车古201潜山油藏完井方式研究

Research on Completion Methods in Chegu 201 Qianshan Reservoir

研究了国内外潜山油藏完井方式应用及其使用条件、井身结构的应用 ,针对车古 2 0 1油藏特点 ,论证了其对裸眼完井、筛管完井、尾管射孔完井、管外封隔器完井的适应性 ,通过对比研究 ,从更好地满足油藏工程、采油工艺、增产措施出发 ,选择出车古 2 0 1潜山油藏最合理的完井方式为尾管注水泥射孔完井 。

This paper studies completion types and its application conditions in Qianshan reservoir. Aimed at the characters of Chegu 201 reservoir, it respectively discusses the adaptability by using different completion methods, such as open hole, screened open hole, perforated liner and packer cementing method. It is considered through research that liner cementing method is the most reasonable one for Chegu 201 Qianshan reservoir in order to meet with the demands for reservoir engineering, production technology and stimulating measures. Meanwhile, it furnishes the acceptable well structures for this reservoir.
