Study On The Infiltrating Fluid Regular Pattern Of Heavy Oil Steam Stimulation And Deep Catalytic Cracking Process For Near Wellbore Area

The traditional technique of heavy oil exploitation is extract oil by steam injection.But the technique that aquathermolysis under steam injection conditions, injects aquathermolysis catalyst system when steam injection,and let heavy oil act a series of chemical reaction, then reduces the viscosity inconvertiblly and upgrades the heavy oil in layer and enhanced oil recovery, have great latent value. So in order to make the technique much more effective for enhanced oil recovery, we must study on the infiltrating fluid regular pattern of steam injection deep catalytic process. Therefore, this paper inherits the previous research results, combined with the concrete situation of Gudong production factory in Shengli oil field,first,calculate the temperature site of heavy oil steam stimulation and deep catalytic cracking process according to Lauwerier means, and draw the curve drawing of temperature and well diameter. Secondly,researchs on the aquathermolysis catalyst’s visbreaking effect and the changing rule of visbreaking flowage property. Once more build the steam stimulated well fluids rate forecast pattern,and calculate three wells concretly.Last, utilizing the language of C#,program the heavy oil steam stimulation deep catalytic cracking fluids rate forecast pattern software.Strengthen the recognition of the infiltrating fluid regular pattern of heavy oil steam stimulation and deep catalytic cracking process for near wellbore area.
