Research Of The Friction Reduction Technology Of The Large Displacement Wells In Xinggu 7 Area Of Liaohe Oil Area

The drilling technology of the large displacement wells is a new comprehensive drilling technology developed rapidly in recent years.It can be widely used in exploration and development of oil and gas reservoirs in offshore oil fields,offshore oil fields,and complex geological conditions.The utilization of the large displacement wells drilling technology can greatly reduce the investment cost of oil exploration and development,at the same time it can increase the output of single well.During the construction of the large displacement wells in Xinggu 7 area of Liaohe oil area,the phenomenon of larger friction occurred,which affected the efficiency of construction.It is necessary to carry out the research on the friction reduction technology for the large displacement wells in this area..In this paper,,the development and application of large displacement well drilling technology is introduced,and the problems encountered in the construction process of large displacement well in Xinggu 7district of Liaohe oil area are discussed.From the view of drilling string optimization design,trajectory control technology,drilling fluid performance,drilling parameter optimization,cementing string structure,downhole tools and so on,discussing the underground problems occurring during the drilling process of Xinggu 7 district.The pertinent technical measures are formulated to solve the field problems and achieve the purpose of improving the speed of drilling in this district..In this paper,the construction difficulties of Xinggu 7 district are analyzed and studied.According to the geological conditions in this area,the pertinent technical measures are made to the problems existing in the construction from many angles.It has a positive significant reference to the application of the drilling technology of the large displacement well in the 7 district of Xinggu.
