摘　　要：为研究海上高产高含蜡油气井测试工艺优化方案,以东海西湖凹陷某井测试作业中所暴露出的问题为导向,开展西湖高产高含蜡储集层测试问题原因分析和国内外技术调研,同时进行了测试管柱和地面测试流程的流动性保障技术研究及原油燃烧保障技术研究。研究表明地面流程结蜡、大油嘴放喷返排出大颗粒碎屑及大产量原油燃烧导致燃烧头损坏是影响测试的主要原因,因此对测试管柱、地面测试流程及燃烧保障等进行工艺优化,以解决高产高含蜡油气井测试相关问题。In order to study optimization and application of testing technology for high-production and high-waxy well offshore,the causes of the problems with the test of the high-production and high-waxy reservoir in the West Lake were analyzed and the technology at home and abroad was investigated in light of the problems with a well test in the West Lake Sag,East China Sea.At the same time,the research on the fluidity support technology for the test string and the surface test process,and the research on the crude oil combustion guarantee technology were carried out.The results showed that the main causes that affect the test were the wax formation in the surface flow,large particles of backflow debris from the large choke and the damage of the combustion head due to burning of large volume of crude oil.The test string,the surface test flow and the combustion support technology were optimized so as to solve the problems related to high-production and high-waxy well tests.
