摘要： Purging of fiber optic conduits in subterranean wells. A downhole optical sensing system includes an optical line, at least two tubular conduits, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits, and a purging medium flowed in one direction through one conduit, and flowed in an opposite direction between the conduits. A method of purging a downhole optical sensing system includes the steps of: installing at least two conduits and an optical line in a well as part of the sensing system, one conduit being positioned within the other conduit, and the optical line being positioned within at least one of the conduits; and flowing a purging medium through the conduits in the well, so that the purging medium flows in one direction through one conduit and in an opposite direction between the conduits.

摘要： A pulse width modulated downhole flow control. A downhole flow control system includes a flow control device with a flow restrictor which variably restricts flow through the flow control device. An actuator varies a vibratory motion of the restrictor to thereby variably control an average flow rate of fluid through the flow control device. A method of controlling flow in a well includes the steps of: installing a flow control device in the well, the flow control device including a flow restrictor which variably restricts flow through the flow control device; and displacing the restrictor to thereby pulse a flow rate of fluid through the flow control device.

摘要： A system and method are disclosed that provide for transmitting data from a downhole location to the surface. In one embodiment, a communications medium provides data transfer capabilities to the surface. A first downhole instrument is associated with the communications medium in order to measure a first downhole parameter and transmit first data relative to the first downhole parameter to the surface via the communications medium at a first time. A second downhole instrument is associated with the communications medium in order to measure a second downhole parameter and transmit second data relative to the second downhole parameter to the surface via the communications medium at a second time such that the first data is interleaved with the second data.
