Definitions

  • the invention relates to the area of geophysics and, in particular, to the methods of noncontact data exchange between self-contained logging tools and a surface reader, as well as to the problem of noncontact charging of accumulator batteries of self-contained logging tools.
  • measuring tools are usually tripped in a hole by using two methods, namely, by using a cable or a wireline.
  • the first method uses a load-bearing logging cable through which data are transmitted to the surface and the logging tools are powered.
  • the advantage of this method is that it allows continuous data transmission. Due to big diameter and heavy weight of the insulated and armoured cable, it is difficult to trip tools in high-pressure holes.
  • Such a cable is serviced by a self-propelled unit designed for cable (wireline) operations, which results in additional expenses.
  • the second method uses a plain wireline to trip tools in a hole. In this case, the tools shall have self-contained power supply and memory units for temporary storage of the logging data.
  • the wireline is usually 1 to 2 mm thick and weighs tens of kilograms. Unlike the cable, the wireline is easier to service and a conventional tugger hoist is used for tripping operations.
  • the main disadvantages of using a logging cable in the logging operations are that it is difficult to trip logging tools in high-pressure holes and that it is difficult to seal the hole because of big diameter of the cable.
  • Using a plain wireline eliminates both of these problems, but retains laborious tool- retrieving operations for subsequent reading and accumulator battery charging.
  • a dedicated sealing device called 'lubricator' to be installed above the production tree is used for operations in producing wells.
  • the lubricator design allows removal and suspension of logging tools without unsealing the hole. Prior to tripping the logging tools in the hole, a required pressure is built in the lubricator. By opening the valve, the logging tools can be tripped in the hole, using a hoist.
  • Self-contained logging tools are equipped with recorders which record data into the internal memory, and the data are then read on the surface by a surface reader (or a surface computer).
  • the lubricator shall be disassembled for maintenance, data reading and accumulator battery charging purposes. This operation is a rather laborious and is associated with the hazard of fluid or oil spillage. Moreover, each such operation takes a lot of working time and requires the availability of highly skilled personnel.
  • the disadvantage of this system is that in case of a strong attenuation of the high- frequency data signal in the antenna, it is necessary to use radio frequency followers to be installed along the whole length of the wireline.
  • the use of such followers allows the data signal power to be maintained at a required level.
  • the logging tool tripping operations are considerably complicated by the fact that the frequency followers are to be placed and serviced on a wireline.
  • Patent EP 0678880 uses a downhole pressure and temperature measuring tool made in such a way as to allow its repair and rehabilitation without the need to shut in the well.
  • This tool is tripped in the hole, using flexible pipes, and is installed coaxially on the induction system which is permanently mounted in a retrievable gaslift valve mandrel.
  • the flexible pipes are then tripped out of the hole while the tool remains in the mandrel.
  • the cable connected to the induction system is brought out to the surface through the annulus; the cable is used for powering the tool and for reading the realtime data.
  • this tool cannot be used in hard-to- reach areas which require self-contained operation.
  • the technical result of the invention claimed consists in the development of a self-contained device for making noncontact data exchange and a method for charging accumulator batteries of self-contained logging tools by means of induction communication.
  • the important advantage of the engineering solution proposed is that the tool operates on a self-contained basis and that required operations are performed on the surface with the lubricator closed.
  • Induction communication is established between an induction coil wound round a radiotransparent adapter under the lubricator, and an induction coil placed in a charging and telemetering module the body of which is made of radiotransparent material.
  • a core is used for more efficient transmission of energy between the coils.
  • Figure 1 shows the general logging tool tripping scheme based on the use of a plain wireline, and the position of the radiotransparent adapter on the wellhead equipment.
  • logging tools (1) equipped with off-line memory are suspended on a wireline (2) and are handled by a hoist.
  • the steel wireline passes through sealed stuffing boxes (not shown) in the upper part of the lubricator (4).
  • the logging tools with the data recorded are tripped to the surface by the hoist through the wellhead equipment (5).
  • An adapter (3) made of fiber-glass reinforced plastic is installed between the lubricator (4) and the wellhead equipment.
  • Figure 2 shows the longitudinal section of the radiotransparent adapter during the moment of maximum approach of the internal induction coil to the external induction coil, where 12 is the core, 13 is the external induction coil and 14 is the induction coil which together constitute an induction system (20), 17 is the charging and telemetering module, 19 is the external reader.
  • the charging and telemetering module (17) is installed in the upper part of the bundle of the logging tools and is used for data exchange between the logging tools and the external reader (19).
  • the current in the winding (13) increases due to amplification of induction communication between the windings.
  • Maximum current in the induction coil (13) indicates that the hoist should be stopped and that the data exchange and accumulator battery charging processes should be started.
  • the combination of the winding (14), the external winding (13) and the core (12) will be described hereinafter as the induction system (20).
  • a data reading instruction is sent by using induction communication to the telemetering module (17) and the telemetering module then starts data transmission from the logging tools through the induction coil (14) to the induction coil (13) and further to the external unit (19) and to the surface personal computer.
  • the radiotransparent adapter (3) and the body of the telemetering module (17) shall be made of a sufficiently strong material (designed for hydrostatic pressure inside the wellhead equipment) characterized by low absorption of radio-waves in a range of 50 to 100,000 Hz.

Such optimization will increase the power transmitted to the secondary winding and will consequently reduce the accumulator battery charging time.

Abstract

L'invention porte sur le domaine de la géophysique et, plus particulièrement, sur des procédés d'échange de données sans contact entre des appareils de diagraphie autonomes et un lecteur de surface, ainsi que sur le problème du chargement sans contact de batteries d'accumulateur d'appareils de diagraphie autonomes. Le dispositif peut fonctionner de manière autonome et les opérations requises peuvent être exécutées en surface avec le lubrificateur fermé parce qu'une communication par induction est établie entre la bobine d'induction enroulée autour de l'adaptateur radio-transparent placé sous le lubrificateur et la bobine d'induction placée dans le module de chargement et de télémesure dont le corps est en matériau radio-transparent. Un cœur est utilisé pour une transmission plus efficace de l'énergie entre les bobines. Les appareils de diagraphie équipés d'une mémoire hors ligne et suspendus à un câble sont descendus dans un trou au moyen d'un palan. Le câble en acier passe par des presse-garnitures scellés placés dans la partie supérieure du lubrificateur. Dès qu'une série de mesures est terminée, les appareils de diagraphie, avec les données enregistrées, sont ramenés à la surface par le palan par le biais des équipements de tête de puits. Un adaptateur en plastique renforcé à la fibre de verre est installé entre le lubrificateur et les équipements de tête de puits.
