【摘要】：为了进一步搞清楚塔里木盆地石炭系各个层系烃源岩发育的规模,达到对石炭系烃源岩深入研究的目的,对石炭系卡拉沙依组碎屑岩开展了有机质丰度、厚度、分布范围以及有机质类型和成熟度研究。结果表明,卡拉沙依组砂泥岩段发育的时期是卡拉沙依组优质烃源岩发育最重要阶段;卡拉沙依组砂泥岩段o_湖相分布的区域,即以玛参1井为中心的玛扎塔格构造带附近是优质烃源岩分布最好的区域,甚至优于塔西南山前带,在这一区域中有机碳含量大于2%,厚约60 m,处于低成熟-成熟的过渡阶段。但是,总体上看,塔里木盆地卡拉沙依组优质烃源岩分布相对局限。
[Abstract]:In order to further understand the development scale of Carboniferous source rocks in the Carboniferous series in Tarim Basin and to further study the Carboniferous source rocks, the abundance and thickness of organic matter have been developed for the Carboniferous Karashai formation clastic rocks. The distribution range, organic matter types and maturity are studied. The results show that the development period of sandstone and mudstone in Karashai formation is the most important stage in the development of high-quality hydrocarbon source rocks of Karashai formation, and the distribution of olake facies in the sandstone and mudstone member of Karashai formation is also the most important stage. In other words, near the Mazatag structural belt centered on Machan 1 well, the best distribution of high quality hydrocarbon source rocks is found, even better than the front belt of the Taxinan Mountains. In this area, the organic carbon content is more than 2 and the thickness is about 60 m.It is in the transition stage of low maturation to maturity. However, on the whole, the distribution of high quality hydrocarbon source rocks of Karashai formation in Tarim Basin is relatively limited.
