Abstract: The gas reservoirs discovered in Kuqa foreland basin are almost abnormal pressure reservoirs with deep burial (over 3 500 m in general), high pressure, complicated hole structure and equipped with dual or multiple zone casing. With bringing into development/ production of Kela, Dina and Yingmaili gas fields one by one, much higher requirement is needed for such a cementing quality evaluation. In view of the geological and engineering characteristics of abnormal pressure gas reservoirs, the comparison and analysis of methods for cementing quality evaluation in different logging series are conducted, followed by selecting segmented bond tool (SBT) as a premium series. Also, the evaluating methods for cementing quality of dual-zone casing and gas invasion in high pressure gas reservoirs are reviewed in order to provide technological support for evaluations of cementing quality in Kela and Dina gas fields, including making development scheme and realizing safe and stable production of them.

Key words: high pressure gas pool, cementing quality, SBT, logging evaluation
