Description
Technical field:
The present invention relates to connector for logging while drilling recovery technique field, oil field, repair resistivity measurement particularly to a kind of band wire
Instrument technique.
Background technology:
Drill rod telemetry system is to develop rapidly in nearest 20 years and a gradually ripe class petroleum works service instrument.Along with
LWD instrument is gone into the well the increasing of number of times, and instrument body abrasion is the most serious, owing to down-hole lithology is distinguished, to instrument abrasion condition
The most different, indivedual LWD instrument wear-resistant strip a bite down-holes the most substantially to polish, and serious has worn out resistivity originally
Body, resistivity, without having transmitting antenna and reception antenna on magnetic shell wall, housing is uniformly distributed antenna slot, is placed with ferrum oxygen in groove
Body, notch high-temp glue seals, and excessive wear can cause antenna exposed outside, ultimately results in LWD tool device and scraps.
Current domestic LWD uses unit mostly to use the form of set wear-resistant sleeve to carry out protective resistance rate instrument originally with boring instrument
Body, the most first processes wear-resistant sleeve, uses hot-mounting process to be enclosed within instrument body afterwards.This method have the disadvantage that one be outside
Footpath excessive (172mm instrument wear-resistant sleeve external diameter is typically at about 189mm), once there are complex situations in down-hole, asks to process down-hole
Topic brings difficulty；Two is owing to wear-resistant sleeve size is relatively big, instrument string has two or more wear-resistant sleeve, in certain journey during way-type drilling unit
Affect build angle rate on degree, bring difficulty to engineering construction；Three temperature when being hot charging are high, so resistivity measurement can not be directly sleeved on
Short circuit body part, protection instrument effect is bad；Four be use other techniques be welded on body relatively costly, easily make resistance
Rate shell built-in line path loss is bad, causes instrument to be scrapped.
Summary of the invention:
The technical problem to be solved in the present invention is to provide a kind of band wire and repairs resistivity measurement instrument technique, and this technique realizes
Directly resistivity measurement instrument wear-resistant strip is repaired under with antenna conditions, by moment height energy-gathering pulse laser,
Make to be attached to instrument or non magnetic drill collar surface without magnetic, high rigidity amorphous state hard alloy powder metallurgical, have that technique is simple, surface
The advantage that temperature weldering low, molten is effective, wearing layer hardness is high, it is ensured that housing inside conductor, connection are excellent, can extend
In the service life of resistivity, reduce production cost.Overcoming existing set wear-resistant sleeve repair mode causes instrument body external diameter excessive,
Protection instrument effect is bad, easily makes the deficiency that resistivity shell built-in line path loss is bad.
The technical solution used in the present invention is: a kind of band wire repairs resistivity measurement instrument technique, and this processing step is such as
Under: use cemented carbide powder and high carbon dust to be hybridly prepared into non-magnetic alloy powder, utilize nitrogen automatic powder feeding device to carry out
Powder feeding, uses pulse type laser cladding equipment that the body housing without magnetic of resistivity measurement instrument is carried out multilamellar cladding, ground floor
Employing hardness is the non-magnetic alloy powder of 15～20 and carries out cladding by low pulse laser, and then using hardness is 20～70
Non-magnetic alloy powder carries out cladding layer by layer and covers, and last layer of employing hardness is the non-magnetic alloy powder of 70 and is swashed by high impulse
Light carries out cladding, and in whole welding process, temperature not can exceed that 100 degree.
The invention has the beneficial effects as follows: resistivity measurement instrument wear-resistant strip is directly entered under with antenna conditions by the present invention
Row is repaired, by moment height energy-gathering pulse laser, make without magnetic, high rigidity amorphous state hard alloy powder metallurgical be attached to instrument or
Non magnetic drill collar surface, has the advantage that technique is simple, surface temperature is low, molten weldering is effective, and wearing layer hardness is high, it is ensured that housing
Inside conductor, connection are excellent, can extend the service life of resistivity, reduce production cost.
Detailed description of the invention:
A kind of band wire repairs resistivity measurement instrument technique, and this processing step is as follows: use cemented carbide powder and high-carbon
Powder is hybridly prepared into non-magnetic alloy powder, utilizes nitrogen automatic powder feeding device to carry out powder feeding, uses pulse type laser cladding to set
The standby body housing without magnetic to resistivity measurement instrument carries out multilamellar cladding, the non-magnetic alloy that ground floor uses hardness to be 15～20
Powder also carries out cladding by low pulse laser, and the non-magnetic alloy powder then using hardness to be 20～70 carries out cladding layer by layer and covers
Lid, last layer uses hardness to be the non-magnetic alloy powder of 70 and carry out cladding, in whole welding process by high impulse laser
Temperature not can exceed that 100 degree.
It is understood that above with respect to the specific descriptions of the present invention, be merely to illustrate the present invention and be not limited to this
Technical scheme described by inventive embodiments, it will be understood by those within the art that, still can carry out the present invention
Amendment or equivalent, to reach identical technique effect；As long as meet use needs, all protection scope of the present invention it
In.
