| Abstract: | This paper presents instable problem of igneous formation,analyzes such project coefficient as geology factors,mechanics,physical chemical factor of drilling fluid,and drilling string vibration which affect the destabilization of igneous rock.And then it proposes that rock mechanic theory in conjunction with drilling fluid chemical property as a combination to estimate the effect of drilling fluid on collapse pressure,develops further analysis on the erratic factors of igneous rock formation. |
