The Research on the Super Heavy Oil Reservoir Characteristics of Du 84 Block in Liaohe Oilfield

摘要

The reservoir characteristics of super heavy oil directly determine the development effects of heavy oil thermal recovery. The development process of super heavy oil reservoir in Du 84 block contains the production test of steam huff and puff-the industrialization of steam huff and puff-the production test of SAGD-the industrialization of SAGD. The researches on the reservoir characteristics carried out at the early stage of the reservoir development have partly guiding significance for the reservoir development and deployment. As the development progress, we need describe the reservoir characteristics of super heavy oil once more in order to guide the deployment of thermal well network. This article makes a detailed and reliable description of reservoir characteristics of super heavy oil and provides fundamental data support for the next dynamic regulation by doing a statistical analysis of the characteristics of sand body distribution, petrology, physical property and aeolotropy of the Guantao formation and the Xinglongtai reservoir [1,2] .
