Description

Technical Field

[0001] The utility model relates to the technical field of throttling well-killing manifolds, in particular to a novel throttling well-killing manifold. Background Art

[0002] The choke manifold is a necessary equipment 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 throttle valve 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 further flowing into the well. In addition, when shutting in the well, the throttle 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. When the pressure in the well rises, the opening and closing of the throttle valve on the throttle manifold can be used to release the fluid in the well to control the casing pressure. When the casing pressure is very high, the gate valve can be used to release the blowout directly. The well-killing manifold is an important part of the oil and gas well pressure control equipment. Its function is: when it cannot circulate normally through the drill string, the drilling fluid can be pumped into the well through the well-killing manifold to achieve the purpose of controlling the well pressure. One end of the well-killing manifold is connected to the side hole of the drilling spool, and the other end is connected to the drilling mud pump.

[0003] For example, a new type of throttling and well-killing manifold is disclosed in Chinese patent (CN212716499U), including a base plate, electric push rods are fixedly installed on the left and right sides of the top of the base plate, and a mounting plate is fixedly installed on the top of the output shaft of the electric push rod. The new type of throttling and well-killing manifold, through the operation of the electric push rod, pushes the mounting plate to move up and down, so that the throttling manifold moves together, so as to facilitate the docking with oil and gas pipelines at different heights on site. During the movement of the mounting plate, the sliding rods on both sides move inside the plate groove, further limiting the throttling manifold to make it more stable during the movement. At the same time, during the movement of the mounting plate, the gear plate moves on the gear plate. When the electric push rod is stationary, the gear plate will be stuck inside the gear plate. The gear plate supports the gear plate, which can effectively relieve the pressure of the mounting plate on some electric push rods, thereby achieving the purpose of convenient adjustment.

[0004] The above scheme also has the following shortcomings: the above scheme is not convenient for adjusting the direction of the throttling pressure manifold. Since the throttling pressure manifold needs to be connected with the oil and gas pipeline during use, the direction of the throttling pressure manifold of the above scheme is fixed, and it is necessary to connect by adjusting the direction of the oil and gas pipeline, but the direction of the oil and gas pipeline is inconvenient to adjust. Based on this, a new type of throttling well-killing manifold is proposed. Utility Model Content
