摘　　要：尼日尔G油田属于复杂断块油气藏,具有油气并存、存在多套压力系统的特点,开发评价面临评价时间紧,气顶范围不清楚,储量规模不确定,开发决策困难的挑战。地层压力测试资料可以通过定量评价油气藏的压力系统,确定流体性质及流体界面,对油气藏分布范围进行预测。G油田成功的油藏评价实践证明,压力测试成果的应用加快了油藏评价进程,对于转入开发阶段制定合理开发决策具有重要意义。G Oilfield of Niger belonged to a complicated fault block reservoir with both oil and gas in multiple pressure systems.Reservoir appraisal faced the challenges of uncertain gas cap area,uncertain reserves,hence it was difficult for making right development decisions in so short time.RFT pressure test data could be utilized determine fluid properties and fluid contacts and predicting reservoir distribution ranges through the evaluated pressure systems.Its successful use in G Oilfield indicates that the result of the pressure evaluation speeds up the progress of reservoir appraisal.It provides an important basis for development decision making when the oilfield is turned to the development stage.
