摘要:
 南海海域稠油油藏测试井普遍非自喷，常规DST测试管柱无法在半潜式平台上实现测试作业。对测试管柱、射孔工艺、工作制度及地面稠油计量处理等关键技术进行优化，研发出一套适用于半潜式平台稠油测试的螺杆泵电加热、隔热油管保温、高效轻型井口补偿系统，应用于南海X井浅层疏松稠油井测试实践中，有效提升地面井口温度至53℃，实现了油井自喷，成功获取地层特性参数及流体样品，同时增强了测试井口提升补偿系统吊装的安全性及高效性。该技术的成功应用为南海稠油油藏的勘探开发提供了有力的技术支撑。
Abstract:
 The test wells of heavy oil reservoirs in the South China Sea are generally unable to selfspray, and the conventional DST test string cannot achieve the purpose of test operation on the semisubmersible platform. In this paper, the key technologies such as test string, perforating process, working system and surface heavy oil measurement and treatment are optimized, a set of screw pump electric heating, heat insulation tubing insulation, high efficiency and light wellhead compensation system for heavy oil test of semisubmersible platform is developed. In the test practice of shallow unconsolidated heavy oil Well X in Nanhai, the wellhead temperature was effectively raised to 53℃, the selfspray of oil well was realized, the formation characteristic parameters and fluid samples were obtained successfully, and the safety and efficiency of lifting compensation system of test wellhead were enhanced. The successful application of this technology provides strong technical support for the exploration and development of heavy oil reservoirs in the South China Sea.
