Project Design for Heavy Oil Displacement by In-Situ Combustion in Zheng-408 Block, Dongying Sag

Based on the criteria of selection and evaluation at home and abroad, integrated with the physical simulation experiments, the reservoir geological conditions in Zheng-408 Block of Dongying sag are selected and evaluated, and the feasibility of thermal sensitive heavy oil reservoir stimulated by in-situ combustion is demonstrated, followed by the main factor analysis about affecting the process of in-situ combustion and the determination of the best well block for in-situ combustion pilot test according to the physical simulation results and the experiences at home and abroad. Also, in view of the characteristics of thermal sensitive heavy oil reservoir, the optimization of project design and main parameters for heavy oil displacement by in-situ combustion are made. The field implementation and good effectiveness can be as a guide for reference to the development of the same kinds of reservoirs.
