摘要
为高效开发低渗透油藏,分析了目前低渗透储层钻井存在的储层保护问题及钻井技术现状。低渗透储层伤害主要包括固相颗粒侵入、液相侵入造成储层敏感伤害、储层水相圈闭伤害和乳状液堵塞等,其中以水相圈闭伤害为主。适合胜利油田低渗透储层的钻井技术较多,但以多分支水平井的开发最为成功,须加强各种钻井技术的联合使用和新型完井液技术的研究。开发低渗透油藏应注重多项新技术的配合应用,并加强储层保护措施管理。
The reservoir protection issues and drilling technology situation were analyzed for high-efficiency development in the low permeabilityreservoirs.Many kinds of reservoir damages have encounteredwhen drilling in the low permeability reservoirs,including solid particle invasion,sensitive damages induced by liquid invasion,liquid entrap in narrow pore throat,plugging by emulsions and so on,in which,the liquid entrap is the main damage type. There are many drilling technologies applicable to the low permeabilit...
