Abstract
The utility model disclosed is casing falling materials detecting device used in petroleum industry and connect using the utility model in existing regular wireline well logging apparatus to detect accurate depth of unknown falling materials in various down-hole casings. The apparatus includes magnetic localizer, weighted lever connected in sequence with detector. The utility model is provided with advantage of simple operation, high reliability, convenient maintenance, being capable of preventing blocking and twisting phenomenon of cable in construction process. Because of using magnetic localizer for detecting depth of casing falling materials, assuring celerity and accuracy of detecting data, substantially reducing workload of downhole operation, shortening operation time, expediting accident well repairing speed and providing safeguard for determination and implementing of production operation control measures.
Description
Technical field
The utility model belongs to the dynamic monitoring equipment of petroleum industry, particularly sleeve pipe junk sniffer.In existing conventional wireline logging equipment, connect and use the utility model, just can verify the accurate degree of depth of not clear junk in the various down-hole casings.
Background technology
In the exploration and development of petroleum industry, in producing well, often need carry out various down-holes construction operation, and the situation that downhole tool, tubing string, sucker rod fall appears in regular meeting in work progress, needs the corresponding construction of salvaging thus.In the past when salvaging construction operation owing to can not determine the accurate position of trouble of lost tool in hole, the position that lead stamp is played in common employing and operation is visited firmly, manual measurement tubing string length is determined junk, its construction technology wastes time and energy, the operating cost height, and big, thereby influence construction effect and progress with junk actual position data error.
Summary of the invention
The purpose of this utility model provides a kind of reliable operation, sleeve pipe junk sniffer easy to maintenance, can the accurate position of reflection trouble of lost tool in hole, quicklook ground, provide accurately in the well inner sleeve, implementing fishing, position data timely.
Adopt the technical program can reach above-mentioned purpose: sleeve pipe junk sniffer comprises magnetic locator, weighted lever and probe, and magnetic locator, weighted lever and probe are linked in sequence.
The utility model compared with prior art has following useful effect: simple to operate, and reliability height, easy to maintenance.Owing to adopt the mode of magnetic orientation, utilize magnetic locator and probe to survey, guaranteed the accurately quick of detection data.The utility model has adopted bulb, bulb insertion groove to connect, and it is free to guarantee that cable removes in the process rotation, can effectively prevent being hampered and beating and turn round of cable in the work progress.Because probe designs is the multi-hole overflow mode, guaranteed the speed of removing, the generation of the phenomenon that prevented to be hampered, shortened the activity duration, accelerated the accident well and repaired speed, further improved economic benefit, for the production and operation control measures determine and enforcement provides guarantee.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, sleeve pipe junk sniffer comprises magnetic locator, weighted lever 10 and probe 13, and magnetic locator, weighted lever 10 are linked in sequence with probe 13.Magnetic locator comprises the sliding pin 3 of magnetic orientation cylindrical shell 1, multicore, pressure ring 2 and 4 and the magnetic orientation assembly, the magnetic orientation assembly is installed in the magnetic orientation cylindrical shell 1, top fixed pressure ring 2, the sliding pin 3 of multicore and pressure ring 4, a tap of the signal lead 6 in the magnetic orientation assembly is connected with the prap of the sliding pin 3 of multicore.The magnetic orientation assembly comprises the signal lead 6 on permanent magnet 5 and 8, coil 7 and the coil 7, coil 7 two ends absorption permanent magnet 5 and 8, and the end flat at coil 7 is connected to the adsorption respectively, constitutes a permanent magnetic cylinder.Permanent magnet 5, coil 7 and permanent magnet 8 are for the axially extending bore structure, wrap up in insulating tape outward.A tap of the signal lead 6 on the coil 7 is connected with the prap of the sliding pin 3 of multicore, and another tap is welded on the housing of coil 7, constitutes signal circuit with magnetic orientation cylindrical shell 1.Magnetic orientation cylindrical shell 1 bottom is provided with anti-knocking over 9, the bottom external diameter is provided with screw thread.The upper chamber of weighted lever 10 has screw thread to be connected with the bottom external diameter of magnetic orientation cylindrical shell 1, and the shaft of weighted lever 10 is irritated plumbous casting to gain in weight, and base diameter is little to be the necking down structure, and its bottom is a bulb 11.The top profile of probe 13 is that pyramidal structure, low profile are arcuate structure, can reduce this device casing wall that scratches in the process of raising and decentralizing.The top body wall of probe 13 is provided with bulb insertion groove 12, the bottom body wall is provided with spout hole 14.Spout hole 14 is loose structure or four hole symmetrical structures, is the best with four hole symmetrical structures, is convenient to the well hydrorrhea and goes out, and reduces the resistance in the process of going into the well, and is illustrated as four hole symmetrical structures.The bulb insertion groove 12 of probe 13 is that a semienclosed slot conforms to the bottom shape of weighted lever 10, its bulb 11 is inserted with the bulb insertion groove 12 of probe 13 be connected.The aperture, top of probe 13 is less than the aperture in vertical hole, and the width of its vertical hole opening groove is less than its internal diameter.The bulb 11 of weighted lever 10 can either be inserted with bulb insertion groove 12 be connected, can from the vertical hole opening groove of bulb insertion groove 12, not deviate from again.
When specifically use at the scene, the magnetic orientation cylindrical shell 1 upper end box of this device is connected to the use of can going into the well on the borehole log bridle.Cable in the process of going into the well is because the bulb 11 of weighted lever 10 is connected with the bulb insertion groove 12 of probe 13, and weighted lever 10 can freely rotate mutually with probe 13, thereby the cable that is connected with borehole log bridle can not twined energetically.This device and head harness are connected the back go into the well by logging cable, the well logging beginning is hampered up to running into junk.In this process, the signal of telecommunication that coil 7 produces is transported to the ground digital control system by signal lead 6 by cable conductor and notes and form log, normal sleeve pipe nipple in the log and known normal sleeve pipe nipple standard value are carried out degree of depth check and correction, adjust degree of depth unanimity.Calculate the accurate degree of depth of junk according to the log data that is hampered then: the actual junk degree of depth=the record position that is hampered+this device distance of zero mark.This device distance of zero mark is exactly the length of magnetic locator middle part to probe 13 bottoms.
