Problems solved by technology
[0006] (2) It takes a long time to occupy the drilling rig. After the drilling construction is completed, the drilling rig cannot carry out other drilling construction. As special equipment for drilling, it is used as auxiliary equipment during the construction process of carbon dioxide phase change fracturing, resulting in a certain waste of resources, resulting in slow construction progress and high economic costs, which limits the popularization and application of this technology to a certain extent;
[0007] (3) Affected by the push tool, it is difficult to realize multi-hole simultaneous fracturing during the construction process of carbon dioxide phase change fracturing, which affects the field application effect of this technology to a certain extent

The invention discloses a liquid carbon dioxide phase change splitter deep hole pushing device. Holding mechanisms is fixed to the front end and the rear end of a frame body support beam, the middle of the frame body support beam is provided with a transfer mechanism with the same structure of the holding mechanisms by a sliding bar in sliding mode, one end of the transfer mechanism is provided with a hydraulic jack as a driving device, and a pneumatic liquid booster pump, a hydraulic oil tank and a high pressure oil control system are arranged, so that the pneumatic liquid booster pump is driven by the power of down hole pressure wind, and the holding mechanisms, the transfer mechanism and the hydraulic jack are supplied with oil by the pneumatic liquid booster pump and the high pressure oil control system; and thus the liquid carbon dioxide phase change splitter deep hole pushing device which is easy to use and high in efficiency is provided by the down hole pressure wind and a hydraulic system, and the liquid carbon dioxide phase change splitter deep hole pushing device has the characteristics that the concept is ingenious, the use is convenient, and the transforming is easy.
Description
technical field [0001] The invention relates to a deep hole pushing device for a liquid carbon dioxide phase change cracker, specifically, it is mainly used for deep hole pushing of a liquid carbon dioxide phase change cracker. Background technique [0002] At present, the liquid carbon dioxide phase change cracker is a new type of blasting device based on the liquid carbon dioxide phase change and expansion to release energy. It is widely used in boiler unblocking, building demolition, and blasting operations in special areas abroad. , New Zealand and other countries' safety certification, it is a blasting technology with advanced concept, safe method and remarkable effect in the world. In recent years, relevant scientific research units in my country have introduced this technology into the field of coal mining. On the one hand, it is used to meet the needs of mine blasting engineering, and on the other hand, it is also a set of effective and safe coal seam gas enhancement...
