摘要
从一维两相渗流理论出发,综合考虑堵剂在纵向的分布规律和堵剂进入地层后对储层物性的改变,推导出了计算堵剂在不同渗透率地层中进入深度的公式,从而可以较准确地计算出在堵剂到达调剖半径时的堵剂用量。江苏油田某区块的实际计算与施工效果表明,本文方法计算结果准确可靠。
From the theory of biphase percolation in one dimension,the vertical distribution of blocking agent and the changes in reservoir petrophysics due to blocking-agent plugging are comprehensively considered,and then a formula to calculate the entering depth of blocking agent into formations with different permeability is derived,by which it is possible to calculate more accurately the blocking agent volume required when its reaching to the profile correction radius.An actual calculation by the formula and its engineering effects in a block of Jiangsu oilfield have shown that this new method is accurate and reliable in calculation.
