Present Situations and Proposals on Thermal Recovery Technology of Heavy Crude Oil in Bamianhe Oilfield

The thermal recovery technology aiming at the thin interbedded,thin bed and extremely thin bed heavy oil reservoirs has been developed gradually in the process of Bamianhe Oilfield development.Taking optimization of steam injection parameters and selection of well and horizon for steam injection as a core in order to guarantee steam injection quality,and taking forming a complete system of the forced sand control and oil layer prevention technologies as assisting measures make the huff and puff recovery technology become dominant in improving development effect for the heavy oil reservoirs mentioned above,which resolves the difficulties in recovering heavy oil reservoirs in Bamianhe Oilfield.
