    摘要:

    随着国内天然气开采规模的日益扩大和深海开采的进行,由天然气水合物所引起的问题,日益受到了石油天然气研究人员的重视。为抑制天然气水合物的生成,急需研究开发出加量少、效率高的水合物抑制剂。为此,自主合成了新型动力学水合物抑制剂BVP,采用自制评价设备,以四氢呋喃法[THF]对其性能进行了评价。评价结果: BVP加量为0.5%~0.75%时,水合物结冰温度为-8℃,过冷度为-10℃;结合天然气水合物抑制剂PVP做性能对比,BVP的性能明显优于PVP,BVP浊点较PVP浊点提高了27.2℃,相同加量条件下BVP承受过冷度较PVP承受过冷度低2~3℃;结合热力学抑制剂复配,最优复配方案:5%~10%NaCl 0.5%BVP,该复配方案下溶液能够承受过冷度达-12℃~-16℃。

    Abstract:

    During the process of natural gas exploitation and gathering, the equipment and pipe blockage brought about by the formation of gas hydrate has threatened oil gas industry for a long time. A hydrate inhibitor of low dosage and high efficiency is needed to prevent gas hydrate from forming. Therefore, we have developed a novel dynamic hydrate inhibitor BVP of which performance has been evaluated with [THF] by an equipment which is designed by ourselves. The experimental results are: when BVP dosage was 0.5% ~ 0.75%,the freezing temperature of hydrate was -8℃, and the undercooling was -10℃; compared with a commercial gas hydrate inhibitor PVP, the performance of BVP has shown much better performance than that of the former, that is , the cloud point of BVP is 27.2℃ which is higher than that of PVP, under the condition of the same dosage, and the undercooling of BVP is 2 ~ 3℃ lower than that of PVP; the optimal combination scheme is, 5% ~ 10% (NaCl) 0.5%BVP, the undercooling of this combination solution could be -12℃ ~ -16℃.
