Abstract:

Residual oil distribution study is the basis of subsequent rolling development of oilfield, and the accuracy of numerical simulation is the key for the analysis of residual oil distribution rule. Longhupao Oilfield is low permeability reservoirs controlled by lithology and structure, belonging to coastal shallow-lake facies and delta front deposition. Aimed at the geology, structure and sedimentary characteristics of Longhupao Oilfield, the reserves was fitted with virtual wells technology, PETREL-RE technology, segmentation and integration technology, partition fitting technology, endpoint calibration in stages and phase spreads. The fitting precision reached 91.6%, and the block geological reserves fitted precision error is lower than 5%. The residual distribution rule in planeand vertical was obtained, which can guide the further development of oilfield.
