摘要
采用丛式井开发低渗透油气田可以降低钻井成本和提高油气井产量,防碰绕障技术是丛式井钻井成败的关键。介绍了丛式井防碰扫描的原理方法、扫描参数的计算以及具体应用,可以利用该方法对各井眼的空间关系及钻头运动趋势作出预测,从而避免因各种原因导致的井眼相碰,具有重要的现实意义。
The cluster well drilling, as one of the most effective way of reducing drilling cost and improving output, has been used in low permeable oilfield, the well path and detouring techniques is the key point of cluster well drilling. In this article , theory , scanning parameter and application of anti - collision scanning method for cluster well were introduced. By this method, spatial relationships of each wellholes and movement trend of the drill bit can be predicted to prevent from wellbore striking.
