Abstract
A method for detecting drilling tool used on well drilling includes connecting above ground unit with receiver and computer to circuit of underground unit with detector, sending weak current detection signal containing defect information of drilling tool in drilling procedure to said receiver above ground by detector underground through drill collar and drill stem as well as square drill stem in sequence, using said computer to analyze information received by receiver for realizing detection on drill tool in real time continuously and dynamically.
Description
Technical field:
The present invention relates to drilling tool detection method in a kind of probing production drilling that a kind of oil, geological drilling production drilling, workover treatment use.
Background technology:
At present in oil, geological drilling exploitation, in the oil drilling, complicated technology wells such as deep-well, orientation well, sidetracked hole, horizontal well, Multilateral Wells are more and more, because the singularity of construction, cause construction period longer, the drilling tool fracture accident that causes because of the fatigability destruction of drilling tool happens occasionally.Therefore the drilling tool fracture accident is the most difficult in drilling engineering, and all cause enormous economic loss every year, and a very important ring is exactly that drilling tool detects in the drilling engineering, to give the anti-various complex situations that cause because of drilling tool and the generation of accident.In present oil well repairing operation, the down-hole fish is carried out in the fishing operation process, to carry out to the down-hole fish that large-tonnage lifts or the reversing of high pulling torque by drilling tool, therefore the destruction to drilling tool is very big, tend to cause new drillling tool twisting off accident, and then increased new difficulty of construction and economic loss again.The drilling tool inspection method of current routine is single drilling tool to be detected one by one by instrument on ground, or in the process of making a trip, drilling tool is detected by laying instrument at well head, the subject matter that it exists is: do not have continuity, can not creep into, carry out under the well workover condition in real time drilling tool, dynamically, continuous detection, creep into, fatigability to drilling tool under the salvaging condition destroys maximum, accidents such as drilling tool fracture also are to take place with this understanding mostly, and therefore this ground detection method can not play basic preventive effect.
Summary of the invention:
The object of the invention is to provide drilling tool detection method in a kind of probing production drilling, this method solved exist in the existing detection method do not have a continuity, can not to drilling tool creep into, carry out under the well workover condition in real time, dynamically, continuous detection, because creep into, fatigability to drilling tool under the salvaging condition destroys maximum, accidents such as drilling tool fracture take place mostly in the case, so this detection method has the generation that the prevention drilling tool accident has fundamentally been played in real-time, dynamic, the continuous detection to drilling tool.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly drill that the drilling tool detection method is to finish by the drilling tool pick-up unit in the production drilling, this device is that computer system, water swivel, annular receive instrument, square kelly, rotating disk, rig floor, drilling rod, drill collar, downhole detection instrument and form by down-hole and two ones on ground; Above ground portion is that ground reception instrument comprises that the annular that is located at square kelly top receives instrument and computer system (the two does not rotate with square kelly), annular is accepted instrument and is fixed by bolts to the water swivel bottom, annular is accepted instrument and is connected with the computer system circuit, can receive the signal that underground detection system sends, understand the signal that is received by computer system; Square kelly and water swivel screwed connection are driven the square kelly parts work of down-hole part by the running of rotating disk, rig floor; Square kelly and drilling rod, drilling rod and drill collar, drill collar and downhole detection instrument, downhole detection instrument and drill bit are screwed connection, the downhole detection instrument is provided with the weak electricity measuring system, the weak electricity measuring signal that is sent by this system passes through drill collar successively, drilling rod, square kelly, the crackle that detected drilling tool occurs in drilling process in the way, sand hole, the drill pipe deformations defect information is transferred to annular and receives the instrument deciphering of machine system as calculated again, realization is real-time to drilling tool, continuously, the dynamic detection, and can accurately provide the drilling tool damaged location, transmission between down-hole part and the above ground portion is to be meson with the drilling tool, and it plays constructing operation and gives the police, prompting, the generation of preventing accident, take the effect of technical measures.
Beneficial effect of the present invention is, a kind ofly drill that the drilling tool detection method can realize drilling tool is detected in the production drilling under the condition of creeping into, making a trip, this method can be real-time, disposable, continuous, dynamically whole down-hole equipments are detected, and the drilling tool damaged location can accurately be provided.This method can play to give to construction warns, points out, gives the accident prevention generation, takes the effect of technical measures.
Description of drawings:
