The Research of Water Influx Law for Edge-Bottom Water Heavy Oil Reservoir

Wenjia REN

Abstract


The Liaohe Jin 91 block has entered the late period of steam huff and puff, the entire block is seriously water invaded. At this stage the water invasion regularity for edge-bottom water of heavy oil reservoir is not clear. In Jin 91 block two well group, for example, we model the fine geological with petrel soflware, application the CMG software throughput of history matching, and combined with homogeneous core model water influx the indoor physical model experiment,to research the water influx regulation of the edge-bottom water heavy oil reservoir. The results show that the water invasion form is given priority to with bottom water coning, the Edge water tonguing is secondary, and in accordance with the experimental data at the same time, fitting out the exponential function relationship of water influx with the differential pressure and temperature, which provides a theoretical basis for promoting the development of edge-bottom water steam flooding of heavy oil reservoir.
