Products Description
A, DZ-RB-type thermal stress compensation purposes
DZ-RB-type thermal stress compensator is used in oil well casing thermal expansion, it can cut the pins,
Thereby compensating for expansion and contraction of a special apparatus casing, the casing at the yield stress limit of the control range.
Two, DZ-RB-type thermal stress compensator structure and composition
DZ-RB thermal stress compensation mainly by the outer cylinder, the inner cylinder, seals, a short section of casing, coupling components.
Three, DZ-RB-type thermal stress compensator main features
1, DZ-RB-type thermal stress compensator compensating effect is likely to replace pulling prestressing effect on some wells, it is often impossible pulling prestressing. According to the research that pulling on the thermal expansion stress prestressed have some effect, but the presence of residual stress on casing influential.
2, DZ-RB-type thermal stress compensator cementing technique is simple and conventional casing cementing no difference, it also applies to early completion, screenless common cementing techniques, especially for heavy oil thermal recovery horizontal wells. And no special technical requirements, ease of application.
Four, DZ-RB-type thermal stress compensator main technical parameters :
