Analysis and Countermeasures of Casing Deformation Causes in Gangxi Oilfield;

The inhibitory functions of inorganic salts (KCI,NaCL and CaCl_2) ,single or inbinary mixture,to the stale samples taken from Dagang Oil Fields are studied bycapillary suction time (CST),dilatancy,and rolling tests.

Taking the Beidagang oil field as an example, this paper studies the practical way of inferring the present-day stress field of oil field by making an integrated analysis of the data of earthquake observation, bore hole breakouts and hydraulic fracturing.
