摘要:

通过物理模拟实验和数值模拟方法,研究了中原油田胡12块原油的氧化性能与氧化规律,确定了低温氧化动力学参数,评价了中、高渗透非均质油藏空气泡沫的封堵特性与调驱效果,优选了空气泡沫调驱的注采方案。矿场先导性试验结果表明,胡12块原油具有良好的氧化性能,在中、高渗透非均质油藏中,空气泡沫-空气-水交替注入效果较好。说明空气泡沫调驱提高采收率技术是安全可行的。

Abstract:

The oxidation characteristics and regularity of crude oil in Hu12 Block of Zhongyuan Oilfield were studied by using physical experiments and numerical simulation.The low-temperature oxidation kinetics parameters of crude oil were obtained by oxidation experiments,and the blockage characteristics and the effects of profile control using the air foam injection technology in the medium-high permeable heterogeneous reservoirs were also evaluated by physical experiments and numerical simulation.The injection schemes using the air foam profile control and displacement technology were optimized as well.A field pilot of the technology shows that crude oil in the Hu12 Block after profile control and oil displacement of air foam injection has good oxidation characteristics.The air foam alternating air and water injection scheme has good effect on enhancing oil recovery in the heterogeneous reservoirs.

Key words: Zhongyuan Oilfield, heterogeneous reservoir, air foam profile control and displacement technology, physical experiment, numerical simulation, field pilot
