摘要 在钻井过程中,随钻计算地层温度对快速、安全钻井和地质勘探具有极其重要的意义。由于钻井施工过程的特点,施工作业过程中难以用井下测量工具对井内温度进行实时连续测量,因此利用录井测量的入口温度和出口温度等数据建立了实时计算地层温度的数学模型,编制了用于钻井过程的录井施工的相应软件,实现了录井过程的地层温度实时计算并取得了现场计算数据。 In the process of drilling, calculation of formation temperature while drilling has significance for rapid and safe drilling and geological exploration. Because of the characteristics of drilling operation process, it is difficult to perform a real time continuous measurement of the temperature in the wells using downhole measurement tools. This paper constructs a mathematical model for real time calculation of formation temperature using import and export temperature measured by logging, works out corresponding software which can be used in the logging operation in drilling process, realizes real time calculation of formation temperature in logging process, and obtains calculated field data.
