Abstract

The tight and thick sandstone reservoir, which is represented by Huaqing oilfield, was stimulated by the separated layer fracturing technology in the early period which produces discharge multi-channel between the pay formation and wellbore. For the conventional refracturing technology, the combination of tubing and packers is employed to treat the target layers in sequence. Nevertheless, this conventional technology is confined by the size of the tubing so that the maximum pumping rate can only reach to 3 to 4m³/min. It can’t meet the requirement of high pumping rate of hybrid fluid SRV fracturing that the treatment effort is not optimum and the stimulation efficiency is very low. In this article, in order to resolve the refracturing problems above for old wells, we introduced a state-of-art downhole releasing separated layer volume fracturing technology and support tools. By applying the releasing tool assembly and exclusive fishing tools, some goals can be easily achieved: to realize the efficient isolation between target layers, to protect the casing while fracturing, to meet the pump rate requirement of SRV fracturing of 11m³/min. We deployed the pilot field experiment of Huaqing oilfield and realized the “separated layer multistage SRV fracturing” of tight and thick reservoir. The result shows that the initial production rate of trial wells increases by 2.42t/d. The field test indicates that this technology presents some advantages such as high pump rate, simple tool assembly, easy operation and low operation risk.
