Abstract

Abstract

On the basis of the geological study of hydrocarbon migrating and accumulating into reservoir in Guantao Fm., Zhanhua depression, this experiment models the influence of opening fault on petroleum migration and accumulation in the formation with a 2-D model. The results are as follows: (1) The moving pattern and phase of fluids in fault zone have great influence on moving path and pattern of petroleum in Guantao Fm.. When continuously injected, petroleum could have occupied the fault zone firstly, then moved laterally down the top of its upper formation, and finally down the top of its lower formation. However, in impulsive (unsteady) injection, petroleum occupied lower part of fault and the lower Guantao Fm., firstly, then upper part of fault, and migrates laterally in the lower Guantao Fm.. Finally, the upper Guantao Fm. moved laterally. In addition, when petroleum and water injected together, they would separate because of hydrodynamics. (2) When injected continuously (steadily), petroleum migrated laterally in sand bed above the barrier, while in impulsive (unsteady) injection, it migrated in both upper and lower Guantao Fm., in which quantity of lateral migration in lower sand bed is bigger than that in the upper sand bed when petroleum is injected only, and the quantity of lateral migration in upper sand bed is slightly bigger than that in lower sand bed when petroleum and water are injected together. (3) Continuous (steady) injection is favorable for petroleum accumulation in upper Guantao Fm., sand bed, while impulsive (unsteady) injection is favorable for petroleum accumulation in lower Guantao Fm., sand bed. In addition, petroleum is apt to accumulate in upper of Guantao Fm., when it is injected together with water because of hydrodynamics.
