在兴隆台潜山带亿吨级新增探明储量申报过程中,从石油地质储量到可采储量计算的关键是要合理、准确地确定采收率,它是衡量油田开发效果和开发水平的重要指标。由于油藏处在开发初期,受资料所限,采收率只能应用经验公式法、经验取值法、类比法和数值模拟法求取。取值合理与否的关键是明确影响采收率的主控因素。通过分析,明确了影响变质岩潜山油藏采收率的主控因素包括储集岩岩石类型、储层物性、油藏驱动类型、油藏类型和地层原油粘度等。通过类比主控参数,确定类比油藏为边台潜山,相对准确地确定了兴隆台潜山带石油技术可采储量,为亿吨级探明储量的申报奠定了基础。
In Xinglongtai buried hill with 100 million tons of new proved reserves declaration process, from the oil geological reserves to recoverable reserves calculation is the key to a reasonable and accurate recovery, it is a measure of oil development and development level Important indicators. As the reservoir is in the early stage of development, limited by the data, the recovery rate can only be calculated by empirical formula, empirical value method, analogy method and numerical simulation method. The key to reasonable value or not is to clearly affect the main factor of recovery. Through analysis, the main controlling factors that affect the recovery ratio of the metamorphic buried hill reservoir are the reservoir rock type, reservoir physical property, reservoir driving type, reservoir type and formation crude oil viscosity. By analogy controlling parameters, it is confirmed that analogous oil reservoirs are hillside hillsides, and the recoverable reserves of petroleum technology in Xinglongtai buried hill area are relatively accurately determined, which lays the foundation for the declaration of proved reserves of 100 million tons.
