Description
Technical field
This utility model relates to a kind of oil-well drilling equipment, particularly relates to a kind of down-hole pulse generation
Device pressure balance seal device.
Background technology
At present, oil-well drilling equipment pulse generator commonly used capsule-type pressure balance knot
Structure, realizes the pressure balance of pulser internal lubrication oil mud outside with pulser.Due to
Capsule structure is by temperature limiting, it is impossible to for high temperature well, and during down-hole uses often
There is capsules break oil leakage phenomenon, cause pulse generator normally to work, cause drilling well
Fault rate raises.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and is capable of pulse generation
The downhole pulser of device internal and external pressure balance pressure balance seal device.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of
Downhole pulser pressure balance seal device, including urceolus and described urceolus one end
Threaded high pressure pipe nipple, is provided with flat in the inner chamber that described urceolus and high pressure pipe nipple are formed
Weighing apparatus valve rod, described balance valve rod is positioned at described urceolus one end and is provided with balanced valve, balances valve rod position
It is provided with high pressure sealing joint in described high pressure pipe nipple one end.
It is positioned at the balance valve stem end outside described balanced valve and is provided with big jump ring.
It is provided with fairlead between described big jump ring and described balance valve rod.
It is provided with stop sleeve between described high pressure sealing joint and described high pressure pipe nipple, is positioned at institute
State and outside stop sleeve, be provided with little jump ring.
It is provided with sealing ring between described high pressure pipe nipple and described balance valve rod.
It is stifled that the outer wall of described high pressure pipe nipple is provided with oil.
The beneficial effects of the utility model are: this equipment safety is reliable, simple in construction, assemble
Convenient, pulse generator internal and external pressure balance can be realized, sealing function can be effectively played, can
Reduce logging while drilling apparatus fault rate.

Detailed description of the invention
With detailed description of the invention, this utility model is made the most below in conjunction with the accompanying drawings
Bright:
As it is shown in figure 1, a kind of downhole pulser pressure balance seal device, including
The high pressure pipe nipple 10 that urceolus 1 is connected with described urceolus 1 threaded one end, at described urceolus 1
Valve rod 5, described balance valve rod 5 is balanced with the inner chamber of high pressure pipe nipple 10 formation is provided with
Be provided with balanced valve 3 in described urceolus 1 one end, balance valve rod 5 is positioned at described high pressure pipe nipple 10
One end is provided with high pressure sealing joint 11.It is positioned at the balance valve rod 5 outside described balanced valve 3
End is provided with big jump ring 2.It is provided with guiding between described big jump ring 2 and described balance valve rod 5
Set 4.It is provided with stop sleeve between described high pressure sealing joint 11 and described high pressure pipe nipple 10
8, it is positioned at outside described stop sleeve 8 and is provided with little jump ring 7.Described high pressure pipe nipple 10 and institute
State and be provided with sealing ring 6 between balance valve rod 5.The outer wall of described high pressure pipe nipple 10 is provided with
Oil stifled 9.
Work process:
Urceolus 1 and balance valve rod 5 are threadedly secured on high pressure pipe nipple 10 respectively, high
Means of press seals joint 11 is fixed in high pressure pipe nipple 11 by little jump ring 7 and stop sleeve 8.
Balanced valve 3 and balance valve rod 5 matched in clearance, balance valve rod 5 end arranges big jump ring 2,
Prevent balanced valve 3 because accidentally slipping out balance valve rod 5.When lubricating oil enters arteries and veins by oil filler point
When rushing generator inside, lubricating oil is effectively blocked in pulse generation by high pressure sealing joint 11
Inside device, in high pressure pipe nipple 10, form height nip, serve sealing function.Pulse
Generator is when underground work, and balanced valve 3, by moving back and forth on balance valve rod 5, comes
Realize the pressure balance of mud and lubricating oil.
