Description
Technical field
The present invention relates generally to the control of underwater well completion, and relates to the system and method for controlling for by the underwater well that landing sub (landing sub) is placed on the vertical subsea production tree (tree) particularly.
Background technology
The underwater well head assembly is generally used for producing the hydrocarbon that the subterranean strata under the seabed extracts.The underwater well head assembly comprises the well head case that is arranged on the well opening part substantially, and wherein, well extends through one or more nytron deposits yields rock stratum.Sleeve pipe and pipeline hanger are placed in the case so that sleeve pipe and the production pipeline in the well inserted in supporting.Sleeve pipe is to well lining the lining of well (or as), thereby well and on every side rock stratum are isolated.Pipeline is positioned at sleeve pipe usually with one heart and is provided for producing the conduit of the hydrocarbon that is attached in the rock stratum.Wellhead component also generally includes the subsea production tree (also claiming Christmas tree, christmas tree) that is connected to well head case upper end.Subsea production tree control and distribution produce the fluid from well.
By sending instrument (running tool) to latch in the production tree main spindle down or snap close is attached to down to exterior contour and with steel wire (wire) or drilling pipe and send instrument in order to subsea production tree is reduced to the well head case, subsea production tree is installed on well head case, pipeline head or the pipeline hanger four-way (spool).Then, one or more umbilical cord pipelines can be delivered to subsea production tree under working platform, umbilical duct can be connected to subsea production tree by the operated from a distance utensil in the case.These umbilical duct are used for installing production tree, reenter, well workover or well provide between the date of retirement power (hydraulic pressure and electronic) extremely under water control module control the functor of subsea production tree, for example flow control valve, restriction choke and other hydraulic means.In addition, umbilical duct can be used to be received in the operating period of subsea production tree from the information of production tree sensor.The end opposite of umbilical duct can be connected to the device at the water surface (surface) platform place, and other underwater units of operation control perhaps is provided as the alternative valve that is connected in the subsea production tree.These umbilical duct can be arranged on the submarine site place on following several miles of sea.One or more umbilical duct also can be used to sending too much pipeline hanger and connection fore-set (landing string) to carry out function or pressure test down.This system passes under the probing marine riser and delivers in well head or the production tree main valve piece.Therefore, umbilical duct can constitute temperature and the pressure that can stand in this type of position.And this cost that can cause this type of umbilical duct is high, surpasses millions of dollar and builds enough firm and long enough with the umbilical duct of the submarine site place use of standpipe outside under water.
These umbilical duct also may be damaged by spooling during operation.When umbilical duct is damaged, because umbilical duct must regain, repairs and make it to send down again, so operating cost significantly rises.Operating personnel can preserve standby umbilical duct and spool (reel) in order to solve sending into and the potential damage of operating period to this umbilical duct via umbilical duct.Again be that this can increase the cost of well operation and the additional facilities of the umbilical duct that need store for future use at the surface platform place significantly.Again furthermore, under the situation that offshore boring island (rig) can remove from pithead position, may need the management system of adding in order to preserve umbilical duct.This also can increase the cost of well operation significantly.
During work-over operation, can be with the well workover umbilical duct from floating offshore boring island or operation ship is fallen and will be connected to production tree from the lead-in wire of well workover umbilical duct.Additional umbilical duct also can be fallen with device with the instrument of well workover and completion.These umbilical duct to above-mentioned instrument and device provides electronic or hydraulic power in order in well head and production tree assembly, operate.The following of multiple umbilical duct that is used for underwater operation send because the four-way and the facility that need to add at the water surface support additional umbilical duct and increased running cost significantly.Therefore, a kind of system or method of using less umbilical duct to control subsea production tree need be arranged.
