The Study of Remaining Oil Distribution in Tazhong 4 Oilfield’s TZ402CIII Oil Group

Abstract:

With the deepening exploitation percent, underground water relations have become more complex and tap the oil field at stable yields is more and more difficult, thus make us develop in depth study about the remaining oil distribution become critical. The proved geological reserve is high and physical property is better in 402 block’s group CIII of Tazhong 4 Oilfield. Combined with current mining situation in TZ402CIII oil group and in order to proven the distribution of the remaining oil, we used common reservoir engineering methods, neutron lifetime logging data analysis over the years and sweep efficiency analysis from sealed coring wells to study in-depth current remaining oil distribution range in TZ402CIII oil group, which provide an important basis to further improve development effect, dig remaining oil, as well as secondary development and adjust tap the potential in TZ402CIII oil group.
