The New Oil Proved Reserves In HuaZiping Hezhuang District Of XingZichuan Oilfield

HuaZiping Hezhuang district of XingZichuan Oilfield is located in central Shaanxi Slope, Ordos Basin. Change6is the major oil layers. Regional structure is monoclinic gentle west-dipping. Strata slope down7-10m per kilometer. The dip is about half a degree or so and the inner structure is simple. In this configuration, there is developed on the background compaction due to differences in lithology formed nose uplift. On the basis of the geological characteristics this paper use volumetric method conduct the oil and gas accumulation of the district. The results for the reservoir geological reserves is295.53×104t, dissolved gas geological reserves is16.10×108m3. Then use the experience obtained from the formula for the calculation of recoverable reserves of reservoir244.67×104t, dissolved gas recoverable reserves calculation is1.93×108m3. Finally,through a reserve evaluation, we conclude that the development and construction of the area economically viable, have a better effect.
