海上油田水力压裂储层改造技术研究与应用

Research and Application of Hydraulic Fracturing Reservoir Reconstruction Technology in Offshore Oilfield

【目的】为了实现海上油田含油气储层的精细评价与改造,进一步提升海上油田勘探开发效益。【方法】开展基于海上油田水力压裂储层改造技术的研究与应用,通过只射开下部射孔段的方式,避免以往全部射开射孔段后进行水力压裂所带来的改造效果差且难以弥补的短板。【结果】实现了海上油田目标储层的精准评价,具有良好的增产效果。【结论】与传统压裂方法相比,水力压裂储层改造技术可以有效避免储层评价时所产生的地质与环境风险,具有极好的推广价值。

[Purposes]This paper aims to achieve precise evaluation and transformation of oil and gas bearing reservoirs in offshore oilfields,and further enhance the exploration and development benefits of offshore oilfields.[Methods]This paper carries out research and application of hydraulic fracturing reser-voir reconstruction technology based on offshore oilfields,and avoids the shortcomings caused by hydrau-lic fracturing after all the perforated sections being perforated,which are difficult to make up.[Findings]Accurate evaluation of target reservoirs in offshore oilfields was achieved,with good stimulation effects.[Conclusions]Compared with traditional fracturing methods,hydraulic fracturing reservoir reconstruc-tion technology can effectively avoid the geological and environmental risks generated during reservoir evaluation,and has excellent promotion value.
