Abstract
The gas drilling can enhance the drilling rate greatly fast,favor the well deviation control.This paper summarized the newest research progress of gas drilling in China,including following several aspects:Considered each kind of influence of factor,revised the smallest gas injection rate;Strengthened the research on hole stabilization factor and the influence rule;Each kind of new technology used in well logging of the gas drilling,improved the well logging effect;The development and application of the air hammaer will be the development direction of gas drilling;The analysis of drilling rig(column)'s failure reasons and mechanism have provided the theory basis for the preventing and controlling measure.In addition,the paper has also carried on the forecast to the research direction of gas drilling in the future.
