Optimization and application of PHP casing hydraulic packer in Tahe oil field
-
摘要: PHP套管液压封隔器已在塔河油田广泛使用,但随着油田勘探开发的深入,对封隔器的耐温耐压性能提出了更高的要求。通过对封隔器本体增加壁厚、胶筒耐温升级等措施,改进出PHP-2封隔器。该封隔器具有耐压差高、耐温高、可回收、较进口永久式便宜等特点,在塔河油田勘探开发中具有广阔的应用前景。Abstract: PHP casing hydraulic packer has been widely used in the Tahe oil field; however, with the deepening of oilfield exploration and development, its heat and pressure resistance need improment. We use thicker packer wall and more heat resistive plastic tube to upgrade PHP-2 packer, which is outstanding for high pressure diffe-rence resistivity, high temperature resistivity, recyclable and less cost compared to imported permanent packer. The optimized packer has a broad application prospect in the Tahe oil field.
