    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 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: An electro-acoustic system for downhole telemetry employs a series of communications nodes spaced along a string of casing within a wellbore. In one embodiment the nodes are placed within the cement sheath surrounding the joints of casing and allow wireless communication between transceivers residing within the communications nodes and a receiver at the surface. The transceivers provide node-to-node communication up a wellbore at high data transmission rates for data indicative of cement sheath integrity. A method of evaluating a cement sheath in a wellbore uses a plurality of data transmission nodes situated along the casing string which send signals to a receiver at the surface. The signals are then analyzed.

    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 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 nodes employ electro-acoustic transducers providing node-to-node communication up a wellbore at high data transmission rates. A method of transmitting data in a wellbore uses a plurality of data transmission nodes situated along a tubular body to deliver an alternating electrical and acoustic transmission of data along the wellbore.
