【摘要】 压裂酸化技术在相当长的时间内仍将是油气田勘探和开发工作中提高油气井产能,提高油气藏采收率的重要手段。我国这方面的化学剂和国外先进产品比较存在显著差距,需要发展稠化剂、降滤失剂、降摩阻剂、保护地层的化学剂、暂堵剂以及酸化压裂用各种表面活性剂的研制和生产,以适应我国油气田勘探开发中新的工艺技术的需要。更多还原

【Abstract】 Hydraulic fracturing and acidizing remain an important way to increase the productivity of oil/gas wells and to enhance their rccovery. A comparision of the domestic chemicals used in these operations with the foreign novie products shows that there exists an obvious difference between them. It is necessary therefor to improve the properties and functions of these chemicals(such as gelling agents,leakoff additives, friction reducers,clay stabil- izers,diverting agents,and surfactants) to meet the requiments in accordance with the newer acidizing and fracturing techniques.更多还原
