摘要
国内不少油田引进了阿特拉斯公司1016型地层倾角测井仪,而具有类似功能的斯仓贝谢公司SHDT仪器也曾在我国部分油田服务。这些新型的倾角测井仪器较之各自的前代型号在功能及测量精度等方面有较大改善,特别是由于应用了新的测斜系统——三维加速度计和三维磁力计,从而提高了方位、倾斜数据的计算精度,增加了对倾角测井对比曲线进行速度校正的手段。本文阐述了新测斜系统的方位和倾斜数据计算方法,并讨论了利用加速度计测量数据进行速度校正的方法,以及将该速度校正方法推广应用于其他测井的可能性。
The diplog tool (1016 type) has been imported recently and put into application in many oilfields. The SHDT(Schlumberger)which has, more or less, similar characteristics and functions, is in wide use over our country. Compared with the earlier types, these tools are improved in data acquisition and measurement accuracy. A new inclinometer system of three-dimensional accelerometer and three-vector magnetometer ensures a high accuracy of orientation measurement and implementation of speed correction for correlation curves. This paper provides an overview of the inclinometer section and orientation data computation method for modern diplog instruments. The speed correction and the error analysis is discussed in this paper. Finally. the applicability of the speed correction method and three-D or one-D accelerometer to other logging tools is analysed.
