摘要

高能气体压裂作为具有独特增产机理的一种油气井增产技术,已在长庆油田各产油区进行了广泛应用。分析了 2 6 8井次的HEGF施工效果,对其适应的地质条件和影响效果的主要因素进行了分析研究,给出了选择高能气体压裂药量大小的原则,找出了适合该技术的地层条件。经现场试验,证明是有效的、科学的,极具推广价值。

Abstract

As a oil and gas stimulation, High Energy Gas Fractured(HEGF) was used in Changqing Oilfield widely. With the HEGF construct effect of 268 wells, the adaptive formation conditions and the main affect factors were studied. The principle of remedy quantity elected in HEGF was presented. The adaptive formation conditions of this technology were found. After field testing, it was proved that the technology is effective, scientific and valuable.
