【Abstract】 This paper analyzes the horizon velocity parameters based on the well logging constrained inversion technique through using the STRATA inversion to study the change laws of average horizon velocity,abnormal pressure,and fluid potential in upper K1c2 formation. On this basis,the abnormal pressure and fluid potential are calculated in the area and the reservoir pressure and fluid potential are computed in terms of the extracting of horizon velocity of K1c2 formation in the area. The plane distribution of reservoir pressure and fluid potential has been obtained for this set of strata. The flow direction of fluid,i.e. hydrocarbon migration direction,has been understood within the sag according to the plane diagram of reservoir pressure and the plane diagram of fluid potential,which provides a definite target for further petroleum exploration.更多还原
