摘要(Abstract)：

凝灰质储层由于胶结松散,遇水易分散,基质含量高,孔隙发育程度和连通性差,勘探开发难度较大。以海拉尔贝16断块兴安岭油层为目标区块,从兴安岭群油层的物性与岩性特征入手,系统论述了兴安岭群黏土矿物分布特征并着重研究了储层的伤害机理与防治措施。矿场应用结果表明,筛选出的3种黏土稳定剂,QY-138号黏稳剂与凝灰质储层的配伍性最好。研究成果为海拉尔兴安岭凝灰质储层注水开发提供了理论指导。
Due to the relax cementation,easy to be separated characteristic when met with the water,high percentage of the matrix,well-developed porosity and poor connectivity of tuff reservoirs,the greater difficult exploration and development occur. Taking Xing 'anling oil reservoirs in Hailer Faulted Block 16 as the target,from the viewpoints of the reservoir physical properties and lithological characteristics,the distributing properties of the clay minerals in Xing'anling Group were systematically discussed and moreover the studies on the damage mechanism and preventing-controlling measures were emphasized. The field application results show that among the three kinds of the chosen clay stabilizers,No. QY-138 stabilizer possesses the best adaptability with the tuffaceous reservoirs. The achievements have provided the theoretical guide for the water injection development of Xing'anling tuffaceous reservoirs in Hailer Oilfield.
