Abstract

The invention provides a multifunctional well killing and blowout manifold. Including four-way, three-way, manual throttle valve, flat valve and one-flow valve; the two interfaces of four-way A are respectively connected with flat-plate valve A and flat-plate valve D, and the other two interfaces of four-way A are reserved; the above-mentioned flat Valve A is also connected with one interface of three-way A; the other two interfaces of three-way A are respectively connected with plate valve B and one-flow valve; plate valve B is also connected with one interface of four-way B; four-way B The other interface of the valve is connected with the plate valve C, and the other two interfaces of the four-way B are reserved; the above-mentioned plate valve D is also connected with one interface of the three-way B; the other two interfaces of the three-way B are respectively connected with the manual throttle valve. Connect to flat valve C. The invention has the advantages of reasonable and compact structure, few connecting parts, small occupation space, safe and reliable operation, combining the existing killing manifold and choke pipe into one, convenient operation, and has the advantages of well killing, blowout, positive and negative circulation washing. Well and other functions.

Description

technical field [0001] The invention belongs to the technical field of petroleum machinery, and in particular relates to a multifunctional well killing and blowout manifold. Background technique [0002] In the production and operation of oil and gas wells in oil fields, in order to prevent sudden accidents such as well kicks and blowouts, and to achieve effective control of oil and gas well pressure, it is necessary to be equipped with choke and kill manifolds. In the existing choke and kill manifolds, the choke and kill manifolds are connected separately, and are respectively connected to both sides of the large inlet cross that is connected with the blowout preventer. [0003] The main function of the choke manifold is to realize choke kill and blowout, and to adjust the pressure difference between drilling pressure and casing pressure. At the same time, the throttle valve is used to effectively control the pressure of the casing at the wellhead and the standpipe, so as ...
