摘要

垦东405井区位于水深3m、距离陆地3.7km的极浅海区域。发现井试油产油量在22.2t.d-1,为稀油、疏松砂岩油藏,预测地质储量107×104 t。但由于不具备采用人工岛的资源和地面条件,成了边际开发油藏。根据三维地震、测井约束地震反演情况,落实了储层和储量。通过数值模拟、油藏工程和经济评估,优化设计了1口大位移水平井,成功实现了海油陆采,取得了较好的开发效果和经济效益。
Kendong 405 is located in the extremely shallowsea region with water depth of 3m and 3.7 kilometers away from the land.The formation testing production of discovery well is 22.2 tons per day,which is the thin oil and unconsolidated sand reservoir.The calculated original oil in place is 1.07 million tons.The reservoir becomes the marginal development one because it does not possess the resources and surface conditions of artificial island.The reservoirs and reserves have been proved in terms of 3D seismic and logging-constrained seismic inversion.An extended-reach horizontal well has been optimized by numerical simulation and reservoir engineering and economic evaluation.The producing marine oil on land has been implemented and a good economic beneficial result has been got.
