针对陇东油田底水油藏特征，确定了水力喷射钻孔的合理位置；根据油田的实际油藏参数运用数学解析的方法，分析了影响水力喷射钻孔井产能的因素，研究了水力喷射钻孔技术对底水油藏的开发效果。结果表明，射孔孔深、射孔孔眼半径、射孔数和油层厚度等因素对油井的产能均有影响；水力喷射钻孔的孔深越深，射孔半径越大，射孔数越多，产能比就越大；且水力喷射钻孔技术在薄油层的开发效果好于厚油层。在底水油藏实施该项技术可以有效的控制底水锥进从而提高采收率。

The optimum location is determined aiming at the character of the bottom water reservoir in Longdong oilfield. Based on mathematical analysis method of oilfield factual da- tum, the affecting factors of productivity for hydraulic jet perforation well are analyzed, and the exploitation effect of bottom water reservoir by using hydraulic jet perforation technology is studied. The results indicate that perforation depth, perforation pore diameter, perforation density and reservoir thickness affect productivity. The deeper the perforation depth is the larger is the pore diameter, the more is the perforation density, and the larger is the produc- tivity ratio. Also the hydraulic jet perforation technology is more suitable for the thin oil reservoir than the thick oil reservoir. The bottom water coning can be controlled effectively by implementing this technique thereby playing an important part in enhanced oil recovery.
