Description
Technical field
The present invention relates to a kind of wellhead slurry reflux and drilling mud circulation test macro.
Background technology
After offshore boring island has been debugged maritime applications system and well system, according to certification (CDS) code requirement of steel ship construction rules (ABS) and well system, need to carry out combined debugging to drilling system, guarantee that in drilling process, mud can reflux smoothly.
As shown in Figure 1, mud during normal drilling operability in mud pit 100 drives 106 by slurry prime pump 101, high pressure slurry pump 102, mud standpipe manifold 103, mud standpipe 104, mud hose 105, top successively, drilling rod 107, well head 108, be sheathed on the mozzle 109 outside drilling rod 107 or be sheathed on marine riser outside drilling rod, be connected with mozzle 109 turn spray apparatus 110, mud return duct 111, scraper 112, slurry dispenser 113, vibrosieve 114, mud conditioning tank 115, mud overflow passage 116 after again return in mud pit 100.
But in order to ensure the normal work of whole well system, need to carry out mud circulation test to this system before formally carrying out drillng operation.As shown in Figure 2, in existing mud circulation test process, connect a preventer 108 ' in the bottom of mozzle 109, the order of connection of remaining part is identical with normal drilling operability in Fig. 1.In test process, define closed mud circulation loop after being closed by preventer 108 ', just can carry out mud reflux test subsequently.During pending formal drillng operation, removal preventer.
There is following shortcoming in existing mud circulation test:
1), need mozzle and preventer and control system thereof, require very high to project process.
2), due to the length requirement of mozzle and preventer, this test needs the marine site more than 50 meters of depth of water to carry out, and test request is harsh.
3), mozzle and lubricator self involve great expense, and preventer is delegated to below the water surface 50 meters, therefore tests very risky.
4), before preventer is connected to mud circulation test macro need the test carrying out the long period, cause the needs that cannot meet mud circulation test the time, incur loss through delay the testing time of the circulating system.
Summary of the invention
The technical problem to be solved in the present invention is that the preventer in order to overcome prior art involves great expense, testing time in early stage is long, mud circulation test macro can only be carried out under comparatively harsh environment, and operation risk is large, the defect that cost is high, provides a kind of wellhead slurry reflux and drilling mud circulation test macro.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of wellhead slurry reflux, its feature is, it comprises a tubing, the link that this tubing comprising for being connected with one turn of spray apparatus, opening wide, and the bottom that closes, and this bottom is provided with some reinforcing mechanisms.
Wherein, this link is provided with one and turns the flange of spray apparatus adaptation with this, this tubing and this turn spray apparatus by this Flange joint.
Wherein, the external surface of this tubing sets firmly and somely hangs horse.Describedly hang horse for lifting this wellhead slurry reflux to carry out installation or removal operation.
Wherein, this bottom is also provided with one along the base plate extended radially outwardly of this tubing.This base plate is used for strengthening this bottom, bears the impact to bottom when mud circulation is tested, to simulate shaft mouth operation truly.
Wherein, this reinforcing mechanisms is some brackets, the side of this bracket and this tubing affixed, the opposite side of this bracket and this base plate affixed.This bracket is used for strengthening this bottom, improves the holding capacity that bottom is impacted mud, to simulate shaft mouth operation truly.
Present invention also offers a kind of drilling mud circulation test macro, it comprises a slurry prime path and a mud current return circuit, its feature is, this slurry prime path is communicated with by described wellhead slurry reflux with this mud current return circuit, forms a mud circulation loop.
Wherein, this slurry prime path comprises and connecting successively: this slurry prime path comprises and connecting successively: a slurry prime pump be connected with a mud pit, a high pressure slurry pump, a mud standpipe manifold, at least one mud standpipe, at least one mud hose, push up to drive and drive to be connected with this top and extend to drilling rod in this tubing and drill bit from this link, and the top of this tubing is equipped with one turn of spray apparatus.
Wherein, this mud current return circuit comprises and connecting successively: turn with this at least one mud return duct, a scraper, a slurry dispenser, a vibrosieve, a mud conditioning tank, mud overflow passage be connected with this mud pit that spray apparatus is connected.
In the present invention, above-mentioned optimum condition can be combined on the basis meeting this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: the alternative preventer of wellhead slurry reflux of the present invention and mozzle carry out mud circulation test to drilling mud circulation test macro, drilling mud circulation test macro and preventer are synchronously tested, in addition do not need to install in advance mozzle and preventer and control system thereof yet, thus decrease stand-by period and the test risk of this test macro, reduce testing cost.Further, the structure of wellhead slurry reflux of the present invention is simple, simple installation, requires therefore be not subject to the impact of experiment marine environment without the depth of water.The testing cost of drilling mud circulation test macro of the present invention is low, test risk is little, because not needing to install in advance mozzle and preventer and control system thereof, is not thus subject to the impact of project process.
