The steam chamber is expanding at present, and daily oil producti.
通过2a的现场应用,馆陶油层SAGD试验获得成功,目前处在蒸汽腔扩展阶段,井组日产油较蒸汽吞吐阶段上升了72t,预测SAGD开发可提高采收率27%。
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 .
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。
If the corresponding oil reservoir simulation software can be developed, the dynamic changes for the size and shape of steam compartment during horizontal SAG flooding can be predicted, and the effect of capillary force, steam dryness and forma.
如果能研制相应的油藏模拟软件,可预测水平井蒸汽辅助重力驱蒸汽腔室的大小及形状的动态变化,模拟计算毛管力、蒸汽干度、地层深度等对蒸汽腔室发育程度的影响。
