摘　　要：相比传统微地震、示踪剂等压裂监测技术,分布式光纤具有同步跟踪压裂施工过程的实时性,可根据压裂异常情况及时调整压裂施工参数,提高压裂价值。通过系统描述J11-Z1井分布式光纤DAS在临井压裂监测中的响应特征,并与微地震、产剖测试进行对比,结果显示一致性强,验证了分布式光纤DAS在水平井临井压裂监测领域的可行性,该项技术具有很好的推广价值。Compared with traditional fracturing monitoring technologies such as microseismic and tracer agents,distributed fiber optics offer real-time monitoring with synchronized tracking of the fracturing process.This enables timely adjustments to fracturing parameters based on abnormal fracturing conditions,thus enhancing fracturing effectiveness.This paper describes the response characteristics of the distributed fiber optic DAS in fracturing monitoring of offset wells at Well J11-Z1,and compares the results with microseismic and production profile tests.The findings show strong consistency,validating the feasibility of distributed fiber optic DAS for fracturing monitoring in horizontal well offset well applications.This technology has significant potential for widespread use.
