试油动态资料在海西南地区的应用

Application of the Well Test and Production Data in the West-South Sea Region.

海西南地区油藏类型比较复杂 ,主要是由于该区裂缝复杂造成的。经对该区 6口井 8层试井资料分析 ,得到裂缝型油藏 (包括宽而长的裂缝型油藏、压裂后形成长裂缝型油藏 )及复合型油藏参数 ,并确定了该区的主裂缝。通过分析该区的试采井资料 ,得到了指数式产能方程、二项式产能方程及油井产能递减方程 ,同时计算了单井控制可采储量。

The reservoir type is so complex in the west south sea region due to the complex fracture in the region.After analyzing 8 layers test data in 6 wells,we get the reservoir parameters of the nature fractured reservoir and the composite reservoir and the main fracture direction in this region.By analyzing the production test data,we get the index production equation,binomial production,production degression equation and the single well control reserve.
