摘要: 为克服传统胍胶压裂液溶胀速度慢、现场配制时间长、破胶后残渣含量高等缺点,研制了一种多元改性速溶胍胶压裂液.在清水中加入一定量的羧甲基和羟丙基双改性胍胶及杀菌剂、黏土稳定剂、交联剂等处理剂,配制得到多元改性速溶胍胶压裂液.室内试验表明,该压裂液溶胀速率快,1 min溶胀率已达到3 min溶胀率的94.7%,溶胀速度较羟丙基速溶胍胶压裂液提高了18.75%;水不溶物含量极少,较羟丙基速溶胍胶压裂液降低了88.46%;破胶后的残渣含量降低超过71.0%,对支撑剂导流能力的伤害降低了62.0%,对岩心渗透率的伤害降低了53.8%,其综合性能达到现场施工要求.现场应用表明,多元速溶改性胍胶压裂液能够满足大规模水平井压裂施工的要求,并能为低渗透、特低渗透储层的有效开发提供技术支撑.Abstract: Traditional guar fracturing fluid is disadvantageous because of its characteristics of slow swelling, long on-site preparation times, and high residue content after gel breaking. In order to overcome the problems, a certain quantityof double modified carboxymethyl + hydroxypropyl guanidine gum and other additives (e.g. bactericide, clay stabilizer, and crosslinker) were added in water, making its comprehensive performance to meet the site construction requirements. Thus, a multicomponent modified instant guar fracturing fluid system was developed. The new fracturing fluid system had a fast swelling rate, reaching more than 94.7% final viscosity in one minute, and a low water insoluble matter content, it was lowered by 88.46% than the hydroxypropyl guar; the residue content reduced by 71.0%, the flow conductivity of propping agent damage dropped by 62.0% and the core permeability decreased by 53.8%. Laboratory tests and site operations demonstrated that the multicomponent modified instant guar fracturing fluid could satisfy the online mixing requirements of the large-scale fracturing operation used in horizontal wells, and could provide technical support for the effective development of low permeability reservoir.
