【摘要】 研制了1套以三分量MEMS检波器为核心硬件的微地震监测系统,并结合GPS系统对监测过程进行精确授时。同时编制数据化记录和处理软件,实现网络化自动监测功能;通过开发计算机判别标准和实时定位理论系统,对数据和微震源进行自动化处理和计算。利用该系统对东辛油田营11进行了6个月现场注水微震监测,对监测数据的处理表明营11注水区域裂缝发育方向基本上为NE90°-NE125°,与地应力裂缝模拟结果相符较好,两者结合给出了这个地区合理开发部署建议。更多还原

【Abstract】 Independent micro-seismic monitoring systems called MEMS had been developed in this paper.The systems were composed of three components MEMS geophone which was the core hardware,and with GPS system for doing real-time locating and time service.While,the digital recording and data processing software according with the hardware systems had been compiled and had been realized automatic network monitoring function.Otherwise,the system of computer discriminatory standard and real-time locating concept had been developed and automatic data processing and seismic locating could be calculated at the same time.After a six-month injection site micro-seismic monitoring Using the systems on Ying 11 block of Dongxin field and collecting abundant micro-seismic wave files,the monitoring date processing showed that the orientation of injecting fracture was mainly NE90° to NE125°,in line with the stress simulation results well,given a combination recommend of this region rational development.更多还原
