    摘要: A communication system is disclosed enabling communication from a surface location to a downhole location where instructions communicated are executed. The system employs accelerometers to sense vibrations traveling within the annulus fluid or the tubing string. The accelerators provide signals representative of the vibration generated at the surface of the well to a microcontroller. The microcontroller is programmed to energize a nichrome element to actuate the downhole tool in response to a user-defined vibration sequence. The vibration sequence includes a defined number of vibration cycles. Each cycle includes alternating periods of vibration and no vibrations with each period lasting for a defined length of time. The user may program the parameters of the sequence and arm the vibration receiving unit on site through a handheld terminal that interfaces with the microcontroller.

    摘要: This invention provides oilfield spooled coiled tubing production and completion strings assembled at the surface to include sensors and one or more controlled devices which can be tested from a remote location. The devices may have upsets in the coiled tubing. The strings preferably include conductors and hydraulic lines in the coiled tubing. The conductors provide power and data communication between the sensors, devices and surface instrumentation. The coiled tubing strings are preferably tested at the assembly site and transported to the well site one reels. The coiled tubing strings are inserted and retrieved from the wellbores utilizing an adjustable opening injector head system. This invention also provides method of making electro-coiled-tubing wherein upper and lower adapters are connected to the coiled tubing and tested prior to transporting the string to the wellbore. The string preferably includes pressure barriers at both ends of the string. The string also includes a power line, hydraulic lines, data and communication lines and the desired sensors and devices for use with an electrical submersible pump.

    摘要: A system adapted for controlling and/or monitoring a plurality of production wells from a remote location is provided. This system is capable of controlling and/or monitoring: (1) a plurality of zones in a single production well; (2) a plurality of zones/wells in a single location (e.g., a single platform); or (3) a plurality of zones/wells located at a plurality of locations (e.g., multiple platforms). The multizone and/or multiwell control system of this invention is composed of multiple downhole electronically controlled electromechanical devices and multiple computer based surface systems operated from multiple locations. Important functions for these systems include the ability to predict the future flow profile of multiple wells and to monitor and control the fluid or gas flow from either the formation into the wellbore, or from the wellbore to the surface. The control system of this invention is also capable of receiving and transmitting data from multiple remote locations such as inside the borehole, to or from other platforms, or from a location away from any well site.
