低渗油田注水开发特色技术研究与应用实践

iming at the characteristics of low permeability oil reservoirs such as low permeability, low abundance, and low single well production. In order to effectively supplement the formation energy, increase the production capacity of a single well, and reduce the natural decline rate. In the process practical application of development, a set of characteristic technologies suitable for water injection development of low permeability oil fields has been formed by exploring fine geological research, fine adjustment, fine supporting technology, and fine management mode. In the practical application of low permeability oil field development, it effectively increases the production of a single well, the water drive area, and effectively controls the natural decline rate and the comprehensive decline rate. At the same time, remarkable results have been achieved: the daily production of a single well has been increased from 1.03 t to 1.38 t, the daily average oil increase is 0.35 t, an increase of 34%, and the water drive area has been increased by 197.9 km2, an increase of 24.3%. The study of this technology provides a reference for the development of low permeability oilfield.
