摘要
南海西部海域新发现的含油气构造探井、评价井数量少,获取PVT样品成本高昂,且面临易脱气、易挥发、易凝析、组分缺失、样品污染、样品少和含水量高等诸多难题。在南海西部海域PVT取样统计分析的基础上,总结出了复杂条件下PVT取样的经验和适合海上油气藏PVT取样的技术对策。
For the structures newly discovered in the western South China Sea,PVT sampling is high in cost due to less exploratory and appraisal wells,and there are several difficulties such as degassing,volatilizing,condensation,lossing components,pollution,small sample and high water cut.On a basis of statistically analyzing PVT sampling in the western South China Sea,we have summed up experiences in PVT smpling under complex conditions and developed a technical solution for PVT sampling suitable to the offshore oil and gas reservoirs.
