在双河油田压裂方案优化中,综合应用了油田地质、油藏工程、经济评价、压裂施工参数及压裂施工方式选择,以及国内外低渗透油田开发的成功经验。尤其是油藏数值模拟,为优化设计提供了技术依据和评价压裂改造的可实施性。应用油藏数据模拟,模拟不同缝长下的压后累积产量,确定最佳支撑缝长,然后用裂缝模拟软件设计实现最佳支撑缝长所需的施工规模及裂缝尺寸。经现场实施,监测的裂缝尺寸和历史拟合的裂缝尺寸与设计的裂缝尺寸基本符合,取得了较好的压裂效果。

During the optimized fracturing of Shuanghe Oilfield , the petroleum geology , reservoir engineering , economic evaluation , selection of operation way and parameters and some domestic and foreign low permeabile development experience are comprehensively applied. Especially , the reservoir numerical simulation supplies technical basis and fracturing stimulation implement. We apply reservoir numerical simulation to simulate production of different f racture length after fracturing , and determine the optimum fracture length , and then design expected operation scale and fracture size of optimum propped fracture length with fracture simulator.
