The utility model belongs to the technical field of petroleum drilling and production equipment, and particularly relates to an injection head for a coiled tubing operation machine. The injection head comprises an injection head main body, an injection head integrated valve group and an execution element controlled by hydraulic transmission are arranged on the injection head main body, the injection head integrated valve group is connected with the execution element through a hydraulic pipeline, and the injection head integrated valve group is used for controlling the execution element to act. The injection head integrated valve group is arranged on the injection head main body, so that the distance between the injection head execution element and the injection head integrated valve group can be greatly shortened, and a hydraulic pipeline can be greatly simplified; meanwhile, the response time of the injection head execution element can be greatly shortened; besides, the execution element is controlled throug
