长庆油田侏罗系油层增产措施及其效果评价

Stimulant Measure and Efficiency Evaluation for Jurassic Formation in Changqing Oilfield.

经对长庆油田侏罗系油层地质特征、油水分布关系及高产因素的研究 ,提出了一系列适合油层特点的增产措施 ,即深穿透负压射孔求初产、复合射孔求初产、深穿透负压射孔 +爆燃压裂、复合射孔与爆燃压裂联作、挤KCl解堵、酸化解堵、小砂量解堵性压裂措施等 ,经现场实践 ,取得显著效果。

After researching the geology characteristics,water oil distribution and high production factors,a set of stimulant measures are bring forward.They include deep underbalance penetrating,deep underbalance penetrating combined with flammable fracturing,KCl blockage elimination,acid blockage elimination,a little sand fracturing etc.The field application shows that all these stimulant measure are useful to raise the oil recovery.
