Technical characteristics of hydraulic jet fracturing:
There is no compaction zone pollution, which can reduce the stress concentration in the near wellbore area.Increasing permeability of near wellbore zone.By using hydraulic jet directional perforation, the injection tools can be accurately designed and manufactured
The location of the joint can make the fracture accurately in the well; the fracture is basically produced in the perforation channel
The direction of crack initiation and the direction of fracture extension are controlled effectively.
It is not necessary to use hydraulic principle to seal fractured fractures.The mechanical packer can realize automatic sealing between layers and reduce tool sand card or operation risk and construction cost of sand burying.
Selective fracturing can be carried out for thin interlayer or collusion layer.
For hydraulic jet fracturing, it is caused by the throttling of nozzles.The displacement of the tubing is low, and the fluid is added from the casing, which not only increases the amount of fluid distribution.
The high cost, but also increase the fracturing truck equipped, it is not a lot of sand. And during the construction of pumping pressure than the general fracturing of about 20MPa, is not suitable for deep well fracturing.
However, the application of this technology can be used for layer selection fracturing of thin interlayer wells, and the well preparation is simple, so it can be used as a powerful supplement for packer fracturing technology.
