锦98块杜家台经过30多年的开发,采出程度已高达27.56%,油井挖潜难度越来越大。针对产量递减的不利形势,通过精细地质研究,引进先进的酸化冲击解堵技术来改造低渗油层,利用侧钻技术提高油井利用率,通过改变注水方式,并合理复产一批有潜力的停产井,达到了提高开发水平的目的,为该类油藏的开发提供了经验。
Jin 98 Dujiatai after 30 years of development, mining has reached 27.56% of the degree, more difficult to tap the potential wells. In view of the unfavorable situation of decreasing output, through the fine geological research, the advanced acidification impact plugging technology is introduced to transform the low permeability oil reservoir, the sidetrack drilling technology is used to improve the oil well utilization rate. By changing the water injection mode, Well, to achieve the purpose of raising the level of development, for the development of such reservoirs provided experience.
