Ultrahigh-pressure kill manifold with throttling pipeline

Abstract

The invention discloses an ultrahigh-pressure kill manifold with throttling pipeline. The ultrahigh-pressure kill manifold with the throttling pipeline is composed of a main body structure, a plurality of supports and a fixing base, wherein the main body structure takes a five-way joint as a center, four horizontal side surfaces of the five-way joint are correspondingly connected with four uprightmanual flat valves, two longitudinal upright manual flat valves of the five-way joint are correspondingly connected with a one-way valve of which the outer end is provided with a blind flange to formcross-shaped distribution, the door-shaped throttling pipeline consisting of a lifting short section, one horizontal inclined manual flat valve, a manual throttling valve, a wear-resistant short section, two tee joints, a buffer pipe and the blind flange is connected between a vertically upward channel and a side surface of the five-way joint and one sides of the two transversely distributed vertical manual flat valves. The manual flat valves in the main body structure is a manual rising stem flat valve driven by a ball screw pair, the manual throttling valve is a manual wedge type throttlingvalve with a bevel gear driver, and the operation strength is reduced while the functions are increased.

Description

technical field [0001] The invention relates to a well killing manifold in petroleum machinery and oil and gas drilling and production equipment. Background technique [0002] With the depletion of shallow oil and gas resources and the advancement of science and technology, exploiting deep oil and gas resources has become the current and future work direction. With the deepening of the oil and gas field, the increase of the diameter of the equipment, and the increase of the working pressure, the valves on the equipment are more and more difficult to operate due to the increase of the switch resistance; Human power is almost impossible to operate. In addition, the existing kill manifold and choke manifold are used as a set, and each is responsible for its own responsibility; the kill manifold is responsible for delivering the kill fluid, and the choke manifold is responsible for adjusting pressure balance and blowout; however, ultra-high pressure The fluid in the flow will ...

AI Technical Summary

Problems solved by technology

With the deepening of the oil and gas field, the increase of the diameter of the equipment, and the increase of the working pressure, the valves on the equipment are more and more difficult to operate due to the increase of the switch resistance; almost impossible to operate with human power

In addition, the existing kill manifold and choke manifold are used as a set, and each is responsible for its own responsibility; the kill manifold is responsible for delivering the kill fluid, and the choke manifold is responsible for adjusting pressure balance and blowout; however, ultra-high pressure If the choke manifold fails or cannot adjust the downhole pressure, there is a great risk of blowout
