Keyword:  下二门油田稠油油藏稠油防砂化学降粘机杆泵优化;
Abstract: 下二门油田浅北区块为特稠油油藏,由于原油粘度高,地层胶结疏松、出砂严重,储层水敏严重等原因,2005年试采的四口井效果较差,主要表现在注汽效果差、油汽比低、出砂严重、泵效低等问题.针对地层的深、稠、松、敏的特点.配套集成了压裂充填先期防砂、隔热油管泣汽、防膨刺油层保护、地层和井筒降粘、机杆泵优化配套等措施,进行了四口井的先导试验.试验后油汽比由0.08提高到试验后的0.55,平均日产油由0.5 t提高到8.0 t,试验取得了很大的成功.对比评价效果,最终优选出经济有效的适应中深井疏松砂岩稠油油藏特点的技术,为河南稠油油田其它类似区块的高效开发提供依据.
