| Steam thermal recovery is the dominant technology of the heavy oil recovery. There have been varying degrees heat loss in steaming system production run, gas production ,transportation, steaming huff and puff etc. The statistics of oil field production indicates that the dryness fraction of the steam heat boiler export is about 75% at present .While the dryness fraction of steam of the steamed well mouth is only about 60%, which affects the effect of steam huff and puff and the economy of thermal production.Steam pipe line as one of the main facilities which is used in the steam line system of the thermal production ,the main reason for the decline of well head steam quality, the key factor of the decreasing energy efficiency .In order to make the right evaluation of the state which is the consumption consume of the steam line system, we make an test of the heat loss of the steam line network. And we also probe into the heat loss of the steam line system and the factors.In order to solve the heat inefficency of the steam line system, we look into the present situation of the steam line network and the state of heat preservation. Then we found the open questions and the weak points of heat preservation. We make the evaluation and affirm the reason of the heat inefficency of the system.We adopted the combination of bench test and engineering optimization, then we screened out high-quality adiabator, and designed the best heating composition. We designed and developed the software"The analysis and optimization of energy of the steam line system in thermal production"It can offer convenience to the computational analysis of heat loss of the steam line system. It can also be used for design calculation and experimental verification of steam pipeline feasible radial-radius, so it can offer technical support for the reduce of heat loss of the system, the raise of well head steam quality and the raise of heat efficicency of the steam injection system.
