Abstract

Abstract:

The mainly difficult problem of production inadequate return top of slurry and poor bonding cementing hole reaction are discussed in the paper; the effective factors of cementing quality – poor slurry property, lost circulation, poor displacement in long bare hole, and o8il-gas-water migration in the processes of slurry setting are analyzed; the technical countermeasure of enhancing cementing quality and preventing casing corrosive are presented. The previous troubles are solved satisfactorily and marked economic benefit abstained by using these techniques in low temperature, weak and oil-gas-water active formation.

Key words: Cementing quality, Casing, Corrosive control, Economic benefit, Changqing Oil Field
