低渗透砂砾岩油藏合理采油速度研究

Study of Reasonable Production Rate in Low Permeability Glutenite Reservoir

合理采油速度的正确预测,对低渗透砂砾岩油藏开发规模、投资计划和矿场管理都十分重要,本文从油井产能角度利用油井流入动态曲线分析可能的最大产量点和从经济角度利用盈亏平衡分析两方面来确定合理采油速度。本文依据海拉尔油田贝301区块实际开发资料,最终得出该区块当油价为60美元以上时,采油速度在1.33%~1.36%之间为合理的采油速度区间。

Prediction of reasonable production rate is very important.It influences the development of low permeability reservoir and investment planning.The paper determines reasonable production rate between BEP in economy and IPR of oil well,and economic limit for well pattern density of oil field.On the basis of the data in Bei301 of Hailaer oil field,the paper calculates that the Oil Production Rate between 1.33% and 1.36% is reasonable for rhe development of oil block,when oil pice is mor than 60$.
