摘要
吉林油田长深气田的储层物性较差,非均质性强,潜在地层损害因素复杂;气藏埋深、温度高、地层压力系数变化大;气藏高含CO2,腐蚀严重。随着勘探开发的不断深入,为保证油田安全生产、高效开发,迫切需要一套符合自身特点的压井液体系。以长深气田地质特点为基础,进行了相关处理剂筛选与评价,同时,进行了加量优化,确定长深区块的压井液配方,研制出了低伤害、无固相高温压井液体系,并成功应用于现场作业。
The reservoir in changshen block of Jilin oilfield is characterized with non-homogeneous, complexity of potential damage factor, high temperature of deep gas reservoir and obvious variable of the pressure coefficient, which proves that the reservoir in this area is not of good quality. Meanwhile, high content of CO2 results in serious corrosion. With further exploration and development, to ensure safe production and effectively development of the oil&gas reservoir, it is urgently for a well-kill liquid system suitable for the Jilin oilfield. Take the Changshen block as a research object, a high temperature resistance well-kill liquid system without solid matter and low damage to the reservoir was designed, and applied to field operation successfully.
