摘要
区块监测技术主要包括注汽井监测、生产井监测、观察井监测和远程油井测控系统4大部分。SAGD开发对油藏监测系统的要求与蒸汽吞吐有所不同。2005年2月以来,通过监测技术在杜84块馆陶和兴Ⅵ先导试验区的应用,认清了蒸汽腔的展布、温度和压力在平面和纵向的分布、水平段的动用状况,指导了SAGD注采参数的调整、注汽井的选择及单井注汽量的分配,为SAGD先导试验的成功提供了保障。
Block surveillance mainly involves surveillances on steam injectors, producers, observers and remote producers. Reservoir surveillance system of SAGD development is different from cyclic steam stimulation. Since February 2005, the surveillance technique has been used in pilot sites of Guantao and Xing VI in Block Du 84 with clear understanding of steam chamber distribution, lateral and vertical distribution of temperature and pressure, producing status in horizontal segment, and guided modification of SAGD parameters, injector selection and single well steam injection allocation, thus providing guarantee for successful SAGD pilot test.
