摘要: 库车前陆盆地发现的气藏类型多为高压气藏,且气藏埋藏深(一般大于 3 500 m),地层压力高,井身结构复杂,套管结构多为双层或多层套管。随着克拉、迪那及英买力等气田相继投入开发,对高压气藏的固井质量评价提出了更高要求。针对高压气藏的地质和工程特点,通过对比分析不同测井系列固井质量评价方法,优选出分区水泥胶结测井作为测井固井质量资料采集的首选系列。总结了在双层套管和高压气藏气侵等情况下固井质量的评价方法,提高了测井固井质量评价的精度,为克拉、迪那等高压气田的固井质量评价提供了技术支持。

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
