摘要
四川油气田油气储层在地质上呈低渗、低孔、非均质特征 ,且大多数低渗油气藏具有深埋、高温、高压、高含硫、多产层等特点 ,压裂酸化是提高油气开采效果的一种重要手段。本文概述了四川油气田 4 0多年来形成的各种压裂酸化液体体系及应用情况 ,详细介绍了“九五”期间新发展的压裂酸化液体技术 ,包括改进的胶凝酸体系、降滤失酸液体系、油藏加砂压裂液体系、低温压裂液体系、高效化学助排技术以及压裂液现场质量控制与返排残液分析技术等。
The research work in the acidizing and fracturing has been done for more than 40 years in Sichuan oil and gas field. We have made distinct progress over these years, especially since l980 th . This paper gives a summary for most of the additives , fluids systems and their main performance and on - the - spot application. It introduces the developed technology during the last 10 years in detail.
