Twenty third-order sequences were recognized in Oligocene TB1. 1 to Quaternary TB3.9 strata. Based on the abundance and diversity of microfossils, assemblage characteristics, and estimated water depths, paleoenvironments were reconstructed for reservoir sandstones in $29-28 under the heme-font: minor-latin; mso-fareast-font-family: 宋体; mso-fareast-theme-font: minor-fareast; mso-hansi-font-family: calibri; mso-hansi-theme-font: minor-latin">＂fault No. 1heme-font: minor-latin; mso-fareast-font-family: 宋体; mso-fareast-theme-font: minor-fareast; mso-hansi-font-family: calibri; mso-hansi-theme-font: minor-latin">＂ zone. The study establishes a sequence stratigraphic framework and a sedimentary facies model for the Yinggehai-Qiongdongnan Basin.
