The Study On Combined Development Adjustment Of Baka Oil Field

Low permeability sandstone reservoir has become an important terrestrial reservoir types in oil field development. In recent years, efficiently developing low-permeability fractured reservoirs has became important and difficult in the oil industry. Baka oil field is early put into the development of the first ultra-low permeability fractured reservoir in the Turpan-Hami Basin. In the west of Shanshan arc belt, Baka oil field is a long axis of the anticline oil reservoir, fully water flooding in 1996, water flooding strata is Jurassic Xishanyao reservoir. In use of geological reserves of 7.1 million tons, the highest annual output of oil is upto 12.7 million tons in 1997, oil began to enter the high-speed decreasing from 1998, to improve the Baka oilfield water flooding effect, slow down natural decline, enhance the oil production rate and recovery. Then carry out geological characteristics of oil field and comprehensive adjustment Baka oil field, started in rebuilding underground system, Focus on structure, reservoir characteristics, sedimentary facies, geological model. The fracture system is the most important, geological cracks model is established. Carry on Baka oil reservoir simulation and Tapping Technology adaptability evaluation, quantify the remaining oil distribution, made targeted adjustments and recommendations about water cycle, single well stimulation, well transform, infill. Make a strong guiding significance to improve the effect of development of Baka oilfield and strong reference to improve the development reservoir of the same fractures.
