter φ 43mm, tube wall 4.5mm, thread root and tooth top 1.5mm, screw thread position thickness of pipe wall only 3mm,
It is difficult to bear bigger moment of torsion or moment of flexure, easily damages during test jobs, be production scene, oil field test jobs mistake
Major hidden danger in journey.
Therefore, a kind of simple in construction, use safety, the test strobe adapter preventing threaded portion from rupturing is suggested.
Summary of the invention
The purpose of this utility model is to provide a kind of special test pipe nipple supporting with annulus logging wellhead assembly.
This utility model includes: top connection (1) and lower contact (3), at top connection (1) and the end of lower contact (3)
Portion is designed with conical tube external screw thread, it is characterised in that: screw tip is sequentially provided with packing ring (4) and clamping nut (6).
Top connection (1) and lower contact (3) are cylinder, and center is provided with through hole, in top connection (1) and lower contact (3)
End be designed with conical tube external screw thread, top connection (1) connecting test gate, lower contact (3) and annulus logging well
Mouth test port connects, when top connection (1) and lower contact (3) connect respectively at test strobe and annulus logging well head
After Hao, screw clamping nut (6), by top connection (1) and lower contact (3) and test strobe and annulus logging well
Mouth test port compresses, and Accident prevention occurs.
As improvement, the outer surface of top connection (1) and lower contact (3) is provided with projection (7), described projection (7)
For nut shape, i.e. realize top connection (1) or the rotation of lower contact (3) by spanner engaging.
Time actually used: when being not provided with projection (7) on the outer surface of top connection (1) and lower contact (3), need
Pipe wrench to be used fixes top connection (1) or lower contact (3), moves clamping nut (6) using wrench, it is achieved seal,
But under having oil condition, can cause and skid, therefore, in top connection (1) and lower contact (3) at pipe wrench engaging
Outer surface be provided with projection (7), it is possible to use convenient being fixed of the instruments such as spanner.
As improvement, the connecting portion of top connection (1) and lower contact (3) is provided with seal groove, is provided with sealing in seal groove
Circle (5), and by being located at the articulation (2) of top connection (1) and lower contact (3) junction by top connection (1)
Connect with lower contact (3).
Sealing ring (5) is increased in the middle of top connection (1) and lower contact (3), can be logical after pressurized overload at screw thread
Cross sealing ring pressure release.
A kind of test strobe adapter that this utility model is proposed can improve test nipple joint bottom thread stress, carries
High bending resistance, anti-twisting property.Eliminate the hidden trouble of equipment in test work progress.Make full use of original device agent structure,
Reasonable in design, solve original device defect in structure design.Compared with prior art this utility model has elimination and sets
Standby damage accident, oil and gas leakage even blowout out of control accident and personal injury accident, it is achieved oilfield safety produces, ensure
Well information in time, accurately enroll, rate when improving oil well production, reduce the input of production maintenance cost, it is achieved energy-conservation
The features such as consumption reduction.
Compared with prior art, this utility model can not only improve test nipple joint bottom thread stress, improve bending resistance,
Anti-twisting property.Eliminate the hidden trouble of equipment in test work progress.Make full use of original device agent structure, reasonable in design,
Solve original device defect in structure design, also there is abatement apparatus damage accident, oil and gas leakage even blowout out of control
Accident and personal injury accident, it is achieved oilfield safety produces, ensure well information in time, accurately enroll, and improves oil well
Production time efficiency, reduces the input of production maintenance cost, it is achieved the feature such as energy-saving and cost-reducing.
Accompanying drawing explanation
Fig. 1 is this utility model structural profile schematic diagram.
In figure: 1 is top connection, 2 is articulation, and 3 is lower contact, and 4 is packing ring, and 5 is sealing ring, and 6 is to compress spiral shell
Cap, 7 is protruding.
Detailed description of the invention
Embodiment 1: with reference to Fig. 1, for structural representation of the present utility model, including: top connection 1 and lower contact 3,
It is designed with conical tube external screw thread in the end of top connection 1 and lower contact 3, it is characterised in that: screw tip is sequentially provided with
Packing ring 4 and clamping nut 6.
Top connection 1 and lower contact 3 are cylinder, and center is provided with through hole, in the end of top connection 1 and lower contact 3 all
Being provided with conical tube external screw thread, top connection 1 connecting test gate, lower contact 3 is connected with annulus logging well head test port,
When top connection 1 and lower contact 3 are after test strobe and annulus logging well head connect, screw clamping nut 6,
