测试资料在油藏描述中的应用

Application of test data in reservoir description

油藏描述是一项综合性很强的工作,需要运用大量的各种动、静态资料数据作为依据。及早识别油(气)藏规模,对于正确认识油藏,加速油气田的勘探开发至关重要。正确认识油(气)藏规模的关键之一是搞清油(气)水系统。一方面,可利用试油所获取的压力资料绘制压力-深度关系曲线来判断油气藏压力系统,以确定储层的压力系统是否一致及预测储层中不同流体界面的原始位置。另一方面,确定了沉积盆地的地温-地压系统模式,有利于分析流体的运移能力及油气藏的储集特征。

Reservoir description is a comprehensive work,which requires the use a large number of dynamic and static data as the basis.It is very important to identify the scale of oil(gas)reservoir as soon as possible for correctly understanding the reservoir and accelerating the exploration and development of oil and gas fields.One of the keys to correctly understand the scale of oil(gas)reservoir is to clarity the oil(gas)water system.On the one hand,the pressure-depth relationship curve can be drawn from the pressure data obtained from oil testing to determine the pressure system of oil and gas reservoirs,so as to determine whether the pressure system of the reservoir is consistent and predict the original position of different fluid interfaces in the reservoir.On the other hand,the geothermal-geopressure system model of sedimentary basin is determined,which is conducive to analyze the fluid migration ability and reservoir characteristics of oil and gas reservoirs.
