摘要
我国低渗透油气资源分布具有含油气多、油气藏类型多、分布区域广以及"上气下油、海相含气为主、陆相油气兼有"的特点,在已探明的储量中,低渗透油藏储量的比例很高,约占全国储量的2/3以上,开发潜力巨大。低渗透油藏由于自身特殊的储层特性,即油层储层渗透率低、丰度低、单井产能低,在生产的不同阶段需要采取相应的增产增注措施来保证油藏的开发效率以及油井的产量。相当于高渗透油田的开发来说,低渗透更容易堵塞,增大了低渗透油田的开发难度。为了最大限度的开发油田的潜能,获得更高的油气产能,提高油田的采收效率,在油田开发中不断研究增产增注的工艺技术,并在油田中不断的推广应用。
the distribution of low-permeability oil and gas resources in China has the characteristics of many oil and gas,many types of oil and gas reservoirs,wide distribution area and"oil and gas in upper gas and lower oil,marine oil and gas,continental oil and gas".Among the proven reserves,the proportion of low-permeability reservoir reserves is very high,accounting for more than 2/3 of the national reserves,with great development potential.Due to the special reservoir characteristics of low permeability reservoir,such as low permeability,low abundance and low single well productivity,corresponding stimulation and injection increase measures should be taken at different stages of production to ensure the development efficiency of the reservoir and the production of the oil well.As for the development of high permeability oil field,low permeability is easier to block,which increases the development difficulty of low permeability oil field.In order to maximize the potential of oil field development,obtain higher oil and gas production capacity,improve the recovery efficiency of oil field,continue to study the technology of increasing production and injection in oil field development,and continue to promote application in oil field.
