摘要
南堡陆地低渗油藏储层物性差,需要采取压裂开发方式才能有效动用。根据油藏储层特点,将南堡陆地低渗油藏分为三类,根据油藏特点分别研究了整体开发压裂技术、混合水压裂技术和压裂+吞吐技术,通过三种工艺技术形成了适用于南堡陆地油田完善的压裂工艺体系,在现场应用取得较好增产效果,也为其他低渗油藏的压裂开发提供了技术借鉴。
Fracturing is a necessary development method to achieve the purpose of effective utilization in Nanpu land low permeability reservoir caused of it negative reservoir property.According to the characteristics of the reservoir,it is divided in three types which named low permeabilityⅠ,low permeabilityⅡand low permeabilityⅢ,respectively.A perfect fracturing process system suitable for Nanpu land oilfield is formed by whole development of fracturing technology,mixed hydraulic fracturing technology and fracturing+huff and puff technology.It has been applied in the field to achieve a positive influence of simulation,as well as and it also it also provides technical guidance for fracturing development of other low permeability reservoirs.
