Casing action: A casing is a pipe as a supporter that transports crude oil and natural gas from a reservoir to a surface after drilling is completed to withstand the pressure generated during the mining process.
Commonly used material: J55,K55,L80,N80-1/Q,P110,C90,C110,Q125
Delivery status: rolling plus normalizing
Casing pipe function:
Surface casing: The casing head is installed at the top, and the subsequent casings are suspended and supported by the casing head; the shallow water layer and the shallow complex bottom layer are isolated, and the fresh water layer is not contaminated by the drilling fluid.
Intermediate casing (technical casing): a layer that isolates different formation pressures or complex formations that are prone to collapse.
Production casing: protects the production layer and provides access to oil and gas from the production layer to the ground.
Drilling Liner: Reduces the load on the rig and the load on the casing head after cementing, while saving a large amount of casing and cement and reducing cementing costs.
Anti-adhesive buckle---allow multiple shackles
High dimensional accuracy, uniform organization and good toughness;
The product has excellent anti-squeezing and anti-explosion properties.
