白音查干探区位于内蒙古西部巴彦淖尔盟乌拉特中旗境内,北临中蒙边界,南临阴山,海拔1100～1400m,该地区岩石胶结疏松,地层倾角大,小断层分布广,岩性多变,易垮塌,主要含油层位为都一段Ⅱ砂组,其次为都一段Ⅳ砂组,埋深浅一般在300-600m,压实及其成岩作用强度较弱,油层胶结较疏松。并且是水平稠油热采井,这给固井带来了一系列的难题。
The Baiyinchagan exploration area is located in the Walatianzhong Banner of Bayannur League in western Inner Mongolia. It borders on the border between China and Mongolia to the north and Yinshan to the south at 1100 ~ 1400m above sea level. The area is characterized by loose cementation, large dip angle and wide distribution of small faults Changeable and prone to collapse. The main oil-bearing layer is a section of Ⅱ sand group, followed by a section of Ⅳ sand group, the depth of which is generally 300-600m, compaction and diagenesis intensity is weak, and the oil layer cementation is loose. And is a horizontal heavy oil thermal recovery well, which brings a series of problems for cementing.
