Description
Technical Field
The application belongs to the technical field of safety production in the petroleum drilling industry, and particularly relates to a safety pipeline system for conveying high-pressure fluid.
Background
In oil and gas wells, it is often necessary to employ technical means to increase production in order to increase production. One method is to inject fluids into the well at extremely high pressures, fracturing the producing formation, and the high pressure fluids fracture the formation by creating fractures, resulting in more free flow of hydrocarbons from the formation. This allows more oil and gas to be produced from the well.
The pipelines used for these operations must be able to withstand the high pressures of the fracturing fluid injected into the well. During fracturing operations, these pipelines are typically only temporarily connected to the wellhead. Even if the pipeline design is capable of withstanding high pressures, cracks in the pipe and connection failures can still occur. Due to the dangerousness of high pressure fluids, safety precautions must be taken to minimize the hazards created when a failure occurs. When a pipeline for delivering high pressure fluid to a wellhead breaks or a high pressure pipeline connection breaks, it may result in uncontrolled ejection or whipping of the pipeline, which poses a significant risk to surrounding personnel and equipment.
Technical methods are applied to the fracturing process of oil and gas wells to ensure the safety of high-pressure pipelines, and when the joints of the high-pressure pipelines break down, the movement of the separated high-pressure pipelines is limited, so that the possibility of injury or death of nearby workers is reduced. In some cases, these may be metal clamps fixed on both sides of the connection joint and fixed to the ground by metal anchors; or the steel wire rope is wound on the high-pressure pipe, and then the pipeline is fixed through the metal fixed ground anchor. The main drawback of these arrangements is the laborious handling of the protection device and the long time required for installing the fixing system.
