摘要： 运用有限元方法对柴达木盆地尕斯库勒油田跃灰1井区$E^2_3$油藏进行了古构造应力场数值模拟和裂缝预测,给出了主要油层分布段的古构造应力场及裂缝方位和密度分布特征。裂缝的方位在不同构造部位和不同的深度有一定的差别,剪切缝主要为北东东向和北西西向,横张裂缝主要为近东西向,纵张裂缝主要为近南北向。构造轴部和高部位裂缝比翼部和低部位发育,随着构造埋深的增加,裂缝发育程度增强。

Abstract: The numerical simulation and fractural prediction of paleotectonic stress field of $E^2_3$ reservoir in Wellblock YH-1 of Gaskula oilfield, Qaidam basin are made with finite element method, and the paleotectonic stress field of distributed main oil zones and their fractural orientation and density distribution characteristics are obtained. It shows that there exist differences of the fractural orientations in different tectonic parts and different depths, with NEE and NWW for the shear fractures, near EW for the lateral tension fractures and near SN for the vertical tension fractures. In axis and higher parts of the tectonic, fractures develop well than flank and lower parts, and with increase of the tectonic buried depth, fractures tend to more and more development.

Key words: Qaidam basin, Gaskula oilfield, reservoir, stress field, numerical simulation, fracture
