枣35断块裂缝型稠油油藏蒸汽吞吐技术研究与试验

Study and Test for Take in and Send Out in Large Quantities Tech of Steam in Dense Oil Reservoir with Crack Model in Zao35 Fault Block.

枣35断块为大港油田典型稠油开发区块,在衰竭和注水开发后,采出程度很低。精细油藏描述与调整挖潜技术研究表明,开采基质中原油最有效的方式是蒸汽吞吐。通过对裂缝型稠油油藏蒸汽吞吐工艺技术研究,形成了裂缝型火成岩热采配套工艺技术,成功开展了2口井现场试验,见到了显著效果。

Zao35 fault block in Dagang oilfield is a type of dense oil exploitation district. By studying tech of fine description of reservoir and regulating for digging potential on condition of low producing degree at time of shortage of reservoir power and after water injection for oilfield exploitation, it shows that take in and send out in large quantities tech of steam is an effective way to exploit crude oil in radix rock. A set of matching tech of thermal recovery for igneous rock of crack model has been formed and an obvious result has been gained in two wells of applications.
