An Integrated Drilling Cuttings Utilization Technique in the South Pingqiao Block of the Fuling Shale Gas Field

  • 摘要: 涪陵页岩气田平桥南区块页岩气产能建设过程中产生的钻井岩屑,采用常规方法处理时存在处理费用高、占地面积大和危害环境等问题,为此探索研究了页岩气井钻井岩屑综合利用技术。分析了钻井岩屑的主要危害和目前常用岩屑处理技术的不足,结合现场实际情况提出了水基岩屑随钻固化制砖和水泥窑协同处置油基岩屑等关键技术,形成了涪陵页岩气田平桥南区块钻井岩屑综合利用技术。该技术在JY205-1HF井、JY199-4HF井和JY199-5HF井进行了现场试验,结果表明,采用该技术处理页岩气井钻井岩屑成本低,且清洁、环保,经济效益好。研究认为,该技术可有效解决常规钻井岩屑处理技术经济投入高、环保压力大等问题,为资源化利用钻井岩屑、绿色开发页岩气田开辟了新途径,具有良好的应用前景。

     

    Abstract: In order to solve the problems of high cost of drilling cuttings disposal and environmental protection concerns during the productivity construction of south Pingqiao Block in Fuling Shale Gas Field, an integrated utilization technique of shale gas drilling cuttings was studied. The study included analyzing the hazards of drilling cuttings and the shortcomings of existing common cuttings treatment technologies,. Fabricating bricks from the cuttings was considered a key technology. The study included processes such as curing brick making for water-based cuttings while drilling and co-processing of oil-based cuttings by cement kiln were proposed, the actual technique to be determined based on the actual conditions of the cuttings generation. The proposed integrated utilization technique of shale gas cuttings was field tested in Well JY205-1HF, JY199-4HF and JY199-5HF, the test results suggested that this shale gas cuttings disposal technique was cost efficient, clean, environmentally friendly and economically beneficial. Studies showed that this technique could effectively solve the problems of high economic investment and environmental risk of the existing cuttings treatment technologies. It opened up a new way for the resource utilization of drilling cuttings and the construction of green shale gas field. It has a good outlook for application and implementation in the field.
