摘　　要：震旦-奥陶系白云岩是塔东北地区的主要储集岩,著名的沙参2井的高产工业油层即是奥陶系白云岩。本文探讨了震旦-奥陶系白云岩的储集特征、控制储集岩发育的主要因素,并对储层作了分层评价,预测了储层发育的有利地区,探讨了储层转化为油气层的可能性。The principal reservoir rocks in the northeastern Tarim Basin are composed of the Sinian-Or dovician dolomites,and the high productive oil reservoirs met by well-known drilling well Shacan-2 are attributed to the Ordovician dolomite system. In this paper, their reservoir properties and the controlling factors are approached. Furthermore, the evaluation of the individual layers of the reservoir and the prediction of favourable regions for the prospecting plays of oil/gas fields have been made in this paper.
