Abstract

In a well-borehole (10) in production or testing Finding the information you need and Stored in the bottom unit (16), located below the cable of the dug pipe (12), under the test valve (20), this is done directly in the form of a sound signal between the bottom unit (16) and the device between the surface (24) For this purpose, an audio connection will be made between the instrument (24) and the pipe line (12), and the transducer is available in the apparatus and in the pit (16), the command is sent. In the opposite direction and in the form of an audio signal as well In particular, in the beginning of the search, the transmission of data and commands between the instrument (24) and the surface unit (22) can be done by any well-known means, such as an electrical signal through it. Cables (26)

Claims (2)

1. Method of obtaining the required data and storing it in the well bottom unit (16), obstruction (20) in the lower part of the dug line (12) in the borehole (10), where indicated by the manner in which the method The composition consists of the following steps. The provision of inter-surface instruments (24) in the dug line (12) over obstructions (20) in such a way that the apparatus's acoustic splice to the dredge hoses and transmissions are stored in the well bottom unit. (16) directly from the unit To inter-surface apparatus (24) in the form of an audio signal traveling in the drilling line (12) 2. The method specified in claim 1, directed by the manner in which the The position of the tool between the surfaces (24) is followed by a command sent to the bottom of the well. Which is transmitted directly from the instrument to the unit in the form of an audio signal Where the command consists of The commencement instruction which shall initiate transmission of the data 3. the method specified in Clause 1 or 2, directed by the manner in which The transmission of data to the machine between the skin (24) in the form of an audio signal is followed by the following steps. The conversion of audio signals to non-acoustic signals in the inter-surface instrument (24) and transmission from the inter-surface instrument (24) to the surface unit (22) in the form of non-audio signals. Specified in Clause 3, where directed by the manner The inter-surface apparatus (24) is used to connect to the surface unit (22) by a cable (26) where information is transmitted in the form of an electrical signal. 5. Method as stated in the claim. Clause 3, where directed by the manner in which the information Is transmitted between the instrument, between the surface (24) and the surface unit (22) in the form of a signal Electromagnet 6. Method as specified in any of Clause 1 to 3 of Clause 1. By the way the information is recorded in the instrument between the surface (24) and the instrument itself is brought up. At the surface to utilize the information 7. The device is used to find the required data and store it in the bottom of the well (16) Obstacles (20) in the lower part of the pipe line (12) in the borehole (10) where Directed by the manner in which the device consists of The inter-surface apparatus (24) is positioned in the dug line (12) over obstructions (20) and consists of an audio interlock (28) to connect. Tools with dredge pipes and paths (30, 32) to transmit data stored in the bottom unit (16) directly from the unit to the instrument between the surface (24) in the form of an audio signal. In claim 7, where directed by the manner Of the transmission (30, 32), it also allows commands for the well-bottomed units (16) to be sent directly from The inter-surface apparatus (24) goes to the unit in the form of an audio signal. 9. Equipment as described in Clause 7 or 8, where directed by the nature Where inter-surface instruments (24) consist of a path (32) for converting sound to Non-audio signal and is further composed by a method (26) for transmitting data between The instrument between the surface (24) and the surface unit (22) in the form of a non-acoustic signal 1 0. Equipment as specified in Clause 9, which is directed by the manner in which the signal The non-audio signal is sent along a cable (26) connecting the surface unit (22) to the instrument between the surface 1. 1. Equipment as stated in Clause 9, which is directed by the manner in which the signal The non-audio signal is an electromagnetic signal that is sent along the line of the excavator (12) 1. 2. Equipment as set out in Clause 8, where directed by the manner in which the inter-surface apparatus (24) constitutes a means for recording information. Which will be used after That brought up the tools TM1361 [14]
