筛管完井爆燃压裂技术可行性研究
|
摘要
运用地面打靶实验方法,利用不同类型和用量的火药进行筛管完井爆燃压裂实验,并检测压裂后水泥靶中筛管挡砂精度的变化,对筛管完井爆燃压裂技术可行性进行了研究。研究表明:星孔筛管不适合进行爆燃压裂,存在较大风险;绕丝筛管受限于检测方法,其适用性还需进一步研究;复合筛管在满足火药类型、火药用量、峰值压力等限制条件下可进行爆燃压裂。在中国海上油田惠州26-1油田20sb井进行了现场试验,效果显著,一口关停2 a的井成功复产,并且压裂枪完好,油井不出砂,验证了复合筛管完井在一定限制条件下实施爆燃压裂技术的可行性。该技术对国内外类似油田的开发具有借鉴意义。
The feasibility of liner-completion deflagration fracturing technology was investigated by using surface target practice experiment method,conducting liner-completion deflagration fracturing experiment with different type and amount of gunpowder and testing variation of sand retention accuracy of liner in cement target after fracturing. The research showed that star hole liner was not applicable to deflagration fracturing and poses high risk,that applicability of wire wrapped liner needed further investigation due to the limitation of measuring method and that composite liner was suitable for deflagration fracturing when gunpowder type,gunpowder volume and peak pressure met requirements. Field test was done on well 20 sb in the offshore Huizhou 26-1 oil field in China,with signification effect. One well which had been shut in for 2 a resumed production successfully,with intact fracturing gun and no sand production from oil wells. The field test verified the feasibility of deflagration fracturing technology used in composite liner completion under certain limitations. This technology provides reference for the development of similar oil fields around the world.
