针对研究区的区域地质概况,并借鉴了前人的研究成果,利用地震和测井资料识别出了三级层序边界,并对各层序进行了体系域划分,建立了研究区的等时地层格架.在此基础上,通过对岩芯和测井相的综合分析,以体系域为单位进行了沉积相的划分,建立了研究区的精细沉积相模型,并对沉积相的展布特征进行了分析.
針對研究區的區域地質概況,併藉鑒瞭前人的研究成果,利用地震和測井資料識彆齣瞭三級層序邊界,併對各層序進行瞭體繫域劃分,建立瞭研究區的等時地層格架.在此基礎上,通過對巖芯和測井相的綜閤分析,以體繫域為單位進行瞭沉積相的劃分,建立瞭研究區的精細沉積相模型,併對沉積相的展佈特徵進行瞭分析.

Microfacies is of great significance in oil field exploitation, because it determines the distribution of reservoirs and barriers of the flow and also controls the fluid flow difference of the reservoir sand. Researches on sedimentary facies are based on the accurate and precise stratigraphic framework model. According to geological characteristics and results of previous studies, the authors used seismic and logging data to identify the third-grade sequence boundaries and divided the sequence into systems tracts. On such a basis, the sequence stratigraphic framework of the study area was established, the sedimentary microfacies were divided, and the accurate sedimentary facies model of the study area was constructed through a comprehensive analysis of the single well and logging data.
