| 摘 要： | 针对塔河油田1、9区为代表的碎屑岩油藏开发难题,开展系统调研论证,明确碎屑岩油藏先由单井吞吐储备技术基础,逐渐放大规模,进行井间气驱的发展思路,开展氮气泡沫吞吐。氮气密度低、不混相,擅长处理垂向矛盾;泡沫能提高吞吐效果。通过国内外文献调研及油田现场调研,对塔河油田1、9区碎屑岩油藏氮气泡沫吞吐进行了适应性研究分析。

| Abstract: | Aiming at problems in development of clastic rock reservoirs in No. 1 and No.9 blocks of Tahe oilfield, systematic research and demonstration were carried out. It＇s pointed out that, at first single well stimulation in the clastic rock reservoir should be carried out to reserve technology foundation, then development scale should be gradually enlarged to realize gas flooding between the wells, at last nitrogen foam huff and puff should be carried out. Nitrogen has low density, is not miscible, so it is good at treating vertical contradictions, the foam can improve the stimulation effect. In this paper, through research on correlative literatures and oilfields at home and abroad, adaptability of the nitrogen foam huff and puff technology for clastic rock reservoirs in No. 1 and No.9 blocks of Tahe oilfield was studied and analyzed. |
