The Follow-up Assessment Of effect of Pilot Test of Steam Flooding in Jin 45 Block

摘要

The steam flooding pilot test in Jin 45 block has steam flooding 4 years since June 2008 turned the drive. But now, it still don't understand the production dynamic, the degree of use of the reservoir, the effect of development of this pilot and the situation of temperature field, pressure field and saturation distribution field. Now petrel and CMG software are applied for the tracking simulation, on the basis of optimization of injection-production parameters, put forward effective adjustment scheme for the forecast of steam flooding. The results show that: at present, test is in displacing stage, after two adjusted in 2010 and 2011, the daily fluid and daily oil increased, moisture content decreased. The using of the layer of I35 is obvious. The using of the 1, 2 small layers of I group is high, the 4 small layer is low, the using of plane is great different. The pilot test of steam flooding in Jin 45 block has achieved good development effect, it offers an important basis for determining to replace mining mode of the later stage of cyclic steam stimulation of reservoir.
