Abstract

Abstract:

Perforation technology of low permeability reservoir must be combined with fracturing technology, and the optimization of perforated intervals is one of the key problems. Aimed at the geological characteristics of the northwest area in Junggar basin, a practical optimal method of perforated intervals is presented in this paper, which applies multiple perforation plans, compared these plans with simulation results of these perforation plans and fracturing plan, perforation plan is optimized. This optimal plan can make every layers fractured evenly and strongly and can prevent propagating into the water or interlayer with lower stress. This method is practiced in the northwest area in Jungger basin, combined with separatelayer fracturing of restrict rate and packer, remarkable results are achieved.

Key words: perforation, interval, optimization, separatelayer fracturing, fracturing simulation
