Description

Technical Field

[0001] The invention belongs to the technical field of drilling engineering and manifolds, and in particular relates to a throttling manifold with dynamic balance and shock absorption. Background Art

[0002] The choke manifold is a necessary device for controlling well kick and implementing oil and gas well pressure control technology. When the blowout preventer is closed, the opening and closing of the choke manifold is used to control a certain casing pressure to maintain the bottom hole pressure slightly greater than the formation pressure, so as to prevent the formation fluid from flowing further into the well; in addition, when shutting in the well, the choke manifold can be used to release pressure to achieve soft shut-in. When the pressure in the well rises to a certain limit, it is used to release the blowout to protect the wellhead.

[0003] At present, the throttling manifold needs to adopt the corresponding internal structure to perform small-amplitude buffering when performing buffering, but the existing throttling manifold structure often cannot achieve small-amplitude buffering. When the medium flow rate in the manifold is fast, the medium hits the corner of the manifold, causing the manifold to shake greatly, resulting in poor buffering effect, which not only increases the load of the throttling manifold shaking, but also reduces the service life of the throttling manifold structure, which is not conducive to the buffering effect of the throttling manifold.

[0004] Based on the above problems, the present application proposes a throttling manifold with dynamic balance shock absorption, which absorbs the impact energy of high-speed fluid through the setting of a first elastic shock-absorbing core and a second elastic shock-absorbing core, thereby reducing the vibration of the manifold, reducing the load of the manifold shaking, and achieving a buffering effect.
