The Status and Dominant Factors of Oil Remained Distribution in XiaErMen Oil Field

XiaErMen oil field is a representative fault oil field. Remained oil distribution is very complex in virtue of long-term quick exploitation. This article not only summarizes the collective character of remained oil distribution and the relation with sediment facies, but also concludes dominant factors that effect remained oil distributing in H3 segment from three aspects: sediment models, geology and wells network,which are applied to deploy and optimize wells network.
