【摘要】 水力压裂技术作为非常规油气藏开发的主要技术手段已在油气生产中广泛应用,微地震监测技术是水力压裂过程中压裂缝评价的一种有效手段。介绍了微地震监测技术的原理及该技术在国内外的发展历程,叙述了微震事件的定位方法;评述了2种非常规油气层压裂微地震监测方法,即井中监测技术和地面监测技术,并对其原理、特点和发展进行了阐述和对比,最后论述了微地震监测技术的发展方向。更多还原

【Abstract】 Hydraulic fracturing technology has been widely used in oil and gas production as the main technical means of unconventional reservoir development. Micro-seismic monitoring technology is an effective means of fracture evaluation in hydraulic fracturing process.The principle of microseismic monitoring technology and its development at home and abroad were introduced,and the location method of microseismic events was described. Two kinds of unconventional reservoir fracturing microseismic monitoring methods,in-well monitoring technology and surface monitoring technology which were reviewed. Their principles,characteristics and development were described and compared. Finally,the development direction of microseismic monitoring technology was discussed.更多还原
