储层压裂微地震的3种监测方式
Three Kinds of Arrangements Monitoring Micro-seismic Events Induced by Reservoir Fracturing
【摘要】 储层压裂在油气田的开发中具有很重要的作用,是低渗透油气藏实现高产稳产的重要手段。压裂产生的微地震可提供裂缝扩展过程的重要信息,准确监测微地震对于评价压裂效果具有很重要的意义。介绍检测压裂微地震的3种主要监测方式:地面监测方式、井下监测方式和井口监测方式。阐述3种监测方式中传感器的布置特点,分析了计算微地震源位置的走时方程,讨论了3种监测方式的优势和缺点,最后对微地震监测的现场实践提出了一些有益的建议。
【Abstract】 The reservoir fracturing technique played an important role in oil and gas development,which was valuable to improve the oil production in low permeability reservoirs.The induced micro-seismic events provided some important data for the expanding process of fracturing,it was helpful for evaluating the results of reservoir fracturing.At present there are three kinds of arrangements monitoring micro-seismic events including surface monitor arrangement,down-hole monitor arrangement and well-head monitor arrangement,the characteristics of the arrangements are also described.The seismic waves travel-time equations are analyzed for solving the positions of micro-seismic sources and discussing the predominance and shortcoming of the arrangements.Suggestions are provided for field application of the monitoring micro-seismic events.
【Key words】 reservoir fracturing; monitoring micro-seismic events; sensor arrangement; travel-time equation; seismic source position;
