Abstract
Nowadays, the steam conformance analysis and vapor-liquid interface (liquid pool level) of the typical horizontal well in SAGD operation is relatively mature. With the advancement of technology, some of multi-lateral horizontal wells engage in SAGD operation. However, steam conformance and liquid pool description, especially the lateral section is still one of the main difficulties. In this study, based on the modification of steam conformance formula, the judgment method of main horizontal and different types of multi-lateral wells is established. Meanwhile, the liquid pool of different types of multi-lateral wells is characterized by using the steam conformance. The research will provide technical support for the production improvement in multi-lateral horizontal wells in SAGD operation.
