Changbei project is a cooperation project between Petrochina and Shell （China） company. For improving efficiency of development and shorten process of gas production. It begins from 2005 up to develop. In technique and technology aspect of drilling well, applied the extended reach dual-lateral horizontal drilling technologies. According to the request of drilling, carried out research including optimization of wellbore scheme, drilling mud, bit selection and bottom hole assembly etc. Come into being eight major specific drilling technologies. It is proved that the drilling technologies can improve efficiency of gas well development, speed of gas production and shorten drilling days.
