BITUMEN EXTRACTION TECHNOLOGY FROM BITUMINOUS SAND DEPOSITS

English abstract

Today considerable experience in the development of tar sands is accumulated. However, well-known mining technologies do not cover the entire depth range of natural bitumen deposits. In addition, there are significant energy-intensive technol-ogies and negative environmental impacts. In view of this, the purpose of this work is to improve the method of extracting natural bitumen in site for a deposit interval of 75-200 m and to substantiate the basic technological scheme of this method. The proposed method of extracting bitumen from poorly cemented reservoirs in the depth range of 50 – 400 m provides: creation of artificial production; the transfer of the rock into the water mixture composition under the action of high pressure jets of a heated mixture of water, a hydrocarbon solvent and a flotation agent; separation from the rock and concentration of bitumen in the production as a result of its heat-ing, dissolution and flotation; selection of depleted bitum slurry from the production by gas lift. The proposed method of extracting bitumen is the transfer of the rock at the its occurrence site to the suspension condition on the excavation created by the hydraulic production method, separation and concentration of bitumen by dis-solving it with a heated hydrocarbon solvent and a flotation agent (hydrocarbon reagents) and extraction in composition of the depleted rock slurry to the surface by the gas lift method. As the preliminary calculations show, the proposed method will allow the efficient extraction of bitumen and highly viscous oil from weakly cemented reservoirs in the depth range of 50-400 m. Also, the proposed technology creates the preconditions for the development of oil sands at a depth of 75-200 m since there is currently no effective technology for the interval. In addition, it can significantly reduce energy costs, environmental pollution and greenhouse gas emis-sions.
