技术开发单位中国电子科技集团公司第二十三研究所技术简介目前,国内大部分油田已经进入低品位非常规油气藏勘探开发阶段,需要采用压裂施工方式,而压裂裂缝监测急需微地震监测技术和产品。微地震监测需要使用高灵敏度的检波器,常规检波器无法满足要求,而国外高灵敏度检波器引进费用极高。该光纤地震检波系统以光纤地震检波器技术为主体,与传统电子检波器技术相比,由于其井下传感器不含电子
At present, most domestic oilfields have entered the stage of exploration and development of low-grade unconventional oil and gas reservoirs, and require the use of fracturing construction methods, and the monitoring of fracturing cracks is in urgent need of micro-seismic monitoring Technology and products. Micro-seismic monitoring requires the use of high-sensitivity detector, the conventional detector can not meet the requirements, while the introduction of foreign high-sensitivity detector costly. The fiber optic seismic detection system to fiber optic geophone technology as the main body, compared with the traditional electronic geophone technology, because of its underground sensor does not contain electrons
