大位移井钻井技术是当今定向井、水平井技术的综合系统工程,可广泛地应用于滩海油田、海上油田和地面条件极其复杂的油气藏的勘探开发。它是在定向井、水平井和深井钻井技术的基础上发展起来的一种新型钻井技术。包括管柱的摩阻和扭矩、井眼轨道设计、井壁稳定、大位移井钻井液的应用等一些关键技术。大位移井是随着相应的科学技术和其它钻井技术的发展而发展,其技术的应用在复杂区域的开发中节省投资,提高效益。
Large displacement well drilling technology is a comprehensive systematic engineering of directional well and horizontal well technology. It can be widely used in the exploration and development of the beach oil field, offshore oil field and the oil and gas reservoir with extremely complicated ground conditions. It is a new type of drilling technology developed on the basis of directional well, horizontal well and deep well drilling technology. Including the friction and torque of the string, wellbore orbit design, wellbore stability, the application of drilling fluid drilling fluid and some other key technologies. Large displacement wells are developed with the development of corresponding science and technology and other drilling technologies. Their application of technology can save investment and improve efficiency in the development of complex regions.
