摘要
水力压裂、酸化压裂是致密储层改造的重要手段,在致密砂岩、碳酸盐岩、火山岩、页岩、煤层等储层连通性改造中广泛使用。对压裂效果的评估以及对裂隙的空间描述,是编制开发方案、提高产能的关键环节。微地震监测技术是目前比较有效、可靠性高的一种压裂裂缝监测及储集体空间描述技术,能够实时监测压裂裂缝的空间展布,被国内外广泛应用于压裂裂缝监测和油藏动态监测。本文分析了非常规油气微地震监测技术的需求、国内外(包括中国石油集团)微地震监测技术现状及微地震监测技术面临的挑战,指出了中国石油集团非常规领域微地震监测技术的发展方向。
Hydrofracture and acid fracturing are major approaches for tight reservoir reformation in tight sand,carbonate,volcanic,shale,and coalbed to improve pay zone connectivity.It is kernel link to evaluate fracturing results and describe fracture spatial extension in order to draw up development scheme and enhance production.Recently microseismic becomes an effective and reliable technology for dynamic fracturing monitoring,reservoir body description and fracture spatial distribution description.This article analyzes microseismic application status and technical requirements in these fields.Authors discuss also challenges and the development direction of microseismic for CNPC unconventional resource exploration and production.
