在冬季寒冷气候条件下，野外工程机械发动机每天早晨首次启动都存在启动困难的问题，而在可控震源上这个问题表现得更为严重，尤其是震源刚刚运到工区开下平板车前启动时。因此，多年来可控震源冬季启动保温问题，一直困扰着现场震源应用。本文分析了可控震源启动及系统保温困难的原因，并提出了相应的改进措施。综合应用这些措施，可以改善震源发动机启动和预热、保温性能，使可控震源在寒冷气候下能快速启动和升温、保温，以保障勘探作业的高效率和施工质量，延长震源使用寿命。

In very cold season, diesel engines on all engineering machinery stored in the field have difficulty in initial starting every morning. For the vibroseis, this problem becomes more serious. Whenever the vibrators are delivered to the cold areas, it needed at least three or four hours to start the engine. During field operation, it also needed very long time to warm up the engine and the hydraulic system. Most of the time, the engine and hydraulic system will operate in low temperature which is very harmful to the engine and hydraulic system. So, the problems of the engine start and the system warm up have been disturbing the normal operation in cold regions for years. In this article these problem are analyzed in detail and the authors provide several ways to solve them. Integrating application of these methods can assist the vibrator starting quickly and instantly warming up. Also these methods can keep the engine and hydraulic system working in normal temperature or even in extremely cold weather. So we can get benefits of long life of vibrators, furthermore high efficiency and high quality of geophysical exploration can be achieved.
