摘要
YG1井为薄互层发育的低孔低渗储层,常规的压裂技术难以取得有效的增产效果。为了取得更好压裂改造措施,采用了多簇射孔+桥塞分层压裂工艺技术,并对支撑剂粒径组合及加量、压裂液进行优化,在此基础上形成该井的分层压裂工艺技术。经现场试验证明,该工艺技术改造取得了良好的增产效果,值得在类似储层中推广使用。
Well YG1 is a low porosity and low permeability reservoir with thin interbeds.Conventional fracturing technology is difficult to achieve effective stimulation effect.In order to obtain better fracturing modification measures, multi-cluster perforation+bridge plug stratified fracturing technology was adopted, and the proppant size combination, dosage and fracturing fluid were optimized,based on which the stratified fracturing technology of the well was formed. Field tests show that the technology has achieved good stimulation effect and is worth popularizing in similar reservoirs.
