本文简要介绍了美国EES公司生产制造的井下蒸汽发生器装置。它与常规蒸汽发生器的不同之处在于它可将蒸汽和惰性气体一同直接注入油层，降低原油粘度，减少热量损失，防止环境污染。文中还系统、具体地介绍了井下蒸汽发生器的工艺配套设备、结构、二作原理。从攻远看．通过局部工艺技术的改进和完善，在超深井、低渗透油藏和近海油藏的井中推广应用是有吸引力的，目前国队已有较多的油田使用它进行稠油开发。

This article briefly introduces the downhole steam generator unit manufactured by EES of the United States. It differs from a conventional steam generator in that it injects steam and inert gas directly into the reservoir, reducing the viscosity of the crude oil, reducing heat loss and preventing environmental pollution. The article also systematically and specifically introduced the underground steam generator process supporting equipment, structure, two for the principle. Look from the attack. Through the improvement and improvement of partial process technology, it is attractive to popularize and apply wells in ultra-deep wells, low-permeability reservoirs and offshore reservoirs. At present, the country’s oil field has more oil fields used for heavy oil development.
