摘要:
A sensing and data recording downhole system and method for monitoring of firing of a perforating gun system in a well, including a perforating gun system having charges or bullets for performing well perforation; and at least one of one or more downhole recorders and one or more fluid detection sensors located above, along, below or in array on the perforating gun system or inside the perforating gun system on a conveyance and configured to at least one of record sound waves generated by explosions of the charges or bullets during the firing of the perforating gun system and detect a presence of fluid within a body of the perforating gun system before and after guns of the perforating gun system are fired.
摘要:
A wireless modem for communication in a network of wireless modems via a communication channel includes a transceiver assembly, transceiver electronics and a power supply. The transceiver electronics include transmitter electronics, receiver electronics and at least one processing unit. The transmitter electronics cause the transceiver assembly to send wireless signals into the communication channel. The receiver electronics decode signals received by the transceiver assembly. The at least one processing unit executes instructions to (1) enable the transmitter electronics to transmit an identification signal into the communication channel, (2) receive data from at least one other wireless modem via the receiver electronics indicative of a unique identifier identifying the other wireless modem, and data indicative of at least one local sensor measurement related to the depth of the other wireless modem below the surface of the Earth, and (3) determine the position and/or relative order of the other wireless modem using the data indicative of the local sensor measurement. The power supply supplies power to the transceiver assembly and the transceiver electronics.
摘要:
A method for capturing a sample from a wellbore, comprising the steps of introducing a first message and a second message into a tubing positioned within the wellbore. The first message is directed to a first modem connected to a first sampler device to cause the first sampler device to collect a first sample. The second message is directed to a second modem connected to a second sampler device to cause the second sampler device to collect a second sample.
摘要:
A method and system are disclosed herein relating to transmitting data within a borehole. The method and system include having a transmitter disposed at a first location within the borehole and configured to generate a first signal, and more than one receiver and/or repeater disposed at a second location within the borehole. The receivers and/or repeaters are configured to receive the first signal, and further are configured to communicate with each other.
