摘要
巴塔玛依内山组在卡拉麦里山(早期称克拉美丽山)南麓分布于双井子地区和火烧山北地区,是一套火山岩、火山碎屑岩夹沉积岩。双井子地区巴塔玛依内山组出露层序多而厚度大,可分为3个大的喷发旋回,8个岩性段,向南、北出露层序少且厚度小。火烧山北地区老山沟出露层序较全,厚度也较大,向西到五彩湾层序逐渐减少,厚度也相应减薄,在白碱沟巴塔玛依内山组底界应向南移约1 500 m.与下伏地层以超覆不整合接触为主。研究其岩性特征与厚度变化对滴西—五彩湾—沙帐—大井地区井下地层划分及油藏评价有重要意义。
The Batamayineishan formation in south foot of Kelameili mountain in Junggar basin distributed in Shuangjingzi area and northern Huoshaoshan area is a suit of volcanic rocks,pyroclastic rocks intercalated with sedimentary rocks.In Shuangjingzi area,there are several outcrops with big thickness of Batamayineishan formation,which can be divided into three eruption cycles and eight lithologic segments,the outcrops and thickness are less and thinner towards south and north of it.In northern Huoshaoshan area,full Laoshangou outcrops are almost found,with bigger thickness,towards west to Wucaiwan area,the outcrops and thickness are less and thinner.In Baijiangou area,the bottom boundary of Batamayineishan formation should be moved by about 1 500 m to the south,and dominated by overlapping unconformable contact with the underlying strata.This study about lithology and thickness variation is helpful for downhole formation division and reservoir evaluation along Dixi-Wucaiwan-Shazhang-Dajing areas.
