Description
Technical field
The utility model relates to oil and gas well drilling control head, particularly one three-dimensional ocean throttle kill manifold.
Background technology
At present, because in oil pumping in oil fields, thin oil, high-solidifiability oil well operation process, bottom pressure is high,
In drilling process, the pressure of formation fluid (oil, natural gas, water etc.) is greater than borehole pressure and pours in pit shaft, and from the phenomenon that well head uncontrolledly sprays, oily liquid in pipe is easily caused to produce overflow and then develop into blowout, the casualties that pressure huge during eruption and shock wave cause and property loss, cause safety and environmental protection accident; Gas blowout accident is then be a kind of extremely harmful drilling failure by gas blowout accident, once occur often serious consequence occurring, must take tight preventive action; Therefore, be necessary to provide a kind of well blowout preventing device that can carry out blowout prevention or draining process to oily liquid in pipe, overcome above-mentioned defect.
Utility model content
The utility model object provides a kind of three-dimensional ocean throttle kill manifold to overcome the deficiencies in the prior art, and effective Prevention of blowout, collects natural gas by retracting device simultaneously, recycles further.
For achieving the above object, the technical solution adopted in the utility model is: a kind of three-dimensional ocean throttle kill manifold, mainly comprises double ram type preventer, drilling spool, five-way block, raises pipe nipple, choke manifold and kill manifold; Connect double ram type preventer above drilling spool, below connects five-way block, and left connects choke manifold, and right connects kill manifold; Connect below described five-way block and raise pipe nipple, left one tunnel connects choke manifold, and another road, left connects pressure release exhaust system, and right connects kill manifold; Described pressure release exhaust system is made up of pressure release service depot, turbine apparatus, gas recovery pipe, external relief valve, described pressure release service depot is built-in with turbine apparatus, draw external relief valve above pressure release service depot, described relief valve outlet connects gas recovery pipe; Described pressure release exhaust system, by negative pressure drainage U-tube, is connected with rising pipe nipple side.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
One of the present utility model three-dimensional ocean throttle kill manifold, in oil pumping in oil fields, thin oil, high-solidifiability oil well operation process, natural gas in timely discharge formation fluid, effective control oil-feed overpressure is in effective range, in effectively pre-preventing oil pipe, liquid produces overflow, effectively avoids blowout serious consequence occurs, reduces casualties and property loss as far as possible, collect natural gas by retracting device simultaneously, recycle further; There is the beneficial effects such as energy-conservation, safe, efficient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is that one of the present utility model three-dimensional ocean throttle kill manifold is practical.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 be one described in the utility model three-dimensional ocean throttle kill manifold, mainly comprise double ram type preventer 1, drilling spool 2, five-way block 3, raise pipe nipple 4, choke manifold 5 and kill manifold 6; Connect double ram type preventer 1 above drilling spool 2, below connects five-way block 3, and left connects choke manifold 5, and right connects kill manifold 6; Connect ram preventer 1, drilling spool 2, five-way block 3 below five-way block 3, raise pipe nipple 4, choke manifold 5 and voltage rise height pipe nipple 4, left one tunnel connects choke manifold 5, and another road, left connects pressure release exhaust system 7, and right connects kill manifold 6; Described pressure release exhaust system 7 is made up of pressure release service depot 8, turbine apparatus 9, gas recovery pipe 10, external relief valve 11, pressure release service depot 8 is built-in with turbine apparatus 9, draw external relief valve 11 above pressure release service depot 8, described external relief valve 11 exports and connects gas recovery pipe 10; Pressure release exhaust system 7, by negative pressure drainage U-tube 12, is connected with rising pipe nipple 4 side.
In oil well operation process, when stratum liquid is by five-way block, position pressure reduction flows in pressure release service depot 8 by stratum liquid automatically, under turbine apparatus 9 duty that pressure release service depot 8 is built-in, formation fluid body in pressure release service depot 8 forms centrifugal vortex, is conducive to promoting to be separated stratum fluid pressure, by drawing the pressure release effect of external relief valve 11 above pressure release service depot 8, natural gas is exported by external relief valve 11 and connects gas recovery pipe 10, reclaims natural gas recycling; Under stratum liquid after pressure release forms expanded state situation in pressure release service depot, under valve opening state, utilize pressure reduction, stratum liquid after pressure release is passed back into by negative pressure drainage U-tube and raises in pipe nipple, utilize oil pipe internal pressure differences, benign cycle back and forth, discharges oily overpressure in time, and effective Prevention of blowout occurs; There is the beneficial effects such as efficient, energy-conservation, safety.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
