Abstract:

It's inevitable result of bending of geological drilling and will affect drilling quality.Therefore,in the process of drilling operation、collection、statistics data and analysed connected data,summarize regulations of drilling bending.At the same time,we should analyse and research the causes of drilling bending and take oppropriate measures to prevent and cont rol it,so as to improve the quality of drilling.

Key words: Geological drilling, Measurement of drilling bending, Ways of rectify a deviation, Prevention and control
