The Production Technical Research Of Heavy Oil Reservoir In The Thin Bed

The heavy oil in the thin bed of Binnan oil production factory mainlydistributes in Guantao formation of Shan 2 block in Shanjiasi oilfield andSha 1 interval of Wangzhuang oilfield, and is in the select criterion lowerlimit of steam stimulation for heavy oil reservoir. The oil area of Sha 1interval ofWangzhuangoilfieldis 25.8km2.Theblockis heavyoil reservoirwhichisformationsensitivityandsevereheterogeneity.The research is in view of Sha 1 interval of Wangzhuang oilfield. Bymeans of numerical simulation, the heat transfer performance of heavy oilreservoirinthe thinbedis researched. Accordingtoreservoir feature, steamchanneling in steam soak is analysed and the pattern of steam driveparameter is researched in view of heavy oil reservoir feature inWangzhuang oilfield, for example, thin reservoir, multi-interbededformation, larger and unknown heat loss during steam soak, mainparameters which are not simulated and optimized. The intensity, drynessfraction and velocity of steam injection are researched and optimized. Thenthe development effect of heavy oil reservoir in the thin bed is advanced.The technique of active water injection is researched and feasible programis given. The research offers foundation and technique support for later development,andalsohassenseoftheoryandpractice.
