摘要
在参考国外海相页岩气储层改造标准的基础上,结合鄂尔多斯盆地延长组陆相页岩气储层的特点,通过对页岩气储层改造方式、增产机理、区域层位选择三方面论证,提出了压裂液体系优化、支撑剂优选、施工参数优化、工艺配套技术优化的方案,逐步形成了一套适合延长组陆相页岩气储层的清水压裂改造工艺技术,并在延长油田多口页岩气井现场应用,获得了延长组陆相页岩气储层改造的一些认识。
In reference to foreign marine facies shale rock gas reservoir transformation standard,combined with the features of Yanchang formation continental facies shale rock gas reservoir in Ordos basin,according to the three aspects discussion as shale rock gas reservoir transformation mode,oil increment mechanism and regional layer selection,a design plan of fracturing fluid system optimization,proppant optimization,construction parameters optimization,matching technology optimization scheme has been proposed in the paper,which gradually formed a set of suitable sliding water fracturing technology for extended group of continental facies shale rock gas reservoir,and has some field application on several shale gas wells in Yanchang oilfield,and obtain some understanding on reservoir reconstruction of Yanchang formation continental facies shale.
