摘要
阐述了河南稠油油藏“浅、薄、稠、散”等基本特点,指出常规蒸汽驱无法成功地开采这样的油藏。水平压裂辅助蒸汽驱不但可以变蒸汽超覆盖这个不利因素为有利因素,而且极大地降低了蒸汽驱全系统的热损失,从而提高了蒸汽驱全系统的热效率。在国外,该方法成功地开采了超稠油油藏和浅薄层稠油油藏。综合研究表明采用水平压裂辅助蒸汽驱开采河南稠油油藏是可行的。
This paper expounds that the characteristics of viscous Oil reseavoirs in Henan Oil Field is shallow, thin.Viscous and scattered. Points that conventional steam drive con't produce with success these reservoirs. But the horizontal Fracturing auxilary steam drive not only can turn unfavourable factors of steam onlap into favourable ones, but also reduce greatly heat loss of the steam drive. Comprehensive researches show the new production method to be feasible in Henan Oil Field.
