Hydraulic remote-control high pressure manifold for fracturing

Abstract

The invention discloses a hydraulic remote-control high pressure manifold for fracturing, and belongs to the technical field of hydraulic fracturing equipment. The hydraulic remote-control high pressure manifold comprises a right-angle two-way joint, a tee joint and a straight pipe for connecting the right-angle two-way joint with the tee joint, and further comprises a hydraulic-control plug valve system and a control box of the hydraulic-control plug valve system. The hydraulic-control plug valve system comprises a hydraulic pipeline, a plug valve, a hydraulic-control plug box, an electric pump, a storage battery, a hydraulic distributor and a hydraulic oil control valve controlled by the hydraulic distributor. The storage battery supplies power to the hydraulic-control plug valve system and the control box of the hydraulic-control plug valve system. The control box and a remote control system achieve real-time data transmission. The control box controls the electric pump to pump hydraulic oil to the hydraulic distributor according to an instruction of the remote control system or an on-site input instruction, the hydraulic distributor opens the hydraulic oil control valve of the target plug valve, and hydraulic oil drives the plug valve to be opened or closed. Local control or remote control can be achieved for the high pressure manifold, and operation safety and reliability of the high pressure manifold are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic fracturing equipment, and relates to a hydraulic remote control high-pressure manifold. Background technique [0002] During hydraulic fracturing construction, the sand mixer truck supplies fluid to the fracturing pump truck through the low-pressure manifold; the fracturing fluid pressurized by the high-pressure pump of the fracturing truck merges at the high-pressure manifold through the discharge end; the merged fracturing fluid passes through The high-pressure pipeline enters the wellhead, and enters the formation along the wellbore to create fractures and improve the conductivity of the formation. Among them, areas such as fracturing trucks, high-pressure manifolds, and high-pressure pipelines are high-pressure areas. In order to repair the pump truck, the operator usually closes the plug valve at the discharge end of the pump truck under high pressure, which poses a greater risk of personal...

Problems solved by technology

[0003] The existing high-pressure manifolds mainly use manpower to manually control the opening and closing of the high-pressure cock valves. Construction workers need to enter the high-pressure area to manually open the cock valves on the high-pressure manifolds to open or close the cocks. Serious threat, serious violation of HSE labor rules and regulations, misjudgment of the cock state during manual operation, resulting in construction accidents and construction failures, the accidents have a wide range of influence and serious consequences, and there is an urgent need for high-pressure manifolds that can be operated remotely
