疏松砂岩稠油油藏适度出砂开采方式研究

针对疏松砂岩稠油油藏的实际情况,在常规防砂和出砂冷采的基础上,提出了适度出砂开采方式。论述了适度出砂开采技术的增产原理,以及适合适度出砂开采方式的油藏条件。列举了一些国外油田的应用实例,进一步证明了适度出砂开采可以大幅度地提高油井产量。最后讨论了应用适度出砂技术应解决的几个关键问题。

Study on Reasonable Sand Producing Process for Unconsolidated Sandstone Heavy Oil Reservoir

This paper proposes the reasonable sand producing process for unconsolidated sandstone heavy oil reservoir, based on conventional sand control and cold flow production process, including its principle for stimulation and reservoir conditions suitable for this process. Through some cases abroad for its field application, it is proved that this process is of advantage of obviously improving oil production. Finally, this paper discusses several critical problems that should be paid attention to in application of this process.
