低压边远零散井伴生气产量预测计算研究

Study on Prediction and Calculation of Associated Gas Production in Low-voltage and Remote Zero-dispersion Wells

针对油田边远零散井的产量和压力低、稳产时间短的特点,通过在解析生产井配产二项式模型基础上,构建简化生产动态曲线模型和产气量预测模型。根据某油田典型边远零散井生产参数条件开展实例应用,绘制了产能动态关系曲线,验证了其生产状态,并计算得到往后5年的产气量预测。研究分析结果可基本判断单井的生产变化,为油田实际生产提供一定的理论指导作用。

Aiming at the characteristics of low output and low pressure and stable production time of oilfield remote scattered wells,a simplified production dynamic curve model and gas production prediction model were constructed based on the analytical binomial model of production wells.According to the production parameters of typical remote scattered wells in a certain oilfield,the application of the production parameters was drawn,the production dynamics curve was drawn,the production status was verified,and the gas production forecast for the next 5 years was calculated.The research and analysis results can basically judge the production changes of single wells and provide a certain theoretical guidance for the actual production of oil fields.
