    摘要: A system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a tubular body either above or below ground, such as in a wellbore. The nodes allow for wireless communication between one or more sensors residing at the level of a subsurface formation or along a pipeline, and a receiver at the surface. The communications nodes employ electro-acoustic transducers that provide for node-to-node communication along the tubular body at high data transmission rates. A method of transmitting data in a wellbore is also provided herein. The method uses a plurality of data transmission nodes situated along a tubular body to accomplish a wireless transmission of data along the wellbore using acoustic energy.

    摘要: A system for downhole telemetry is provided herein. The system employs a series of communications nodes spaced along a tubular body in a wellbore. Each communications node is associated with a sensor that senses data indicative of a formation condition or a wellbore parameter along a subsurface formation. The data is stored in memory until a logging tool is run into the wellbore. The data is transmitted from the respective communications nodes to a receiver in the logging tool. The data is then transferred to the surface. A method of transmitting data in a wellbore is also provided herein. The method uses a logging tool to harvest data in a wellbore from a plurality of sensor communications nodes.

    摘要: A system for downhole telemetry employs a series of communications nodes spaced along a tubular body such as a pipe in a wellbore. The nodes allow for hybrid wired-and-wireless communication between one or more sensors residing at the level of a subsurface formation, and a receiver at the surface. The communications nodes employ electro-acoustic transducers that provide for node-to-node communication partially up a wellbore, and then high speed data transmission using a wire for the remaining distance up to the surface. A method of transmitting data in a wellbore uses a plurality of data transmission nodes situated along a tubular body to deliver wireless signals partially up the wellbore, and then wired signals the remaining distance.
