摘要

摘要: 为满足水平井体积压裂技术中连续混配作业要求，并缓解常规羟丙基瓜胶原料供给压力，开展快速水合瓜胶压裂液体系的研究。探索对瓜胶原粉进行细度分级和表面处理，使其能够快速分散水合，替代常规羟丙基瓜胶，为水平井体积压裂的压裂液体系提供一种新的路径。本文优选配套杀菌剂，压裂液基液72 h稳定性提高70%；制备配套交联剂，有效降低稠化剂浓度，解决基液黏度高、冻胶交联速度快、残渣含量高等问题，改善混砂状态、施工摩阻和储层伤害。研究结果表明，快速水合瓜胶压裂液的3 min溶胀率大于90%，72 h基液黏度保持率在85%以上，交联时间30～180 s，在120℃、170 s^-1剪切1 h后的黏度达200 mPa · s，破胶后残渣含量小于400 mg · L^-1，可适用于30～120℃储层的压裂作业。已在新疆油田开展5口水平井连续混配现场试验，施工及生产效果良好。

Abstract: In order to meet the requirements of continuously mixing fracturing fluid of volume fracturing for horizontal wells and alleviate the shortage of HPG, the paper studied the FHG fracturing fluid. Through the fineness classification and surface treatment of guar gum, it could quickly disperse and hydrate, and replaced the conventional quick soluble HPG, which provided a new path for the fracturing fluid system of volume fracturing for horizontal wells. In this paper, the matching bactericide was optimized, the stability of fracturing fluid was increased by 70% in 72 hours; the matching crosslinking agent was prepared, which could effectively reduce the concentration of thickener, solved the problems of high viscosity of base fluid, fast crosslinking speed of gel, high residue content, and improved the sand mixing state, construction friction and reservoir damage.The results showed that swelling rate of FHG fracturing fluid was more than 90% in 3 minutes, viscosity retention rate of 72 h base fluid is over 85%, the viscosity reached 200 mPa·s after shearing for 1 hour at 120 ℃and 170 s^-1, and the residue content after breaking was less than 400 mg·L^-1, which could be applied to fracturing operation at 30-120℃. The fracturing fluid had been used in 5 horizontal wells of Xinjiang Oilfield, and the effect of operation and production was good.
