本文研究的奥陶系良里塔格组位于塔里木盆地塔中地区中央隆起带,上奥陶统良里塔格组为一套稳定的碳酸盐岩台地沉积,碳酸盐岩单井相分析是碳酸盐岩沉积研究的基础,通过单井相分析来识别沉积旋回、解释沉积环境和建立研究区的精细相模式进而探讨储层发育的控制因素是当前碳酸盐岩沉积储层研究领域的热点。因此,对奥陶系良里塔格组进行单井相分析非常重要。
The Ordovician Lianglitage Formation studied in this paper is located in the central uplift zone of Tazhong area in the Tarim Basin. The Upper Ordovician Lianglitage Formation is a set of stable carbonate platform sediments. Carbonate single well facies analysis is carbon Based on the study of sedimentary facies of carbonate rocks, it is the hotspot in the research field of carbonate reservoirs to identify sedimentary cycles through single-well facies analysis, explain the sedimentary environment and establish the fine facies model of the study area, and then explore the controlling factors of reservoir development . Therefore, single-well phase analysis of the Ordovician Lianglitage Formation is very important.
