Occurrence Law of Remaining Oil in Heavy Oil Reservoirs With Strong Edge and Bottom Water in Taiping Oilfield

doi:10.7657/XJPG20210207

Abstract

Abstract:

Reservoirs in the lower member of the Neogene Guantao formation in the Taiping oilfield have strong and active edge and bottom water, so that water invasion is severe, the reserves producing degree and the recovery percent of reserves are low and there is a large amount of remaining oil, which should be produced by adjusting the development pattern. According to the development pattern and the occurrence law of the remaining oil, infill horizontal wells were located to change the flow field, large water channels were plugged, and cold production and viscosity reduction technologies were applied to enhance the oil recovery. Finally, the oil production has been increased, and the development cost of the heavy oil has been reduced significantly. The supporting technology developed during producing the heavy oil reservoirs in the lower member of the Neogene Guantao formation in the Taiping oilfield can be a reference to developing similar heavy oil reservoirs with strong edge and bottom water.

Key words: Taiping oilfield, Guantao formation, heavy oil reservoir with edge and bottom water, microscopic pore structure, remaining oil occurrence law, flow field adjustment, cold production and viscosity reduction, enhanced oil recovery
