摘要
准噶尔盆地腹部的石南31井区,下白垩统清水河组一段为一个近期新发现的以岩性控制为主的高产油藏。主要发育辫状河三角洲沉积,浅湖沉积次之,共识别出10种沉积微相、3个层序界面,可划分出2个三级层序。研究区存在两大物源区:一为东南方物源区,一为北方物源区。
A high production reservoir mainly controlled by lithology has been recently discovered in the Member 1 of the Qingshuihe Formation(K_1q_1)at the Shinan 31 Well in the central Junggar Basin.The production reservoir consists of braided river delta sediments and lacustrine sediments.We have identified 10 sedimentary microfacies,three sequence boundaries,and two third-order sequences in the Qingshuihe Formation.There are two important sediment provenances in the southeast and northern regions.
