Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described further in the following with reference to the drawings and specific embodiments.
Specific embodiment, as shown in Figure 1, a kind of setting cementing unit of casing head, including the set that is once connected to from bottom to up
The both sides of tube head 10, drilling spool 2, preventer 1 and slurry conduit 11, drilling spool 2 are connected to kill-job by the second valve 3 respectively
Manifold 5 and choke manifold 12 further include cycle four-way, first circulation pipeline 9 and second circulation pipeline 13, first circulation pipeline 9
It is made of flexible rubber hose with second circulation pipeline 13, cycle four-way is connected to two valves up and down of casing head 10, first circulation
Pipeline 9 is connected to by the first valve 15 in the left and right sides of cycle four-way, first circulation pipeline 9 respectively with second circulation pipeline 13
It is connected to well cementation valve 6 by the first threeway 7 with second circulation pipeline 13, by the between kill manifold 5 and the second valve 3
Two threeways 4 are connected to, and well cementation valve 6 is connected to the second threeway 4, and the first threeway 7 is reducing tee, the large flange end of the first threeway 7
Mouth is connected to well cementation valve 6, and the small flange port of the first threeway 7 connects with first circulation pipeline 9 and second circulation pipeline 13 respectively
It is logical.
It is both provided with union 8 in the junction of first circulation pipeline 9, second circulation pipeline 13 and the first threeway 7, first
Pipeloop 9, second circulation pipeline 13 and the junction of cycle four-way are both provided with union flange 14,9 He of first circulation pipeline
The internal diameter of second circulation pipeline 13 is 75mm, and the large flange internal diameter of the first threeway 7 is 103mm, and small flange inner diameter is 65mm, second
Valve 3 and the latus rectum of the second threeway 4 are 103mm, and the small flange port for the first threeway 7 that two latus rectums are 65mm converges to latus rectum
The large flange port of 103mm, increased flow capacity can mitigate the pressure of pipeline, avoid building the pressure, and accelerate the speed of mud cycle.
When the utility model is used, first by drilling company drilling well, in kill manifold 5, the second threeway 4 and well cementation valve
