摘要
随着油气田开发进入中后期,油井综合含水率上升,油田开发难度加大,为进一步提高采收率,需要对油藏流体相态进行深入研究。文中对克拉玛依油田五2西克下组T2K1块油藏流体进行了相态特征测试,通过单次脱气实验、PV关系实验、多次脱气实验等相态实验研究,获得了其相态特征。研究结果表明,该流体具有密度低、粘度低、膨胀性和收缩性小等特点;原油具有一定的溶解气量,属中等气油比原油;体积系数偏小,气体平均溶解系数一般;原油体积系数分布较集中,值较小。
As oil and gas field development entering mid-later period, total water cut of oil well is increased, oilfield development is becoming more difficult. For enhanced oil recovery, fluid phase behavior research is necessary. Phase behavior of reservoir fluid is studied in T2K1 block, Kexia formation, Wu2xi, Karamay oilfield. The research result shows that the oil reservoir has characteristics of low density, low viscosity, and low expandablity ,etc.
