| According to the reservoir of Daqing oil nine plants in Gulong area of shallow,thin oil reservoir,located in more arable land,the slant well drilling technology development efficiency low,carried out the research of drilling horizontal well Gulong area technology.The main purpose is for the characteristics of Gulong area formed a mature horizontal drilling technology.The main content of research includes according to the geological characteristics of Gulong area design and optimize the structure of well depth,BHA optimization design,well trajectory optimization design and optimization of downhole tools,guide trajectory prediction technology.With the deepening of oilfield development in Gulong area,Gulong-Ping 1,Gulong-Ping 2 and Gulong-Ping 3 well drilling success,drilling of horizontal well Gulong technology will be widely applied to provide guarantee for the reasonable layout and adjustment of well enhanced oil recovery enhancement,but also to make the major contribution of the nine production plant oil production,providing strong technical support for the sustainable development of Daqing oilfield.Finally,through the laboratory research and field test,the BHA,downhole guide tool and wireless measuring instrument are optimized,the screw drill is selected,and the purpose layer is accurately judged by trajectory prediction technology to ensure precise Hit.The formation of a set of drilling technology suitable for the Grape in the Cologne area of Daqing,to improve the penetration rate,and improve the drilling ratio in the horizontal section.At the same time,it is also found that the length of the horizontal segment affects the penetration rate of the there,the traditional down-hole building angle tool is difficult to reach the horizontal footage of the most advanced rotary guide drilling tool. |
