Abstract
The utility model discloses a novel two killing manifold of two throttles, preventing spouting group, choke manifold and killing manifold including the well head, being fixed with the well head cross and fixing six logical pieces in well head cross below on the upper portion of well head, six upper portions that lead to the piece meet well head blowout preventer stack, six lead to and to be connected with four pipelines on the piece, and wherein a choke manifold is connected on respectively to two pipelines, connects a killing manifold on two other pipelines respectively, the place ahead that the pipeline has elbow department is equipped with the liquid generator that changes. The utility model discloses a 4 the throttle control circuit of way interconnection rationally shares choke manifold's heavy burden, and effectual reduction throttle kill job risk has improved the well control and has equipped the ability of resisting the well control risk, simultaneously, the grout of usable high -pressure well drilling system, well cementation system carries out the kill job, accomplishes partial well and formation testing work, has higher reliability.
Description
Technical field
The utility model relates to a kind of well casing and converges, particularly the two kill manifold of a kind of Novel double-section stream.
Background technology
Throttle kill manifold system is one of critical facility in well control device, is to control well kick with assuring success, and realizes necessity equipment of Oil/gas Well Pressure Control Technology.When flow is certain, by the pressure reduction regulating the aperture of choke valve to control choke valve two ends, thus balance downhole formation pressure to the certain back pressure in shaft bottom, prevent the generation of the accident such as well kick, blowout.So the effect of well control throttle kill manifold in safety in production is most important.But due to well control pressure large, drilling fluid erosion is strong, and often can cause the erosive wear of throttle valve core and choke manifold, erosion inefficacy and manifold that spool even can occur pierce through.
Utility model content
The utility model object provides a kind of Novel double-section stream two kill manifold, based on existing well control equipment condition, adopt double throttle, two kill-job layout, the design of the throttling control loop providing 4 roads interconnected, rationally share the heavy burden of choke manifold, effective minimizing throttle well killing operating risk, improves the ability that well control equipment resists well control risk.
Technical solution of the present utility model is achieved in that the two kill manifold of a kind of Novel double-section stream, comprise blowout preventer group, choke manifold and kill manifold, be fixed with well head four-way on the top of well head and be fixed on the logical block of six below well head four-way, the top of six logical blocks connects wellhead blowout preventor group; Described six logical blocks are connected with four pipelines, and wherein connection one choke manifold gone up respectively by two pipelines, and two other pipeline connects a kill manifold respectively; The front that described pipeline has elbow is provided with liquid change generator.
Improve further as the utility model, described liquid state changes generator and comprises swirl vane and swirl vane is flexibly connected the minor axis of in-line.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The two kill manifold of Novel double-section stream of the present utility model, by arranging the six logical blocks being connected with four pipelines under well head four-way, article four, pipeline connects double throttle manifold and two kill manifold respectively, the design of the throttling control loop providing 4 roads interconnected, rationally share the heavy burden of choke manifold, effective minimizing throttle well killing operating risk, improves the ability that well control equipment resists well control risk; Meanwhile, the cement paste of high pressure drilling system, cementing system can be utilized to carry out kill job, complete part well and formation testing work, there is higher reliability.Be provided with in the elbow of above-mentioned pipeline and liquid change generator, increase by a reverse vortex to fluid in advance, avoid producing strong eddy current, slowing down corrosion in elbow, raising pipeline application life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the two kill manifold of a kind of Novel double-section stream of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
The two kill manifold of a kind of Novel double-section stream in the utility model as shown in Figure 1, comprise blowout preventer group 1, choke manifold 2 and kill manifold 3, fix well head four-way on the top of well head, the top fixing the logical block 4 of one or six logical block 4, six in the below of well head four-way connects wellhead blowout preventor group 1; Described six logical blocks 4 are connected with four pipelines, and wherein connection one choke manifold 2 gone up respectively by two pipelines, two other pipeline connects respectively a kill manifold 3; The front that described pipeline has elbow 5 is provided with liquid change generator.By being fixedly installed the six logical blocks 4 being connected with four pipelines at well head four-way, article four, pipeline connects double throttle manifold and two kill manifold respectively, the design of the throttling control loop providing 4 roads interconnected, rationally share the heavy burden of choke manifold, effective minimizing throttle well killing operating risk, improves the ability that well control equipment resists well control risk; Meanwhile, the cement paste of high pressure drilling system, cementing system can be utilized to carry out kill job, complete part well and formation testing work, there is higher reliability.
The liquid generator that changes comprises swirl vane 6 and swirl vane 6 is flexibly connected the minor axis 7 of in-line; Fluid is after entering pipeline, and swirl vane 6 rotates under the impact force of fluid, thus makes fluid have an oppositely eddy current, avoids producing strong eddy current in elbow 5, thus slows down the corrosion of pipeline elbow 5, improves pipeline application life.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
