吉林油田松原采气厂大老爷府油田属于典型的低渗透储层,在通过钻井过程中,由于冲砂液选择的不当,很容易造成地层的坍塌、漏失等情况,一旦处理不当很容易造成事故或地层的污染,选择哪种冲砂液,采取哪种冲砂液性能参数,是确保钻井安全,提高单井生产能力的重要因素,因此研究“安全、健康、高效”的冲砂液,成为今后冲砂液处理剂和冲砂液的开发方向成为研究的重要内容。冲砂液性能的提高能有效保护油气层,提高气井单井采收率。
The Songyuan gas production plant in Jilin Oilfield Dadioyu Oilfield is a typical low permeability reservoir. During the drilling process, due to the improper choice of red sand, it is easy to cause the collapse and leakage of the formation, which can easily cause an accident if handled improperly Or stratum pollution, which kind of flushing fluid to choose and which kind of flushing fluid performance parameter to take is an important factor to ensure drilling safety and improve single-well productivity. Therefore, researching the “safer, healthier and more efficient” flushing fluid , Become the red sand processing agent and red sand development direction has become an important part of the study. Flushing sand performance improvement can effectively protect the oil and gas layers, improve gas well single-well recovery rate.
