孤岛油田中一区馆下段油藏数值模拟研究

Reservoir numerical simulation research on the Guanxia member of Zhongyi area, Gudao oilfield.

针对孤岛油田中一区馆下段地质、生产情况，建立了适合该油藏的地质模型，并应用数值模拟技术研究了油藏的水体及其对生产的影响情况，搞清了剩余油分布状况，制定了加密调整方案并进行指标预测。方案在现场实施后，新井平均单井日产油１０．２ｔ／ｄ，含水７１．８％ ，已累积增油１２４１５ｔ，改善了油田开发效果，也给同类油藏开发提供了方向。

A suitable geologic model has been made in according to the geologic and productive situation of Guanxia member of Zhongyi area, Gudao oilfield. The reservoir fluid and its influence to production were studied by numerical simulation, the remaining oil distribution was found, the infill and adjusting scheme with their indexes prediction were made. After the scheme was carried out in field, the average oil production in new wells was 10 2 t/d and watercut was 71.8% and the cumulative incremental oil has been 12415 t. The oilfields development effect was improved and gave reference to the similar reservoirs.
