摘要
SW103区块位于十屋油田北部梨树断陷代家屯岩性圈闭内,以水下分流河道沉积为主,主要为粉砂岩、细中砂岩为主,储层裂缝分布较普遍,充填程度较高。本文从类比国内外同类型油田注采井距开发效果入手,进行可行性研究,并对井网形式、合理注采井距、压力保持情况及注水开发效果开展研究实验,为实现超低渗油藏经济有效动用提供可靠的研究基础。
The SW103 block is located in the northern part of Shiwu oil field, Li Shu rift, Daijiatun lithologic trap, showing underwater distributary channel deposits; siltstone and fine sandstone are dominating. Distribution of reservoir fracture is common and the most are filled. Based on the analogy oilfield injection-production well spacing development results at home and abroad, we were engaged in feasibility study, including wells network pattern, reasonable flooding-production well spacing, pressure maintenance and water injection development effect research experiment, it provided reliable research foundation in order to achieve economic and effective use of ultra-low permeability reservoirs.
