摘要
复杂结构井是以水平井、双水平井、连通井等为代表的一系列复杂定向井,是高效开发低渗透、非常规及海洋油气等复杂油气田的主要井型。在复杂结构井钻井作业中,普通钻井技术如MWD/LWD等,无法满足钻头精准定向的要求。磁导向钻井技术;可以实时调整正钻井钻头的位置参数,能够满足与目标井距离精确测控的技术要求。这种钻进方式在辽河油田SAGD双水平井钻井中已经得到有效应用,并在储气库老井重入作业中有广泛的应用前景。
Complex structure wells are a series of complex directional wells represented by horizontal wells,double horizontal wells and connected wells.They are the main well types for the efficient development of complex oil and gas fields such as low permeability,unconventional and offshore oil and gas.In the drilling operation of complex structure wells,ordinary drilling technologies such as MWD/LWD can not meet the requirements of accurate bit orientation.Magnetic steering drilling technology;can adjust the position parameters of the drilling bit in real time,and can meet the technical requirements of accurate measurement and control of the distance from the target wells.This drilling method has been effectively applied in SAGD double horizontal well drilling in Liaohe Oilfield,and has a wide application prospect in re-entry of old wells in gas storage.
