摘要
针对超低渗油藏储层改造难度大、油井低产低效的问题,近年来在老井初次改造的基础上,开展井组整体重复压裂技术试验,通过"控制缝长、增加带宽"思路对储层进行大规模改造,建立有效驱替,动用侧向剩余油.现场结果表明,实施井组宽带压裂显著提高了油井的增油效果,单井日增油较常规压裂增加0.77t,措施有效率达到98%.
Abstract
In response to the difficulty of reservoir modification in ultra-low permeability reservoirs and the low production and efficiency,based on the initial modification,the overall repeated fracturing technology of well groups has been carried out.Through the concept of"controlling fracture length and increasing bandwidth"to modify reservoir,which can establish effective displacement and utilize the remaining oil.The results show that the implementation of broadband fracturing in the well group improves production efficiency,with a daily oil production increase of 0.77 tons compared to conventional measures,and the effective rate of the measures reaches 98%.
