摘　　要：柴西南区是柴达木盆地石油勘探的主要区域,石油资源量为15.35×108 t,目前已探明石油地质储量3.53×108,整体探明率低,勘探潜力大,目前发现以构造油藏为主。随着勘探程度的提高和勘探技术的进步,岩性油藏勘探正逐步成为该区主要的勘探领域。油气地质评价表明,柴西南区发育河流三角洲体系控制的古近-新近系碎屑岩岩性油藏,勘探领域广阔,具有良好勘探前景。近几年在红柳泉E31油藏、乌南N21油藏、昆北E1+2油藏等地区的岩性勘探取得了良好成效,由此形成了比较成熟的勘探思路和方法。The south area in western Qaidam basin is a main area for petroleum exploration in Qaidam basin,with petroleum resources of 15.35×108t and proved OOIP of 3.53×108 t,which shows that it is in low identified rate and great potential for prospecting.The reservoirs discovered up to now are still dominated by structural reservoirs.With the increase of the explorative extent and the advancement of explorative technology,lithological reservoir exploration is becoming the major domain for petroleum exploration in this area.The petroleum geologic evaluation suggests that the south area in western Qaidam basin develops clastic lithologic reservoir of Tertiary controlled by fluvial delta system,being of broad domain and bright prospect for petroleum exploration.In recent years,the lithologic exploration achievements in such areas as Hongliuquan E31 reservoir,Wunan N21 reservoir and Kunbei E1＋2 reservoir support this mature idea and method for further petroleum exploration here.
