摘　　要：鄂尔多斯盆地三叠系延长组长2油层组作为靖边郑石湾区的主力含油层位,目前已处于开发晚期,存在水窜现象,导致部分油井高产水,影响注水开发效果。因此,有必要对该区长2沉积特征进行进一步的研究分析,以调整开发方案,提高产量。Triassic Yanchang formation Chang 2 in Jingbian district of Zhengshiwan group in Erdos basin,as main oil-bearing formation,is now in the late stage of development; there is water channeling phenomenon,resulting in some wells high water production to affect the water injection development effect. Therefore,it is necessary to carry out further research on the Chang 2 sedimentary characteristics,in order to adjust the development plan,increase the production..
