PRODUCT DETAILS

           ER-E1 Gyroscope for Downhole Survey


ER-E1 is with small size and strong shock resistance. It can be used for the system which with small space, was widely used in borehole gyro survey tools and well logging tools.  It is designed for dynamical orientation and positioning in the drilling field.

                                                               ER-E2 Gyroscope for dynamic well logging


ER-E2 is specially designed for borehole drilling field which has overcame the following technical difficulties, especially its operating temperature up to 100 degree centigrade. Inertial devices are more adaptable and better applied in the drilling field than they are in aviation field due to its ability of working in poor conditions. The life of DTG and its adaptation in temperature are specified, especially when it was used in higher temperature.
