A Research Of Drilling And Completion Technique About Changyuan Near Fault In Daqing

In the past development and application of oil field,in order to pursue the reservoir thickness controlled by a single well and to avoid the complex construction in drilling engineering,there are fewer wells in the vicinity of the fault,in which one is Daqing Changyuan.So with the developed faults,in Daqing Changyuan the relationship between injection and production is not perfect resulting in the rich oil remaining.At present,the Daqing Oilfield has entered the stage of extra-high water development,this kind of oil area near the fault zone will be an important area for the oil field to continue to develop.Considering the structure of fault area and the remaining oil distribution,the research on its development means need to be deepened.In this paper,the remaining oil in the vicinity of Daqing Changyuan faults is screened and its distribution is clearly understood.A series of technical problems obstructing the safe and efficient drilling construction of wells near the faults are solved,such as the borehole stability,well trajectory controlling,coring operation and well completion.Accordingly,a complete drilling and completion technology to efficiently develop the remaining oil in the fault area is proposed.It is of great significance to improve the recovery of oil production and the high yield of Daqing oilfield.
