WELLBORE FRAC TOOL WITH INFLOW CONTROL |
摘要 |
An apparatus for fluid treatment of a borehole, the apparatus allowing initial outflow injection of fluids into a wellbore in which it is installed and then is actuable to allow fluid inflow control. The apparatus includes: a tubular body, a first port and a second port opened through the wall of the tubular body, the second port having a fluid inflow controller positioned to control the flow of fluid into the tubular body through the port, a sliding sleeve valve in the tubular body moveable from (i) a first position closing the first port and the second port to (ii) a second position closing the second port and permitting fluid flow through the first port and to (iii) a third position closing the first port and permitting fluid flow through the second port; a sleeve actuator for actuating the sliding sleeve valve to move from the first position to the second position in response to a force applied thereto; a releasable lock for locking the sliding sleeve valve in the first position and selected to maintain the sliding sleeve valve in the first position after the force is removed; and a lock release mechanism configured to actuate the releasable lock to release the sliding sleeve valve to move into the third position. |

1. An apparatus for fluid treatment of a borehole, the apparatus comprising: a tubular body having a long axis and an upper end, a first port opened through the wall of the tubular body, a second port opened through the wall of the tubular body, the second port axially offset from the first port and having a fluid inflow controller positioned to control the flow of fluid into the tubular body through the port, a sliding sleeve valve in the tubular body moveable from (i) a first position closing the first port and the second port to (ii) a second position closing the second port and permitting fluid flow through the first port and to (iii) a third position closing the first port and permitting fluid flow through the second port; a sleeve actuator for actuating the sliding sleeve valve to move from the first position to the second position in response to a force applied thereto; a releasable lock for locking the sliding sleeve valve in the first position and selected to maintain the sliding sleeve valve in the first position after the force is removed; and a lock release mechanism configured to actuate the releasable lock to release the sliding sleeve valve to move into the third position, |
