浅论油田压裂技术和压裂液的优化选择

目的：针对不同储层性质，选用压裂技术系列中的不同压裂方式，使压裂效果达到最佳。方法：对压裂技术系列中的数种压裂工艺和与之配伍的压裂液的特性、技术关键点及对压裂层的预处理技术分别作了论述和对比。结果：压裂技术是低渗油层改造的重要措施，选准适合油层特点的压裂技术是压裂作业成功的先决条件。结论：低渗透、薄油层是压裂作业的主要对象，压裂前后对压裂井的地应力测井、裂缝监测技术及综合测井资料分析是至关重要的，对即将投入开发的低渗油田，整体压裂改造开发效果会更好，压裂井油层防污染保护和套管保护是压裂作业成功与否的关键点。

Optimizing Choice of Fracturing Technique and Fracturing Fluid in Oilfield

Purpose Selecting different fracturing ways in accordance with special reservoir nature, to make post fracture response optimal. Method We discuss and compare that such as many kinds of fracturing technology and the properties of fracturing fluid matched with the technology, technical keys and technical requirements of ahead fluid preprocessing and so on. Result Fracturing technology is important measures for us to transform low permeability reservoirs. Selecting actually fracturing techonlogy adapted to pay zones is the precondition to get success in fracturing operation. Conclusion Low permeability and thin oil beds are major objects.Ground stress log in fractured well, fracture monitoring techniques before and after fracturing and analysing comprehensively log data are all critical. For the low permeability oil field which will be started developing, the development results with whole fracturing can be much better. Preventing pay zones from pollution and casing protection are key factors that the fracturing operation succeed in or not.
