| 摘 要： | 颗粒荧光技术可快速探测储层颗粒中油包裹体和颗粒表面吸附烃, 能较好地反映储层中油气包裹体丰度及油气性质,可以很好地确认现今油藏和古油藏,有效判别油层、水层、油水过渡带以及古油水界面。用颗粒荧光分析技术,分析了依合2A井志留系柯坪塔格组近20块样品,发现该方法可以较好地识别柯坪塔格组致密砂岩储层中的油层、油水过渡带和水层,为致密砂岩储层油水层判别提供了一种新方法；利用该技术还在志留系柯坪塔格组上段底砂岩中识别出一套含油层,表明该技术具有较好的推广和应用价值。

| Abstract: | The grain fluorescence technique which can quickly detect oil inclusions within reservoir grain and adsorption surface of reservoir grain is applied. The inclusion of oil and gas reservoir and hydrocarbon abundance of nature is well reflected by the method, which can also effectively determine the recent reservoir, the ancient reservoir, the water level, water transition zone and ancient oil-water interface. It is found that the method can effectively identify the reservoir, oil-water transitional zone and water layer of Silurian Kepingtage Formation tight sandstone reservoirs by analyzing nearly 20 samples of Silurian Kepingtage Formation in Well Yihe2A. It is a new method in available to determine oil-water layer in tight sandstone reservoir. In addition, it also has identified a set of oil layers in the bottom sand of the previous member of Silurian Kepingtage Formation. It is shown that the grain fluorescence technique has good promotion and application value. |
