摘要
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。
Method\ Incorporating rheology characteristics of crude oil and using general Darcy principle, productivity equation of analog plastic oil is deducted. Purpose\ To find out productivity equation suitable for analog plastic oil in Tuyuke oil field, analyze factors affecting well production and enhance development results. Result\ Test results comparison of 5 wells show that the described productivity equation for analog plastic oil is suitable for applying in the whole Tuyuke heavy oil field. Conclusion\ Tuyuke oil belongs to analog plastic fluids and its percolation in oil bearing zones doesn't conform to conventional Darcy principle. The appearance of this productivity equation sets a firm foundation towards detemining single well production and working out reasonable development technology and policy.
