  • Descrição: In recent years, horizontal well development technology has gradually become one of the main technologies for the development of low-permeability reservoirs. Due to imperfect injection and production wells caused by environmental protection restrictions in water source protection areas, forest areas, and the impact of high water cut in horizontal wells, the Jiyun oilfield is dense. The energy in the formation of the oil block is insufficient, and the production of horizontal wells decreases rapidly. Since 2014, it has carried out generalized injection testing and achieved certain results. However, the results of the general absorption profile test showed that the water absorption was not uniform in each section and the section profile was inconsistent. In order to further improve the throughput effect and solve the water-absorbing contradiction in the general throughput profile, the digital distribution of the latest research results is extended to the horizontal wells, and an intelligent water distribution device and related tools for integrated vortex flowmeters are developed for horizontal wells. Tackling the formation of horizontal wells intelligent segmented waterflooding technology, realizing the automatic detection of subsection flow and real-time storage of production parameters for the 3 wells of horizontal wells, and cumulatively implementing 7 wells, increasing the oil by 2.1 t per well, to improve the development of tight oil in the oilfield and the improvement of the output of a single well provide effective technical means and has broad prospects for popularization and application.
