Failure Analysis and Preventive Measure of Drilling Tool in Gas Drilling

Xiaoying Liu, Cnpc Ocean

Abstract

Aiming at failure of drilling tool in gas drilling,searching the field situation of gas drilling was carried and surveyed,specifically at northeastern Sichuan gas field and TABNAK gas field were directed.The site condition data using relevant theory and field experience was analyzed and the main characteristics and causes of the drilling tool failure in air drilling were found out.The reasonable proposal of how to avoid drilling tool failure in air drilling was put forward,the scientific basis for decreasing or preventing drilling tool failure in air drilling was proposed.
