摘要
体积压裂作为近些年发展起来的一种储层改造技术,具有大排量、小砂比、造缝能力强的特点.目标区属于致密油区,为特低渗油藏,储层非均质性强,岩性致密,常规压裂效果有限.通过体积压裂对储层进行改造,增大了油层渗流能力,提高了油井产量,对油田致密油区勘探开发具有重要意义.
As a kind of reservoir reconstruction technology developed in recent years,volumetric fracturing has the characteristics of large displacement,small sand ratio and strong seam forming ability. The target area belongs to the dense oil region and the extra low permeability reservoir. The reservoir heterogeneity is strong,the lithology is dense,and the conventional fracturing effect is limited. Through the transformation of reservoir by the volume fracturing technology,the seepage capacity of reservoir and the oil well production is increased,it is of great significance to the exploration and development of dense oil region in oilfield.
