    摘要: A system is used with a well that has a downhole tool which is responsive to a stimulus. The system includes a fluid circulation path that is connected to circulate a fluid and a flow restrictor that is connected in the fluid circulation path and located at the surface of the well. A controller causes the flow restrictor to selectively alter flow of the fluid in the circulation path, and a link is coupled to the circulation path to furnish the stimulus to the downhole tool in response to the alteration of flow by the flow restrictor.

    摘要: A multiple wellbore tool apparatus consisting of a plurality of microprocessor implemented wellbore tools is disposed in a fluid filled wellbore, and an input stimulus having a predetermined signature propagates down the wellbore fluid to all of the wellbore tools. The plurality of wellbore tools each include a microprocessor implemented controller board as well as an included wellbore tool and an acoustic receiver transmitter transducer connected to an output of the controller board. In addition, each of the microprocessors of each controller board include a memory which stores its own unique microcode programming. In response to the input stimulus, the controller board of a first wellbore tool determines that a correspondence exists between the signature of the stimulus and information stored therein and generates an output signal. The output signal may operate an included wellbore tool, or, in response to the output signal, the acoustic transmitter may transmit a first acoustic signal either through an outer housing of the multiple wellbore tool apparatus, or through the wellbore fluid, to all of the other wellbore tools. In response to the first acoustic signal, the controller board of a second wellbore tool will operate its included wellbore tool. When its operation is complete, that included wellbore tool will transmit a signature confirmation signal back to its controller board indicative of completion of its operation. That controller board will respond By instructing its acoustic transmitter to propagate a second acoustic signal through the outer housing or the wellbore fluid. A controller board of a third wellbore tool will respond to the second acoustic signal by operating its included wellbore tool. The above operational sequence is repeated until all of the included wellbore tools of the plurality of wellbore tools of the multiple wellbore tool apparatus are automatically operated in a pre-programmed manner as defined by the microcode programming encoded in the plurality of microprocessors.

    摘要: In a wireline data transmission system for passing data between downhole and surface locations in a wellbore, a system for transmitting data at a frequency above the relatively low roll of frequency of a wireline permits higher data rates to be transmitted over the wireline than would be possible using standard digital data formats. The present system utilizes short duration pulses which are placed on the wireline in conformity to the transition edge between voltage levels in a typical digital data format, and thus transmits the digital data over the wireline in a manner which is not adversely affected by the phase shifting which normally occurs when bi-level voltage data formats are used for data transmission over a wireline. The short duration pulses are placed on the wireline at a time position in a data format that corresponds to the beginning of a bit period and the pulse width is such that it only occupies a fraction of the bit period so that any phase shifting on the pulse does not shift the pulse into a succeeding bit period to thereby adversely affect data interpretation.

    摘要: A method for controlling drilling fluid rate in a wellbore is disclosed. A drill string is disposed into the well and connected to a formation testing or sampling tool. Drilling fluid is circulated at a first rate through the drill string. Data related to the wellbore, a formation about the wellbore or the formation sampling tool is transmitted to a processor. Upon analysis of the data, the drilling fluid circulation rate is changed to a second rate that is different from the first rate.
