摘要： 深水钻井中,水合物的大量生成与聚集是引起防喷器堵塞等事故的直接原因。利用水合物模拟实验 装置,模拟了深水钻井动态环境,对深水水基钻井液常用添加剂进行了水合物生成实验研究。以水合物开始大量生成的时间为评价标准,分析了常用加量下深水钻井液添加剂抑制水合物生成效果。结果表明,聚合醇SD灢301可显著推迟水合物大量生成的时间,其抑制效果优于常用水合物动力学抑制剂PVCap;聚阴离子纤维素PAC灢LV、生物聚合物XC、羧甲基纤维素CMC灢LV 以及动力学抑制剂PVP 也具备一定的抑制效果;而部分水解聚丙烯酰胺PLUS、氨基聚合物SDJA以及磺化酚醛树脂SD灢102的抑制效果并不明显。

Abstract: The significant formation and aggregation of hydrates would lead to blockage of BOP stacks during deepwater drilling. The process of gas hydrate formations in the presence of common additives used in deepwater drilling fluids were investigated in the simulating condition of deepwater by utilization of a simulating device. The hydrate inhibition properties of additives were analysed according to the time of significant hydrate formation. The results show that polyglycol(SD301) could delay the significant hydrate formation noticeably, and it performed better than kinetic hydrate inhibitor(PVCap). Polyanionic cellulosic polymer(PACLV), biopolymer(XC), carboxymethyl cellulose(CMCLV) and kinetic hydrate inhibitor(PVP) could also control the hydrate formation to some extent. While the inhibitions of partially hydrolyzedpolyacrylamide(PLUS), polyamine(SDJA) and sulfomethal phenolaldehy resin(SD102) could be ignored.
