摘要
埕岛油田进入综合调整阶段后,研究形成了一套基本的开发调整技术政策,并已在个别区块实施。通过对已实施区块的跟踪,对已有的开发调整技术政策进行了评价,认为层系细分能切实减小油层干扰,提高采油强度;井网加密后随着井距的缩小和井网形式的改变,注采对应率和水驱储量控制程度大幅提高;通过油井提液,单井产量得以明显提升;通过应用水平井,实现了储量的有效动用,提高了单井产能。综合分析认为现有的调整技术政策能够满足埕岛油田在该阶段高效开发的需求,也可以为后续区块及海上相似油田的的调整提供借鉴。
During the stage of comprehensive adjustment in Chengdao Oilfield,a set of basic development adjustment technology policy was formed and used in some blocks.Through a trace study and analysis of adjusted block,the policy was evaluated which indicated that subdividing series of strata can effectively decrease the interference between layers and improve oil production.Infilling well pattern can increase the injection production rate and water drive control of the reserves.Improving liquid quantity can improve individual well productivity.Through the application of horizontal wells can achieve an effective use of the reservoir and improve oil recovery rate.Comprehensive analysis proved that the existing technology policy can meet the demand of an efficient development in this stage of Chengdao Oilfield as well as provide some experiences for the following adjustment blocks in Chengdao Oilfield and similar oilfields.
