Research On Well Production Logging Technology In Horizontal Well

Since the "Eleventh Five-Year" for the realization of sustainable development of domestic oil and gas production,the "three lows" reservoirs,deep natural gas developing technology,mining technology,horizontal wells have been large-scale used.For heavy oil reservoirs,high-inclination multi-layered reservoirs,naturally fractured reservoirs,thin reservoir with gas cap,and the exploitation of bottom water reservoir and offshore fields,horizontal well technology has its unique advantages.Therefore,the dynamic monitoring of horizontal wells is currently the most important issue that must be resolved.This paper analyzes and summarizes the existing transportation technology.A crawler is developed.The production technology of horizontal well production profile is also summarized.A pumping simulation technology is proposed.On this basis,the corresponding case study of horizontal well production process is made.Compared with conventional vertical wells,horizontal wells and reservoirs can increase the flow area,change the way near wellbore flow,and reduce flow resistance.So it can produce more oil in lower pressure gap.Production technology for horizontal wells research will improve oil and gas production capacity,extend the life of oil exploration.Development of new technologies of horizontal well production logging of reservoir monitoring is of great significance to solve the problem of horizontal wells management.
