control method and device for wellhead spraying system in oil field operation

The invention discloses a control method and device for a wellhead spraying system in oil field operation. The method comprises the steps that a request instruction is received, and the request instruction is used for requesting for well mouth spraying making operation; in response to the request instruction, the first waterway is controlled to be conducted, so that a water source in the water storage container flows out of the water storage container and is conveyed to a wellhead through the first waterway; and when the water source in the first waterway forms a blowout mode at the wellhead, blowout prevention equipment for controlling the wellhead is arranged so as to convert the blowout mode into a non-blowout mode by utilizing the blowout prevention equipment. According to the control method and device, the technical problem that potential safety hazards exist in oil field wellhead simulation drilling operation in the prior art is solved. 本发明公开了一种油田作业中的井口造喷系统的控制方法及装置。其中，该方法包括：接收请求指令，其中，请求指令用于请求进行井口造喷作业；响应
