石油流体弹性参数的实验研究
|
摘要
油气开采活动会引起油气藏的性态发生变化,如果对变化过程不甚了解,可能会造成地震资料的错误解释。为此,利用胜利油田和塔河油田的12份原油样品(轻质油6份。重质油6份),以及配制的8份含溶解气的石油样品,在实验室测量了样品的地震特征,分析了温度、压力和溶解气对石油速度和密度的影响规律。利用已知石油的地面密度、气油比、气体密度等参数建立了石油速度和密度计算模型。将计算结果与B-W模型的计算结果进行了对比,结果表明,由本模型得到的速度和密度更符合实验数据。
Hydrocarbon exploitation will change the composition and physical properties of fluid in the reservoir.Little knowing about such changes may lead to an incorrect seismic interpretation.So twelve samples of crude oil (six light oil samples and six heavy oil samples) from Shengli oilfield and Tahe oilfield together with eight prepared dissolved-gas oil samples were used to measure the seismic properties and analyzed the affect of temperature,pressure and dis- solved gas on petroleum velocity and density.The calculation mod- el for petroleum velocity and density was established by utilizing the known parameters such as the density of petroleum on surface, the gas/oil ratio,and the density of gas.The computational solu- tion is compared with the result from Batzle-Wang (B-W) model, showing that the velocity and density obtained from our model are more coincident with experimental data.
