Exploitation and understanding of Lianglitage Formation Upper Ordovician,southwest of Tahe Oil Field

Accumulations in the Upper Ordovician Lianglitage Formation in the southwest of Tahe OilField are mainly controlled by tectonics,fractures and karst effects.Based on the characteristic analysesof producing wells,hydrocarbon resources have been proved relatively rich in some regions in the south-west of Tahe Oil Field.The Lianglitage Formation has become the key reservoir in the region as explo-rations expand.The well regions of T705,T739-T740,5106 and TP7 have big potential,especiallythe T739-T740 and TP7 regions.
