港深 78井是用港海一号钻井平台在浅海地区钻探的一口预探井 ,但该井试油时 ,钻井平台有效使用面积偏小。针对港海一号的具体情况 ,设计了适应平台的地面流程 ,优选了试井设备、优化了井下测试管串、现场化验设备及解释设备 ,保证了两层油气层测试和两次验塞测试的成功
The Hong Kong-Shenzhen 78 well is a pre-exploratory well drilled in the shallow sea area by using the Hong Kong-Hoi-1 drilling platform. However, when the well is tested for oil, the effective use area of the drilling platform is small. In view of the specific situation of the harbor sea one, designed the ground flow that adapts to the platform, optimized the well test equipment, optimized the underground test tube string, on-site laboratory equipment and interpretation equipment to ensure two layers of hydrocarbon test and two plug tests Success
