摘要
针对碳酸盐岩油藏缝洞储集体距离井眼超过120m以上、井层深度超过6000m以上的超深井储层,目前的酸压工艺不能实现有效沟通远井缝洞发育带的目的。通过开展水力加砂压裂技术研究,具体通过选井选层、地应力及岩石力学参数模拟、压裂液体系筛选、工艺技术设计、裂缝监测与评价等技术的研究及应用,既能保证形成较长的有效裂缝长度,又能保证裂缝高导流能力,通过提高沟通更远处有效储层的机率,达到提高改造储层的效果。
As for the ultra- deep well carbonate reservoir, in which pore reservoir body is more than 120 m away from borehole and well depth is over 6 000 m, current acid - fracturing technology can not realize the goal of effective communicating pore area of the far well. The study and application of hydraulic sand fracturing technologies, specifically including the wells and stratums＂ choosing, stress and rock mechanics parameter modeling, fracturing liquid system＇s screening, technology design, fracture monitoring and evaluation and so on, can assure not only the long effective fracture length but the powerful flow conductivity of the fracture. Through enhancing the probability of communicating the effective reservoir in farther place, the purpose of improving the reservoir reconstruction effectiveness should be reached.
