方法 利用广义达西定律 ,结合原油流变特征 ,推导拟塑性原油产能方程。目的 寻求适合吐玉克拟塑性原油的产能方程 ,并分析影响油井产量的因素 ,提高其开发效果。结果 经 5口井测试资料对比表明 ,拟塑性原油产能方程适合于吐玉克稠油油田。结论 吐玉克原油属拟塑性流体 ,其在油层中的渗流不符合常规达西定律 ;产能方程为确定吐玉克油田单井产能 ,制定合理的开发技术政策奠定了基础。
Methods The generalized Darcy ’s law is used to deduce the rheological property of crude oil. Objective To find a suitable production capacity equation for Tuoyuqigou crude oil and to analyze the factors that affect the oil well yield and improve its development effect. Results The comparison of the test data of 5 wells shows that the equation of plastic oil yield capacity is suitable for the Tuoyu heavy oil field. CONCLUSION Turpentine crude oil is a plastic fluid and its seepage in the reservoir does not conform to the Darcy’s law. The productivity equation lays the foundation for determining the single-well productivity of the Tuyuk Oilfield and formulating a reasonable development and technical policy.
