摘要
针对以往压裂支撑剂优选方法的局限性,进行了研究改进,其要点包括长期导流能力的测试与评价分析;测试介质由原用的蒸馏水改为压裂液破胶液;研制了可考虑长期导流能力及应力敏感性的压裂井动态预测模型。研究结果表明,即使两种支撑剂的长期平均导流能力完全相同,但如初期导流能力及其随时间的下降幅度不同,则优选的结果也不同。这比以往的研究有重要改进,并会在一定程度上提高压裂的效果。
On the basis of the limitation of optimum seeking method of fracturing proppant in past,the paper researches and improves the optimum seeking method of proppant,including:①evaluation testing of long term flow conductivity;②testing medium has changed from distilled water to fracturing fluid breaking agent,;③performance forecasting model of fractured well is developed which can conside long term flow conductivity and stress sensibility.Through field application,the results show that the optimum seeking method of proppant improved can increase postfracture response.
