Abstract
With the increasing demand of oil, gas and mineral exploration and development and the development of logging technology, when drilling two or more wells, people need to carry out accurate measurement and positioning. a magnetic distance measurement system diagram for drilling multiple wells simultaneously. This paper presents a magnetic distance measuring system for drilling multiple vertical wells simultaneously. According to the magnetic field data, the geometric relationship between the two BHAS is determined, and the distance and orientation between wells are automatically located to maintain a predetermined geometric relationship, and then simultaneous drilling is realized. The algorithm is simple, the error is within the acceptable range, and it can further improve the efficiency of drilling operation, save time and reduce cost.
