The oil density at the bubble point is an important thermodynamic property required in reservoir simulation and production engineering. A higher-accuracy estimate of this property would improve the accuracy of reservoir and production engineering calculations. The bubble point oil density is obtained either from separator tests of reservoir fluids or from differential gas liberation tests. A new procedure utilizing separator and differential tests is proposed whereby the experimental data yield a unique value with high accuracy for the bubble point oil density. A consistent correction of other PVT properties, which are influenced by the bubble point oil density, is required to reflect the unique density value. A quantitative quality control index is defined to measure the quality of PVT laboratory reports. This is achieved by utilizing the unique property of the bubble point oil density, which is usually ignored.

储层条件下含气饱和油浓度的测定及PVT实验室质量控制指标的建立

气泡点的油密度是储层模拟和生产工程中要求的重要热力学性质。对该属性进行更高精度的估计将提高油藏和生产工程计算的准确性。泡点油密度可以通过储层流体的分离器测试或通过差分气体释放测试获得。提出了一种利用分离器和差动测试的新程序,从而使实验数据得出的唯一值具有很高的起泡点油密度精度。为了反映唯一的密度值,需要对受气泡点油密度影响的其他PVT特性进行一致的校正。定义了定量质量控制指标,以测量PVT实验室报告的质量。
