Abstract:The steam injection thermal recovery technology has often been applied to the exploitation of heavy oil. In actual production, the heat dissipation loss is serious because the steam injection pipelines are very long and in the open air. This has greatly influenced the benefit of oilfield exploitation. Optimizing thermal insulation materials and thermal insulation structures can effectively reduce heat dissipation loss, but the calculation of related data is very complicated. To improve the efficiency of information collection and processing and to increase the speed and accuracy of the calculation, this study introduces information technology to the analysis project of the thermal insulation benefit of heavy-oil steam-injection pipelines. Through constructing an evaluation model of the thermal insulation benefit of heavy-oil steam-injection pipelines, we identify the main parameters affecting the evaluation of the thermal insulation benefit and build an evaluation system of the thermal insulation benefit of heavy-oil steam-injection pipelines. This system can automatically calculate heat loss and carry out visual analyses according to the actual operating environment and loading condition of a steam injection pipeline. At present, this system has been applied in the Xinjiang Oilfield. The calculation results of the system can benefit the accurate and fast optimization of thermal insulation materials and thermal insulation structures, thereby effectively improving the benefit of oilfield exploitation.
