To oil reservoir characteristic and production status in
Pucheng oilfield , coiled rod is tried out for reducing oilfield
development cost. Coiled rod is one special type of rod without
connector or alone connector , which has one special material
antiseptic layer in its surface. It has some characteristics such as
light , little elastic modulus , high intensity , defend eccentrically
worn and so on. Implement through the scene , this technology
improves the result of the pump and lowers the costs ,there are
