| 摘 要： | 赛51井储层改造存在如下问题:①物性差基质基本不含油;②杨氏模量高,应力遮挡差;③储层温度低,破胶困难;④原油凝固点高,胶质和沥青质含量高,易结蜡;⑤酸液浓度高,对缓蚀要求高,需要采用深度酸压技术形成长缝等。在储层评价研究基础上,针对以上问题研究制定技术对策,应用地面交联酸体系施工获得成功。该井的施工成功开辟了二连盆地古生界灰岩潜山找油新领域,实现了我国东部地区石炭系灰岩潜山勘探的首次重要突破。

| Abstract: | On the basis of reservoir evaluation,problems appeared in reservoir treatment for Sai 51 is follows:1,poor physical property and almost no oil in matrix;2,the high Young's modulus,poor stress shielding;3,low reservoir temperature and difficulty of broken plastic;4,the high freezing point of crude oil,high content of resin and asphalt,easy to wax;5,high acid concentration,high requirement for corrosion and need to use the depth fracturing tech to built long slit,and so on.Countermeasures are studied and made... |
