INTER-TOOL COMMUNICATION FLOW CONTROL IN TOOLBUS SYSTEM OF CABLE TELEMETRY |
摘要 |
Systems and methods for inter-tool communication in toolbus systems in cable telemetry. The systems can include downhole equipment deployable into a wellbore via a cable, The downhole equipment can include a toolbus, a toolbus master node including a buffer, and nodes operatively coupled to the toolbus master node via the toolbus. Each of the nodes includes a buffer. Of the one or more nodes, a sending node sends a message, and a receiving node receives the message via the toolbus master node and sends a buffer full message to the toolbus master node when the buffer of the receiving node is full. The toolbus master node sends a buffer full message to the sending node and the receiving node when the buffer of the receiving node is full, and buffers the message at the toolbus master node until the receiving buffer is not full. |
