摘要
尕斯E31油藏属于异常高压未饱和油藏,动态能量分析表明油藏具备一定的天然能量,边水能量较弱。投产初期产能为双曲递减规律,中后期递减加快表现为指数递减规律。油藏中后期分层调整后,存水率保持在0.80以上,水驱指数保持在1附近,含水控制较好,采收率能达50%以上,说明注水开发取得较好效果。
Gasi E31 reservoir pertains to unsaturated abnormal pressure reservoir,it shows that the reservoir possesses definite natural energy and that energy of edge water presents faint by dynamical energy analysis.Scaling down law expresses the situation that early day is twin and mid-late is index number.After layering regulation in mid-late period,it shows that exploitation effect is preferable for the indexes those extant water rate maintenances more 0.80,water flooding index maintain 1,water ratio is controlled relatively and recovery ratio will win more 50%.
