China oil network news January 25th morning, the temperature of minus 25 degrees Celsius, Liaohe Oilfield Block Du 84 SAGD flooding project construction site, several construction workers of the eyebrows and beard hanging on the white ice. A manager at the site said that the completion of the well network has been completed at present. 　　The Liaohe oil field, which accounts for more than half of the heavy oil production, was 26 thousand and 82 tons on the day of January 25th, firmly grasped within the scope of the plan. 　　Heavy oil is "afraid of cold". In the case of minus more than 20 degrees Celsius, the heavy oil in Liaohe Oilfield has become a "solid". Thermal recovery is the basic mode of production of heavy oil, steam, oil and gas transportation, construction and other aspects of the production process of heavy oil by low temperature test, prone to wells effectively shorten the production cycle, resulting in the operation cost of oil production increased, yield problems of different degrees of decline. Winter production has always been the "test period" of heavy oil production in Liaohe Oilfield. 　　Aiming at the problem of the development of 40 years of winter heat preservation facilities aging, more projects, the implementation of high standards of Liaohe Oilfield winter heat preservation and winter production work, highlighting the development of fire flooding development mode and important oil blocks and other key projects, find the weak links, to develop new measures, make arrangements in advance, to ensure that oil and gas production units planned winter heat preservation and measure, time and responsibility, to achieve a "no dead". 　　After the arrival of strong cold wave in January 22nd, Liaohe Oilfield proposed "no frost damage to a device or an inch of pipeline, no freezing injury to one employee, no safety accident". Process for the heavy oil of Liaohe Oilfield using a number of "warm": the steam pipeline insulation surface, reduce the heat loss of steam injection boiler; steam dryness; vacuum insulated pipe column, annulus filled with nitrogen heat insulation; group type steam injection, with the same production, avoid steam channeling, improve the utilization of steam injection rate; using separated zone injection, improve the vertical extent of the use of the steam absorption profile uniform, improve heat utilization rate. At all levels, cadres at the various levels have organized the work of low temperature resistance in the field, strengthened the maintenance of thermal insulation and adjusted the thermal power operation to ensure that the thermal efficiency of the oil well facilities is not reduced. 　　Relevant content:OGEM petroleum solid control equipment has always been the credibility and quality as the cornerstone of development, in the staff of the full implementation of "unity, innovation, truth-seeking, integrity" business purposes.
