高能气体压裂技术

The High-Energy Gas Fracturing Technology

目前，高能气体压裂（以下简称HEGF）是国内油田增产增注的一项新颖的逐步成熟的工艺技术措施。本文根据材料力学和渗流力学基础理论阐述了HEGF造缝及增产原理，较详细地介绍了俄罗斯HEGF工艺和裂缝几何尺寸计算方法，并对国内外工艺技术进行了比较，指出液体火药ГОС的应用可极大地提高HEGF措施效果，简单介绍了HEGF现场应用情况。

At present, high-energy gas fracturing (HEGF ) is a new technology which is becoming mature gradually in increasing production and injection at domestic oilfields. The paper describes the principle of forming fractuie and increasing production with HEGF and in accordance with the basic theories both mechanics of materials and seepage flow, introduces Russian HEGF technology and the calculation method of fracture size in detail, and also compares the native technology with abroad's. It indicats that the application of fluid's powder of TOC can increase the efficiency of HEGF, also introduces briefly the application effect of HEGF in field.
