摘要
研究主要分压后尽早返排的理论依据及现场措施 ;排液后合理工作制度研究及压后配套油藏管理措施 3部分。如能同时落到实处 ,必能最大限度地发挥水力压裂的应有潜力 ,更好地为油田的稳油控水和各种综合治理服务。文中对此作了系统论述 ,并给出矿场实例分析。实例结果表明 ,通过检泵或换泵 (相当于放大生产压差 ) ,确实可以起到稳油降水效果。
A scientific management mode of post-fracturing wells is put forward in the paper.The key points are:(1)The theory of flowing back earlier and the corresponding measures applied in field cases;(2)study the rational production parameters which may be helpful to maximize oil daily rate after hydraulic fracturing and (3)study a scientific reservoir management mode especially for injection wells which may be needed to take corresponding measures such as matrix acidizing or hydraulic fracturing in order to get a suitable daily,injection rate.If above three measures can realize at the same time,anexpected maximum fraturing effect may be available.In the end,a field case is used to verify above conclusions.And the result indicates that it is really significant to stabilize oil rate and decrease water cut in the meantime by virtue of checking or changing the size or style of the production pump.
