API 1-piece integral casing centralizer
Casing centralizer is one of the needed standard casing accessories, on effectively operationscompletion, the rational use of casing centralizer can play the position of:
Decreasing reduced casing resistance phenomenon, creating the casing easily down to the style placement
Generating casing centralizer centered inside the wellReducing the sticking phenomenon to make the annular space hydrostatic force well balanced
Decrease channeling, enhance the mud substitute efficiency, hence increase the cementing top quality.
Bow-spring centralizer
1.These centralizers are created for high restoring force and minimal starting power for centralizing the casing pipe in a vertical, horizontal and deviated effectively
2.Top quality high quality bows are made of specific alloy steel and hot formed in absolutely managed warmth remedy plant to accomplish the uniform hardness all above
three.Spec and efficiency index of bow spring casing centralizer meet api spec 10d.The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for practical storage and transportation.
Rigid roller centralizer
Rigid casing centralizer is utilized in deviated wells and horizontal wells.There are several blades on the rigid roller centralizerthat can preserve casing from making contact with the wellbore wall
