SOME DIFFICULT PROBLEMS IN THE DEVELOPMENT OF SURFACE OIL AND GAS GEOCHEMICAL EXPLORATION TECHNIQUE AND THE COUNTERMEASURES

The surface oil and gas geochemical exploration technique has made remarkable application results.Nevertheless,Due to the different standards for success rate calculation and the inherent defects of the technique,people do not have much confidence in this technique.Therefore,the development of surface oil and gas geochemical exploration technique should be on the one hand based on reliable experimental data,rigorous mathematical deduction and theoretical modeling and on the other hand combined with geological,remote sensing and non-seismic geophysical methods so as to give full play to its advantages such as rapidness,low cost and directness.
