There are many multi-country oil and gas fields, usually stratified fracturing. In addition, the division of oil field development strata,proppant sand manufacturers some belong to a development strata, but reservoir heterogeneity characteristics of strong stratification exists within the layer, which is usually called oil well fracking.
1. Packer layer fracturing
Packer layer fracturing fracturing technology is a widely used at home and abroad, but the job is complicated and costly. Depending on the choice of the type of packer and the tubular string, the following four types.
1) Single-packer for the bottom layer of the hierarchical fracturing fracturing, suitable for all types of reservoirs, especially in deep and large fracturing.
2) double layer fracturing packer can open any oil and gas wells on the radio layer fracturing.
3) bridge plug packer layer fracturing.
4) sleeve packer layer fracturing
