NUMERICAL SIMULATION STUDY AND DEVELOPMENT MEANING OF CHANG 1 RESERVOIR IN DING 31 WELL AREA OF YOUFANGZHUANG OIL FIELD IN ORDOS BASIN
油气藏数值模拟及其对开发的意义――以鄂尔多斯盆地油房庄油田定31井区长1油藏为例

Through fine geologic modeling of Chang 1 reservior of Ding 31 well area in Youfangzhuang oil field, numerical modeling is set on geologic reserve, oil production, watercut and pressure in the area. On this basis, residual oil distribution is researched, mainly on structurally high part, main channel deposits not flooded, oil sewed semidiameter of well and production well which is not perforation.To various distribution patterns of residual oil,3 methods are developed to production adjustment, including new adjustation well and sidetracking of old wells, perfection of injection-production pattern, production engineering potential development. The estimation of production index indicates that numerical modeling and production adjustment are effective.
