摘要:

低渗透储层的射孔技术必须配合压裂增产改造技术而开展,其中射孔层位优化是其关键问题之一。针对准噶尔盆地西北缘储层地质特性,提出了一种射孔层位优化的实用方法,即采用多种射孔方案,通过对不同射孔方案与压裂方案的模拟结果进行比较,优选射孔方案,尽量使各层都得到均衡、有力的改造,并且防止压裂时压窜目的层上、下水层或应力较小的夹层。该方法在准噶尔盆地西北缘勘探实践中,结合限流法分层压裂技术和封隔器分层压裂技术进行应用,取得了显著成效。

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
