Abstract:we analyse both the present situation and development tendency of micromagnetiztion hydrocarbon exploration,and summarize formation mechanism of micromagnetic anomaly. There are many factors causing micromagnetic anomaly,for in- stance,magnetic minerals produced in hydrocarbon seepage environment,elastic magnetite in rock beds,burnt dregs due to igneous metamorphism of sedimentary rocks,and other disturbance factors. The generation and distribution of the micro-magnetization have three uncertainties,namely,the intrinsic uncertainty in hydrocarbon seepage environment,the uncertainty due to migratory effect of underground water,and the uncertainty of chemical exploration. Thus,we must obey some definite rules in micromagnetization research. In addition,the micromagneti zation exploration should be grouped in non-seismic oil exploration methods,and combine with other methods to improve its accuracy.
