当前针对物理模型饱和度分布的研究主要针对于一维小岩样和二维小薄模型,针对大厚高压油藏物理模型的方法无人涉及.针对大厚高压油藏物理模型的特点,选取γ射线吸收法和lambert定律进行单个测试点的饱和度测量和计算,然后利用二维数控移动定位系统完成对整个物理模型所有测试点饱和度的测量和计算,最终利用数学插分方法得到油藏物理模型的饱和度分布等值线图,实现对大厚高压油藏二维饱和度分布的预测.通过单点精确度实验及简单验证实验研究表明,利用γ射线吸收法预测大厚高压油藏二维饱和度分布可行性强.

Current research on saturation distribution of physical model focuses on the one-dimensional small rock sample and two-dimensional thin model,and research on high-pressure and large-thick reservoirs model has been involved. In this paper, the timing stable gamma ray test to each model grid node is implemented with high precision two-dimension Computerized Numerical Control(CNC)mobile positioning system,and then the saturation of each grid node is calculated through Lambert Law. Afterwards,reservoir saturation profile is obtained using mathematical drawing method and the prediction of saturation distribution measurement in high-pressure and big-thick reservoir physical model is finally realized. After a single point testing and a simple replication experiment,this method is proved to be feasible and accurate and significant to predict the saturation distribution of high-pressure and large-thick reservoir model.
