description The utility model relates to the field of gas extraction drilling gas spraying prevention structures, in particular to a directional drilling site gas spraying prevention gas storage system which comprises a sealing box body, a slag inlet and a slag outlet are formed in the sealing box body, a coal slag flowing pipe is arranged between the slag inlet and the slag outlet in the sealing box body, and a gas outlet is formed in the sealing box body. The slag inlet end of the coal slag flowing pipe in the sealed box body is higher than the slag outlet end, the top of the coal slag flowing pipe is provided with a gas outlet hole, and the top of the sealed box body is provided with at least one negative pressure pipe connector. The directional drilling site gas blowout prevention gas storage system is low in manufacturing cost, easy to install and easier and more convenient to machine and maintain. After the device is put into use, zero-overrun prevention occurs in kilometer drill site gas, and the construction prog
