【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。
[Abstract]:In this paper, using the surface shooting experiment method, using different types and dosage of gunpowder to carry out the test of sieve tube completion deflagration fracturing, and detecting the change of sand retaining precision of sieve tube in cement target after fracturing, the feasibility of sieve tube completion deflagration fracturing technology is studied. The results show that the starhole sieve tube is not suitable for deflagration fracturing, there is a great risk, the wire wound sieve pipe is limited by the detection method, and its applicability needs further study; the composite sieve pipe can satisfy the powder type, the dosage of gunpowder, Deflagration fracturing can be carried out under limiting conditions such as peak pressure. Field tests were carried out in the 20sb well of Huizhou 26-1 oilfield, Huizhou oilfield, China. The results show that a well closed for 2 years has been successfully re-produced, and the fracturing gun is in good condition and no sand can be produced from the well. The feasibility of deflagration fracturing under certain limited conditions is verified. This technology has reference significance for the development of similar oil fields at home and abroad.
