Automatic remote control liquid-driving blowout-preventing choke manifold

Abstract

The invention discloses an automatic remote control liquid-driving blowout-preventing choke manifold. The automatic remote control liquid-driving blowout-preventing choke manifold comprises a reducing five-way joint, an instrument connecting flange, a pressure gauge, a first manual flat gate valve, a second manual flat gate valve, a third manual flat gate valve, a fourth manual flat gate valve, a hydraulic choke valve, a manual choke valve, a first connecting pipeline, a second connecting pipeline, a fifth manual flat gate valve, a sixth manual flat gate valve, a first straight four-way joint, a second straight four-way joint, a third connecting pipeline, a fourth connecting pipeline and a reducing four-way joint. The lower end of the reducing five-way joint is connected with a drilling four-way joint via a blowout-preventing pipeline, the front end of the reducing five-way joint is connected with the pressure gauge via the instrument connecting flange, the left ends of the center lines of the reducing five-way joint are connected to form a remote hydraulic control part, and the right ends of the center lines of the reducing five-way joint are connected to form a manual control part. Operation efficiency can be improved, operation safety coefficient is increased, and operation cost is reduced.

Description

Technical field [0001] The invention relates to a well control device for petroleum machinery, in particular to a remote automatic control liquid drive blowout prevention choke manifold. [0002] Background technique [0003] During the drilling of oil and gas wells, once the drilling fluid in the wellbore is infested by the formation fluid, the balance between the static column pressure of the drilling fluid and the formation pressure will be disrupted, resulting in overflow and kick. The traditional choke manifold structure is too simplified. With the rapid development of drilling technology, the traditional choke manifold device can no longer meet the needs of drilling technology in the new era, that is, some parts of the traditional choke manifold device are in modern use. It has not been used, and the components required by modern drilling technology are not available on the traditional choke manifold. In addition, traditional choke manifold devices generally adopt a single-...

Problems solved by technology

The structure of the traditional choke manifold is too simplified. With the rapid development of drilling technology, the traditional choke manifold device can no longer meet the needs of the drilling technology in the new era. It is no longer used, and the components required by modern drilling technology are not available on traditional choke manifolds.

In addition, traditional throttling manifold devices generally adopt a single-wing structural design, which has low operating efficiency, high operating costs, and high maintenance costs, which cannot better meet the needs of the times.
