优快钻井技术是中原油田近几年发展起来的新技术，在钻井提速、效益提升方面效果明显。井位优选技术是优快钻井技术的重要内容之一，是优质快速打好井的前提。定井位过程中，方位及靶前位移是确定井口位置的关键。靶前位移的确定要考虑全井的轨迹控制方式，最大井斜影响具体控制方式。通过优选井位，提高了钻井速度。

Excellent fast drilling technology is a new technology developed by Zhongyuan Oilfield in recent years, and has got obvious results in drilling speed and economic benefit. Well location optimization technology is one of the important contents in this technique, and is the essential prerequisite. Orientation and pre-target displacement are the keys in well placement process. The control mode of whole well trajectory must be considered in determining pre -target displacement, which is also affected by maximum well deviation. Through the optimization of well location, drilling speed can be improved.
