- The saltier the water, the higher the pressure it takes (and hence the more energy you need) to push water through a membrane in order to leave behind the salt. 后面又说水越咸,所需的压力越大,用的能量越多。这不又是与水源的咸度有关了吗?
- Bottom water coning is an important factor affecting reservoir development effect, causing earlier water breakthrough, rapid water cut increase and production decrease. 摘要底水锥进是影响底水油藏开发效果的重要因素。
- When horizontal section is short, the water coning is formed in a short time, the two shoulders of the coning are steep and the oil/water interface deforms greatly. 采用水平井开发时,由于水平段较长,油藏内井筒附近生产压差较小,底水形成水脊,水脊脊进速度慢,见水时间推迟,提高了无水期产油量。
- The formation and development of water coning were visualized, and the effect of water coning on water breakthrough times and recovery ratios was studied. 采用直井开发时,井筒附近油藏有较大的压力降,底水形成水锥迅速突破井筒,油井在较短时间内见水。
- In process of natural mining of bottom water, bottom water coning is caused by some factors such as oil-water contact without interlayer, bigger mobility, and so on. 底水油藏在自然开采过程中因油水界面无隔层、流度比较大等,易造成底水锥进,有效控制底水锥进速度直接影响油藏采出程度,为此,进行了先期堵水技术研究。
- In consideration of the characteristics of Fault Block CH3, a study is conducted on numerical model of bottom water coning and reservoir numerical simulation. 根据CH3断块的油藏特征,对底水锥进数值模型及油藏数值模拟进行了研究。
- The source function of the partially-penetrated well in the center of a reservoir with water coning is consistent with the source function of the partial penetration at an early time. 具有井筒效应的源函数(随时间变化)之特性是在开始时为水平直线,井筒效应结束后,会与一般的无限表面圆柱源函数或无限线源函数相同。
- Sidetracking horizontal wells were used successfully to control the water coning occurred in Hongnan oil field, hence the development and the economy benefits of the block were improved. 红南边底水油田在开采过程中出现了锥进问题,通过应用侧钻水平井新技术治理底水锥进获得了成功,提高了区块开发效果,获得了较好经济效益,为同类油藏的开发提供了可借鉴经验。
