STUDY ON THE FEATURES OF DIFFERENT REFLECTION IN TAHE OILFIELD PALEOCAVES RESERVOIR/Jianfeng Wang, Pei Jin, Xinhua, Li et al. Northwest Oilfield Company of SINOPEC, Urumqi, Xinfiang ,830011/Xinfiang ShiYou TianRan Qi ,2011,7 （ 3 ） ： 1 - 5 rnAbstract：In This paper, in the light of Seismic migration section and tectonic analysis data, seismic echo styles of Tahe oilfield paleocaves reservoir in time migration are summed up; different reflection features are classified. In the meantime, the classification criteria of quantizing identification with reservoir seismic echo model is established. With those methods above, the paleocaves reservoirs forecasting degree and well arrangement ratio are improved, the risk of developmental drilling is reduced and efficiency is reduced. The high development efficiency in Ordovician paleocaves reservoir is fulfilled.rn Key Words ： Tahe Oilfield ; Paleocaves Reservoir; Reflection features ; Quantizing identification ; Reservoirs forecasting
