摘要:
A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in bottom hole assembly while simultaneously being compatible with a pressure pulse tool downhole thereof. The backpressure valve includes pressure generating capacity below its internal valve assembly so as to avoid the tendency of the assembly to throttle open and closed. Furthermore, the pressure generation is achieved in a manner avoiding cavitation. As a result, once the backpressure valve is opened, the pressure pulse tool is able to reliably communicate with surface equipment at the oilfield.

摘要:
A coiled tubing tractor assembly including a hydraulically powered tractor coupled to a coiled tubing having a fiber optic therethrough to provide communicative means, for example, to a monitor coupled to the tractor. The fiber optic may also be employed to control movement of the coiled tubing tractor. Additionally, a diagnostic tool may be coupled to the tractor wherein the tractor provides a communicative link between the diagnostic tool and the monitoring device.
摘要:
A method of performing a wellbore operation at an oilfield comprises providing a bottom hole assembly comprising a backpressure valve on coiled tubing, deploying the bottom hole assembly into the wellbore with the coiled tubing, operating the backpressure valve to control a flow of fluid thereabove, and performing distributed temperature sensor measurements above the valve.
摘要:
A method and apparatus for testing a multi-zone reservoir while reservoir fluids are flowing from within the wellbore. The method and apparatus enables isolation and testing of individual zones without the need to pull production tubing. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It may not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要:
A backpressure valve. The backpressure valve may be configured to maintain a substantially controlled pressure in coiled tubing uphole thereof while simultaneously being compatible with a ballistically actuated tool downhole thereof. The valve may include a housing with an uphole chamber in alignment with the coiled tubing and downhole chamber in alignment with the ballistically actuated tool. A gate mechanism disposed between the uphole and downhole chambers may thus be employed to receive a ballistic actuator from the uphole chamber for dispensing into the downhole chamber without sacrifice to pressure control within the coiled tubing.
