| 摘 要： | 利用水平井技术可有效控制底水油藏普遍存在的水锥问题，然而这一技术受油藏地质条件、操作参数等许多因素影响。本文以江苏油田永安25区块为例，详细研究了不同油藏参数、操作参数等对原油产量的影响。研究结果表明，水平井产量随水体倍数、油层厚度、平面渗透率的增加而不断增加；对于该地区，合适的避水高度为0.3h～0.4h；合适的采液速度为130m3/d；合理的提液时机在含水率达到50%～60%时。 |
| 关 键 词： | 底水油藏；水平井；避水高度；采液速度 |

| Abstract: | The water coning, which exists common in bottom water reservoir, can be controlled effectively by horizontal well technology, but it is effected by many parameters, such as reservoir characters, operating parameters. Taking Yongan 25 block in Jiangsu oilfield for example, the effects of reservoir parameters and operating parameters on oil production were studied in detail in this paper. The results show that the oil production increases with the increase of water volume, reservoir thickness and horizontal permeability. To this research area, the suitable height of water avoidance is 0.3h ~ 0.4h; the suitable liquid production rate is 130m3/d; the suitable liquid enhancing time is time while the water cut is 50% ~ 60%. |
| Keywords: | bottom water reservoir horizontal well height of water avoidance liquid production rate |
