During the fracturing for low pressure and low permeability gas reservoirs, there are some main problems in conventional hydroxypropylguar - organic boron cross-linking system: Firstly, the water-lock damage to low pressure and low permeability gas formations by filter liquor; Secondly, the reason for alkali-sensitive damage in alkali-sensitive reservoirs is that conventional hydroxypropylguar - organic boron cross-linking fracturing fluids were cross-linked under alkaline environment, while the permeability of reservoirs is reduced greatly; Thirdly, the formation pressure is low, and the energy of flow back is not enough, at present, the main measure in oil fields is "injecting with liquid nitrogen", but this technique increased the cost of fracturing, making great troubles in operating, and leaving the liquid nitrogen also is a big problem.
在低压低渗透气藏的压裂改造过程中,常规羟丙基胍胶-有机硼交联压裂液体系存在的主要问题,一是压裂液滤液对低压低渗透气层造成的水锁损害;二是常规羟丙基胍胶-有机硼压裂液是在碱性条件下交联的,对碱敏性储层造成碱敏损害,降低储层渗流能力;三是地层压力低,压裂液返排能量不足,当前各油田采取的措施主要是&液氮伴注&技术,但是&液氮伴注&技术增加了压裂的费用,而且液氮存放也存在较大问题。
