Title:
MULTI-WELL-BASED INTERWELL LOGGING COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/056029
Kind Code:
A1
Abstract:
A multi-well-based interwell logging communication system, comprising a central station and a plurality of satellite stations. The central station comprises: a mobile base station (1) and a central terminal (3); a ground transmitter (4) for establishing an information transmission link with each satellite station in a broadcast manner by means of the mobile base station (1) and the central terminal (3); and a downhole transmitter (6) for receiving a basic beacon signal transmitted from the ground, and on the basis of the basic beacon signal, completing the transmission for interwell logging under the control of the ground transmitter (4) and realizing the communication and control of the interior of a transmitting well in the interwell logging. Each satellite station comprises: a satellite station terminal (8) located on the ground; a ground receiver (5) for performing point-to-point communication with the ground transmitter (4) by means of the satellite station terminal (8), thereby controlling a downhole receiver (7); and the downhole receiver (7) for completing the reception and acquisition for interwell logging under the control of the ground receiver (5) and realizing the communication and control of the interior of a receiving well in the inter-well logging.
