Description
Technical field
It is specifically a kind of the utility model is related to a kind of oil gas field oil, gas and water well underground well testing operation tool technique
Fish mouth type well testing gauguste cutter is a kind of tool entering pit shaft dredging before well for steel wire oil well test instruments, is suitable for including High angle
Various well testing operations including well, horizontal well, complex working condition well, belong to petroleum natural gas exploration field.
Background technology
With the quickening of oilfield prospecting developing speed and oil-gas exploration and the continuous refinement of oil gas field work, well testing workload
It is increasing.For wax deposition, icing, incrustation scale, hyrate, sand, viscous crude or mud etc. is tended to have in winter oil, gas well, well head is caused
Section and underground block, and oil well test instruments cannot smoothly be transferred to precalculated position, in order to ensure that pit shaft is unimpeded, make in oil, Gas well test
It is required to directly connect with steel wire using gauguste cutter before industry, drifting operation is carried out in tripping in oil/gas well, but situation is complicated in well, it is past
It is past that drifting job execution is made to be difficult to smoothly complete.This just proposes the requirement on higher function to gauguste cutter tool, presently used
Gauguste cutter there are the problem of mainly one section of upper end circular arc formation runner, lower end is a cylinder, has a single function, does not set
Crushing function is set, often at the predetermined well depth position of no arrival with regard to being hampered halfway, is hampered when having needed, not only personnel work
Intensity is big, and exacerbates the abrasion of steel wire and well testing equipment, and operating efficiency is low, and construction cost is high, long in time limit, influences oil/gas well
The raising of normal production and economic benefit.
It can be seen that the quality of gauguste cutter directly determines the success or failure of construction operation.With oilfield prospecting developing speed
Accelerate and the continuous refinement of oil-gas exploration and oil gas field work, well testing work are more and more frequent.Higher is proposed to well testing technology
Requirement, must assure that in underground drifting construction operation it is unblocked in well, just can guarantee well testing test construction it is normal into
Row.
Utility model content
The utility model is intended to existing for the above-mentioned prior art defect and deficiency, and it is logical to provide a kind of fish mouth type well testing
Well is advised, and the utility model has the advantages that reasonable in design, highly practical, safe and reliable.
The utility model is realized by using following technical proposals：
A kind of fish mouth type well testing gauguste cutter, it is characterised in that：Including connector and main body, the main body includes the connection on top
The broken resistance part in portion and lower part, the hollow formation discharge-channel of body interior, surface is provided with outside the main body is connected to the discharge-channel
Discharge orifice, the broken resistance part is in fish mouth shaped, is formed by blade and into channel in broken resistance part, into channel and discharge-channel company
Logical, the end in broken resistance part is arranged in blade.
The blade is "-" type blade, and the length direction of blade is consistent with the axial direction of main body, and blade is located at
Fish mouth shaped breaks the top of resistance part, is had in the both sides of blade described into channel.
The discharge-channel is circle.
The main body is connect by interconnecting piece with joint screw thread.
The discharge orifice is two, is in 180 ° of radial equipartitions in main body, and the axial line for discharging centerline hole and main body is in
60 ° of angles.
Compared with prior art, what the utility model was reached has the beneficial effect that：
One, the utility model using " the hollow formation discharge-channel of body interior, outside the main body surface be provided with and the discharge
The discharge orifice of channel connection, the broken resistance part are in fish mouth shaped, are formed by blade and into channel in broken resistance part, into channel with arrange
Put channel connection, the end in broken resistance part is arranged in blade " technical solution, can be reduced in drifting liquid or solid mince into
The resistance entered, it is easier to keep solid hyrate, ice broken, the solids or soft matter of the downward drifting wall attachment of guiding regulator, tool
Have the advantages that uniform force, penetration power are strong, drifting speed is fast, indeformable and durable.
Two, the structure communicated into channel with discharge orifice by interconnecting piece and discharge-channel of the utility model, then can
Reduce the liquid medium and solid disintegrating slag resistance in decentralization process, only need to play gauguste cutter next time can smoothly, efficiently complete
Borehole wall dirt drifting construction task, reduction repeat, lower number, avoid previous gauguste cutter and do not cross well head, need to adopt again
The tedious procedure of measure drifting again is taken, reduces and repeats to remove number.
Three, the utility model is using " blade is located at the top that fish mouth shaped breaks resistance part, and institute is had in the both sides of blade
State and enter channel " technical solution, obturator can be made to pass through two and be discharged by discharge-channel into channels；Meanwhile discharge-channel
It is rounded, and be one, channel volume is increased in the case where retainer body internal diameter is constant, to reduce resistance.
Four, two discharge orifices in main body are in 180 ° of radial equipartitions by the utility model, and in two major diameter discharge orifices
Heart line is in the structure of 60 ° of angles with the axial line of main body, can further decrease the liquid medium and solid during tripping in
Disintegrating slag resistance, reduces flow resistance to greatest extent, unblocked when to ensure tripping in oil well test instruments, and improves to greatest extent
Sticky well and solids block the possibility of well gauguste cutter tripping in.
Five, the utility model is simple in structure, easy to process, highly practical, can be saved the construction time using the gauguste cutter,
Construction speed is accelerated, construction efficiency is greatly improved, mitigates labor intensity, saves a large amount of operating costs, solving can not
Drifting is suitable for popularization and application to the problem of predetermined depth.
Six, the utility model is in oil, the construction of gas and water well operations, because it breaks resistance part to solid using the fish mouth shaped with blade
The pulverization of body hyrate, ice, regulator connectivity is good, can avoid, to the swabbing on stratum, effectivelying prevent attachment in well
Formation after, block oil well test instruments lower going-into-well under channel, and can not well testing test the phenomenon that, effectively avoid influence Party A production
It is normally carried out.The generation of instrument card resistance phenomenon is avoided, job execution progress is improved, shortens construction period, increases oil and gas production, tool
There is good economic benefit.
Seven, the utility model can play to soft matter drifting during drifting and release well head hyrate, knot
The purpose that ice blocks, moreover it is possible to prevent the fine tool of chance card risk occurred when drifting, avoid repeating rountrip, effectively improve
Job execution effect, not only alleviates labor intensity, shortens the construction period, and keeps well testing procedure connection even closer, reduces operating cost,
It is opposite to extend the oil/gas well production time, improve oil gas well production.
