地震信号的速度和振幅受油气储层的岩石和流体性质的控制。因此,要成功地对油藏开发进行4-D地震监测,就必须详细了解储层的岩石物性和储层流体之间物性与相态特征的关系。将这些资料与其它油藏描述资料结合起来,就能准确地确定储层流体及其界面的位置。目前,一些实验室正在利用新的先进的岩心和流体分析技术,为石油公司提供4-D地震所需的有关岩石和流体的精确资料,以帮助勘探开发公司用精确的4-D地震油藏监测来改进油藏管理,提高油气田的最终采收率。
The velocity and amplitude of the seismic signal are governed by the rock and fluid properties of the oil and gas reservoir. Therefore, to successfully monitor 4-D earthquakes in reservoir development, it is necessary to understand in detail the petrophysical properties of the reservoir and the relationship between reservoir fluid properties and phase behavior. By combining these data with other reservoir description data, the reservoir fluid and its interface can be precisely located. Currently, some laboratories are using new and advanced core and fluid analysis techniques to provide oil companies precise data on rocks and fluids required for 4-D earthquakes to help exploration companies use accurate 4-D seismic reservoirs Monitoring to improve reservoir management and improve ultimate recovery of oil and gas fields.
