摘要
Abstract
According to the geological structure of Bohai oilfield in unconsolidated sandstone with viscous oil,slim hole lateral drilling wells are completed.3.5 in large diameter perforator is selected to optimize the design of well completion technology,and the colonnade security is evaluated by software of column dynamic mechanical analysis,while using the directional engineering software to simulate the column depth correction,and perforation optimization software for casing strength is used after perforation analysis.The results show that the slim hole perforation technology in unconsolidated heavy oil sandstone fracture filling in completions is solved successfully.At the same time,the pressure drop in the near wellbore area is reduced effectively and pressure difference in the same yield production.Construction process is safety and reliable,and this technology achieves the purpose of insand control stability.关键词
