摘要
在进行油井清蜡时,现场技术人员通常是凭借经验确定空心抽油杆油井的热洗井温度,存在弊端。依据现场30井次实际热洗井数据,用最小二乘数法拟合,建立空心抽油杆油井的热洗井温度计算模型。通过相关系数R检验、回归系数的显著性t检验、回归模型的显著性F检验,证明了该模型中的温度变量X和Y之间的线性关系合理。现场应用数百井次,热洗井施工成功率100%。具有推广应用价值。
Determination of thermal washing temperature of hollow sucker rod by experience was uncertain.The least square method was used to fit the data of 30 wells in real time,and the mathematical model of heat wash temperature of hollow sucker rod was established.According to the correlation coefficient Rtest,significance t test of regression coefficients,significance Ftest of regression model,it is proved that the linear relationship between X and Y was reasonable.Hundreds of wells hot washing showed that the success rate reached 100%.The results of the study can be used for reference in other oilfields.
