摘要:
在致密油藏中,何种提高采收率技术可以取得更好的效果尚不明确。针对此问题,文中建立了由2条半缝组成的注采单元,借此对注水与注气在驱替和吞吐2种开发方式下的提高采收率潜力进行了分析,并研究了基质渗透率、注采间距对最终采收率的影响。结果表明:由于气体的注入性较强,因此注气的开发效果优于注水;对于基质渗透率为1.00×10-3 um2的储层,气驱的采收率较高;对于基质渗透率为0.10×10-3 um2和0.01×10-3 um2的储层,吞吐的开发效果更好;在基质渗透率为0.10×10-3 um2的条件下,注采间距对吞吐的影响较大,随着注采间距的减小,采收率增加明显,但注采间距对驱替的影响则较小。研究结果为大庆油田外围致密油藏进一步的开发方式提供了选择和理论支持。同时,对于致密油藏开发效果较好的吞吐开发方式,在布井和压裂时应充分考虑注采间距对采收率的影响,合理施工,以将效益最大化。
Abstract:
It is still not clear which EOR techniques can get better effect in tight reservoir. To solve this problem, an injection-production unit consisting of two half-fractures is established to analyze the EOR potential of water and gas injection under the modes of displacement and huff and puff, and to study the effects of matrix permeability and injection-production spacing on the final recovery. The results show that the development effect of gas injection is better than water injection because gas has a higher injectivity. When the permeability is 1.00×10-3 um2, the recovery of gas flooding is higher; when the permeability is 0.10×10-3 um2 and 0.01×10-3 um2, more oil can be produced by huff and puff process. Under the condition of matrix permeability of 0.10×10-3 um2, the injection-production spacing has a great influence on the huff and puff process, and the recovery factor increases obviously with the decrease of the spacing, but the effect on displacement is small. The research results provide the choice and theoretical support for the further development of tight oil reservoirs in the periphery of Daqing. Meanwhile, for the huff and puff process, which have a better performance in tight oil reservoir development, the influence of different fracture spacing on oil recovery should be fully considered during well layout and fracturing, so as to maximize the benefits by reasonable operation.
