Abstract

A method for transferring data between an object (3) moving in an electrically conductive well tubular (2) and a remote station (7) either located at the surface or inside the well bore (1) comprises the step of: moving the object (3) through the well tubular (2); establishing electrical contact during the movement between the object and the well tubular via a sliding or other electrical contact (6, 13); and transmitting data from the object via the electrical contact and well tubular to the remote station during said movement. The invention also relates to a movable object for use in said method, which object comprises: data generating means; contact means (6, 13) for establishing contact between the data generating means and an electrically conductive well tubular (2); power storage means; and propelling means for moving the object through the well tubular.

Description

METHOD AND DEVICE FOR TRANSFERRING DATA BETWEEN AN OBJECT MOVING IN A WELL TUBULAR AND A REMOTE STATION
Background of the Invention
The invention relates to a method for transferring data between an object moving in an electrically conductive well tubular and a remote receiver/transmitter station in a well bore or at the surface.
During drilling and operating a petroleum or a gas well it is in some circumstances necessary to run objects up and down the well bore, which objects perform some kind of operation, such as data logging or inspection of the well bore casing. If the object is used as a casing inspection tool then it may be configured to detect casing joints where adjacent casing sections are screwed together. By counting the amount of casing joints passed during descent of the tool into the well an accurate method for monitoring the depth of the tool within a well is provided. The tool may inspect the integrity and thickness of the casing or other well tubular by an Electromagnetic Acoustic Transmission ("EMAT") inspection technique . Also downhole measurement equipment is known, which monitors for example the drilling operation or monitors certain parameters during production of the well.
When moving an object in a well, the data can be stored in the object, but this has the disadvantage that no real time data is available. It is known to exchange data between the object and the surface via electric cables. These cables have to be of sufficient strength in order to prevent cable breakage as a result of the length of the cables and/or as result of the rough environment in a well bore. Also extra equipment has to be provided to reel in the cable.
It is an object of the invention to provide a method in which the above-mentioned disadvantages are at least partly eliminated. Summary of the Invention
This object is achieved by a method according to the invention, which method comprises the steps of: - moving the object in the well tubular; establishing electrical contact during the movement between the object and the well tubular, such as a tubing or a casing via an electrical contact mounted on the object; and - establishing data communication between the object and a remote station, positioned either in the well or at surface, via the well tubular during said movement.
By establishing electrical contact via a sliding, rolling or other electrical contact between the object and a well tubular, the data can be exchanged via said tubular and eliminates the necessity of using cables in order to get real time data from the object.
In a preferred embodiment of the method according to the invention, the method comprises the step of sending data from a remote station located in the well or at surface via the well tubulars to the object. This provides for a two-way communication between the remote station and the object making it possible to control the object from the remote station. In another preferred embodiment of the method according the invention, the method comprises the step of sending power from the surface via the well tubulars to the object. Preferably the power is transmitted to and stored in the object, for example through trickle charging of a battery or capacitor. By supplying power to the object it is possible to operate the object for an extended period of time in the well bore. The invention also relates to an object for use in the method according the invention, which object comprises: data generating means; contact means for establishing contact between the data generating means and an electric conducting well tubular; and propelling means for moving the object in the well bore.
The contact means comprise preferably at least one wiper. A wiper has the advantage that it runs easily over irregularities of the casing wall.
In another embodiment of the invention the propelling means comprise a winch. This is a very reliable means for propelling the object, as the object can always be pulled out of the well bore, even when the electrical contact is interrupted for example due to a mal-function. Description of a preferred embodiment
These and other advantages of the invention are further described in conjunction with the accompanying drawing.
In the drawing figure 1 shows a schematic cross section of an embodiment according to the invention.
Figure 2 shows a schematic sectional view of a second embodiment according to the invention. In figure 1 a well bore 1 is shown, which is lined with a steel casing 2. This steel casing is electric conducting . In the well bore 1 an object 3 is ovably arranged. This object 3 has four cater-pilar tracks 4 for propelling the object 3 through the well bore 1.
In the object 3 data generating means 5 are arranged. This could be for example a data logging device. This data generating device 5 is connected to wipers 6 which are in contact with the casing 2.
Data generated in the device 5 can be sent through the wipers 6 via the casing 2 to a receiving station 7 at the surface level.
In figure 2 a second embodiment is shown. In the well 1 an object 10 is arranged, which is suspended from a cable 11 of a winch 12. The object 10 has wipers 13 which are in contact with the casing 2. Data generating means 14 can communicate via the wipers 13 and the casing 2 with a device 15 at the surface level.
