The general configuration of wellhead injection device, ram BOP, annular BOP combination was improved to improve the efficiency of horizontal well modified multilayer fracturing operation. In order to meet the needs of high duty injection, drag under pressure, adjusting the position of drilling rigs, reducing the blowout time, and reducing the height of wellhead combination, a kind of injection and preventer equipment were developed which can be used for stripping. The design of this kind of equipment is reasonable, the structure is compact, and it is safe and reliable, the operation of it is easy, and the construction efficiency is improved.
