This work examines the operational parameters that may influence the performance of toe-to-heel steamflooding in a laboratory-scale simulation model built on the basis of the fluid and rock samples from a fractured, low-permeable, carbonate heavy oil reservoir in Southwestern Iran, called KEM (Kuh-e-Mond). Using vertical (V) or horizontal (H) injectors (I) and producers (P), the effects of different well configurations including VIVP, VIHP, 2VIHP, VI2HP, HIHP, and HI2HP, injectors’ traversal distance, producers’ traversal distance, and horizontal producer length have been investigated. In summary, the results show that 2VIHP scheme performs best in terms of oil recovery and areal/volumetric sweep efficiency. Also, traversal distance of the vertical injectors and horizontal producer length should be optimized to have the maximum performance. 相似文献

间歇注汽法—提高蒸汽驱效果的重要方法 总被引:5,自引:0,他引:5
蒸汽突破后,采用间歇注汽方式,可以达到抑制汽窜,提高蒸汽比容、波及体积、干度,油相相对渗透率,热利用率及自渗吸驱油之目的,从而提高稠油蒸汽驱开采效果.河南井楼油田零区试验区采用间歇注汽法取得了显著的效果.现场试验及数模研究结果表明,对薄层稠油油藏来说,合理的间歇注汽方式是每注30天,停30天,间歇注汽阶段合理的注汽速度应为连续注汽速度的1.5倍;对大型蒸汽驱开发单元来说,同一排注汽井为一注汽单元,相邻两排注气井的注汽时间应重复50%. 相似文献
