1. Product Overview
The kill manifold is key equipment for oil and gas well pressure control and well-control operations. It is mainly used to pump heavy drilling fluid into the well when wellhead pressure rises, balancing bottom-hole pressure and reducing kick and blowout risks.
The product can be used with high-pressure pumps, flowback lines, and wellhead equipment for killing, flowback pressure relief, squeeze cementing, and injection of clean water or fire-extinguishing agents at the wellhead.
The check valve in the manifold controls one-way entry of kill fluid or other fluids into the wellbore and prevents backflow, meeting kill and pressure-control process requirements.
2. Design Features
Products are designed and manufactured according to relevant API 16C and NACE MR0175 requirements and are suitable for standard and sour service.
They can be used with high-pressure pump units and wellhead equipment for heavy drilling-fluid injection, flowback pressure relief, and well-control process switching.
Valves, check valves, and line layouts can be combined according to the field well-control process for quick operation and maintenance.
Special design and manufacture can be provided according to wellsite layout, pressure rating, and connection form.
