The specific embodiment
The utility model monolithic throttle well killing manifold operation embodiment is as follows:
Effect: as the corollary equipment of hydraulic blow out preventer, the control well stream that gushes out is implemented oil gas well pressure control technology, disposes the control pivot that surges, and can realize Long-distance Control.
The major function of choke manifold (1) is the control casing pressure, keeps the borehole pressure equilibrium relation; By the choke valve pressure release to realize soft closing; Can carry out open flow with the protection well head.
The main effect of kill manifold (2) is to pump into heavy drilling fluid with the balance bottom pressure in well; Can carry out open flow and discharge bottom pressure; Also can carry out the water filling well-flushing, annotate special operations such as extinguishing chemical.
Concrete operations:
1, closes the 2 place's flap types (14) and the middle manual flap type in main channel (18) of kill manifold (2) of surge in the choke manifold (1) choke valve (13) and manual throttle valve (17) upstream under the normal condition, choke valve is in semi-closed state, and the manual flap type (6) in choke valve downstream is opened;
2, when overflow taking place, according to arts demand, opening choke manifold (1) middle plateform valve (14) earlier slowly regulates the flow of the choke valve (13) that surges again and makes that fluid passes through choke manifold (1) middle plateform valve (14), the choke valve that surges (13), manually the outlet in flap type (6) and downstream is connected the outside release of assembly (7), to prevent well kick and overflow, reach pressure balance;
3, when 2 operations are not controlled well kick yet set by step, must open manual throttle valve (17), method of operating is with 2.
4, kill manifold (2) one ends link to each other with drilling spool (3) side opening, the other end links to each other with drilling mud pump, when bottom pressure can not pass through the drill string normal circulation, can pump into heavy drilling fluid by slush pump, enter flap type (14) by flap valve (16) and finish kill job from drilling spool (3) to the down-hole by the manual flap type in main channel (18) again.
5, when needs carry out special operation, as well-flushing, fire extinguishing etc., its method of operating is with 4, and the medium difference that just pumps into is clear water or extinguishing chemical.
6, surpass design pressure when borehole pressure; wellhead assembly may run under the situation of destruction at any time; must carry out direct open flow; at this moment; open the manual flap type in main channel (18) of the manual flap type of main latus rectum (6) and kill manifold (3) in choke manifold (1) the middle plateform throttling combination valve (4), open flow is with the protection well head simultaneously.
