Abstract
The CBL-VDL, SGDT-MAK Ⅱ and SBT log tests about cementing quality are made respectively in the No. 1 and No. 2 simulated wells in scale well group to estimate influence of lithologies on these logs when the cementing quality is better. Comparison between these log data and different circumference lithologies in the No. 1 and No. 2 wells indicates that when the cementing quality is better, the CBL is less influenced by the lithology; VDL is much influenced by the lithology; When cementing quality of boundary-Ⅰ is better, fast formation wave and casing wave may stagk, which makes CBL value increase, so different evaluation standards should be used for different lithology profiles when making quantitative evaluations; When the cementing quality of boundary-I is not good, the formation wave may be found in fast formation due to boundary-Ⅱ cementing influence. Different lithologies should be correspondingly corrected because SGDT and SBT logs are much influenced by the lithologies in cementing quality evaluations.关键词
