针对滨江油田海域0~2m水深内的滩涂地区,地下油气藏资源丰富,构造简单,但储集层为低孔、低渗-特低渗型,开采难度大的问题.通过地质和储层研究,依据它的油藏分布特征和油藏类型,编制渤海湾盆地黄骅坳陷滨江油田开发利用方案.方案制定了开发原则和开发方式,部署直井、定向井、大斜度井和水平井等,为提高采收率和采油速度,制定了合理的井网密度,方案实施后可累计采油xxx×104t,方案税后财务内部收益率达到并超过了行业基准值,经济效益较好.%Binjiang oil field is under the tidal flat area where sea water depth ranges from 0 to 2 meters,and its structure is simple,but the reservoir is of lower porosity,lower permeability and ultra low permeability,which increases the oil-extracting difficulty.Through geologi-cal and reservoir research,the development and utilization scheme of Binjiang oilfield in Huanghua depression of Bohai Bay Basin is pre-pared according to the reservoir distribution characteristics and reservoir type.The detailed development principles and development methods are included in the scheme.In order to improve the oil rate and final oil recovery,we deploy vertical well,directional well,Highly deviat-ed well and horizontal well to make well pattern density more reasonable.After the implementation of the program,cumulative oil recovery will be up to 99.87 × 104 t,and financial internal rate of return after tax will achieve and exceed the industry reference value.
