PRACTICAL APPLICATION OF CONNECTION SURVEY AND DOWNHOLE WIRE SURVEY IN A METAL SHAFT

HUANG Zhong-de;Anhui Shanshui Surveying and Mapping Institute;  
With the development of surveying and mapping science and technology, total station has replaced traditional transit for angle measurement and steel ruler for edge measurement. However, downhole operation is affected and limited by environmental conditions, how to improve the measurement accuracy of conductors and obtain high-quality conductor measurement values are the focus to be paid attention to and discussed in the surveying and mapping process. Based on an engineering example, this paper introduces the method of two times of connection survey between the ground and downhole, and the process of total station measurement of traverse,some methods and techniques to improve the precision of downhole traverse survey and their applications.
