Abstract: For the properties of heavy oils produced from Hong 003 Block in Hongshanzui Oilfield of Xinjiang and their gathering and transportation problems, common transportation technologies for heavy oils are contrasted, and considered the topographical features of this block, agathering method with water blending for this heavy oils is proposed. Taking crude oils T1 and TA of Hong 003 Block as a study subject, their basic properties, rheological and viscosity-temperature behaviors are tested and analyzed using crude oil water cut, rheological anddensity test methods, and the viscosity and drag reduction effects of oil-water flows for the two heavy oils are evaluated by using a flowtestloop. Results show that crude oils T1 and TA belong to typical general heavy oil and extra heavy oil respectively, their flowability can be improved by blending water with the heavy oils or other methods. The phase inversion points of water in oil emulsions are about 40 wt% and 45 wt%. When the water cuts of the two heavy oils blended with water are higher than 55 wt% and 60 wt%, all of the apparent viscosities of their oil-water flows are about 100 mPa·s under the temperature range of 60~70 ℃, presenting a significant viscosity reduction effect.Therefore, the Hong 003 heavy oils blended with water can be gathered successfully.
