Offshore self-propelled rush-installed wellhead operator

Abstract

The invention discloses a maritime self-propelled wellhead installing operation device. The maritime self-propelled wellhead installing operation device is characterized by comprises sliding systems, a wellhead centering mechanism and a cooling system; the sliding systems comprise the X-direction sliding system and the Y-direction sliding system. The X-direction sliding system comprising platform sliding rails and two sliding supporting legs slidably connected to the platform sliding rails on two sides of a wellhead correspondingly through sliding mechanisms. The Y-direction sliding system comprises a supporting seat connected to the two sliding supporting legs in a lapping mode and a base slidably connected to the upper portion of the supporting seat in the length direction of the supporting seat. The wellhead centering mechanism comprises a bottom lifting system, a top adjusting device, a new wellhead, a centering bell mouth and an ignition cylinder. The cooling system comprises a water tank, a ball valve, a water pump, a cooling water pipeline and a spraying nozzle.

Description

technical field [0001] The invention relates to an offshore self-propelled emergency installation wellhead operating device, which belongs to the technical field of equipment manufacturing for offshore oil and gas well blowout out of control fire and fire emergency installation of new wellheads. Background technique [0002] During the drilling of offshore oil and natural gas, once an oil and gas well blows out and catches fire, especially when a gas well with high hydrogen sulfide content catches fire, the original wellhead control device will be severely damaged. In order to protect the ecological environment, reduce environmental pollution and reduce life If the fire is put out first, the crude oil or natural gas with hydrogen sulfide emitted from the well will cause serious pollution to the environment. For this reason , developed a self-propelled offshore wellhead operator. The existing technical problem is: when installing a new wellhead with the current rush-installe...

Problems solved by technology

[0002] During the drilling of offshore oil and natural gas, once an oil and gas well blows out and catches fire, especially when a gas well with high hydrogen sulfide content catches fire, the original wellhead control device will be severely damaged. In order to protect the ecological environment, reduce environmental pollution and reduce life If the fire is put out first, the crude oil or natural gas with hydrogen sulfide emitted from the well will cause serious pollution to the environment. For this reason , developed a self-propelled offshore wellhead operator

The existing technical problem is: when installing a new wellhead with the current rush-installed wellhead operating device with fire, the staff needs to operate at close range at the burning wellhead. Due to the high temperature of the burning wellhead, especially for natural gas wells containing hydrogen sulfide, the wellhead The temperature is high, the fire is fierce, and the heat radiation is strong, which has a great impact on the mechanical properties of the components of the emergency installation device; the requirements for the structural performance and high temperature protection of the emergency installation device are extremely high, and there are hidden dangers; the safety of emergency personnel cannot be guaranteed
