| description | The invention provides a throwing-in and pulling downhole foam generator which mainly solves the problem that the quality of oil-dispersing foams cannot be guaranteed due to the fact that the poor foaming quality exists universally in the current foam flooding ground foaming and defoaming is serious during the foaming injection operation. The throwing-in and pulling downhole foam generator is characterized in that the throwing-in and pulling downhole foam generator comprises a matching oil pipe and a throwing-in and pulling foaming core body; the matching oil pipe comprises a clamping and fixing pipe, a connecting pipe, an adapting pipe and a one-way valve, and the throwing-in and pulling foaming core body comprises a throwing-in and pulling and back-moving prevention structure and a foam generating structure; the foaming core body is assembled inside the matching oil pipe to realize throwing-in and pulling and clamping and fixing; when the foam injection operation is performed, gas is injected through the oi |
