Geothermal well pressure measuring system suitable for pneumatic down-the-hole hammer drilling

The geothermal well pressure measuring system comprises an outer cylinder, an inner cylinder, a measuring mechanism and a damping mechanism, and an outer detection hole is formed in the side wall of the outer cylinder; an inner detection hole is formed in the side wall of the inner cylinder, the inner cylinder is coaxially arranged in the outer cylinder, and an annular space is formed between the outer cylinder and the inner cylinder; the measuring mechanism is arranged in the annular space and measures the inner and outer annular pressure through the outer detection hole and the inner detection hole. The vibration reduction mechanisms are arranged in the annular space, the number of the vibration reduction mechanisms is two, and the two vibration reduction mechanisms are connected to the two ends of the measuring mechanism respectively. The vibration of the measuring mechanism can be effectively suppressed. 本申请涉及一种适用于气动潜孔锤钻井的地热井压力测量系统，包括：外筒、内筒、测量机构和减振机构，所述外筒的侧壁上设有外检测孔；所述内筒的侧壁上设有内检测孔，且所述内筒同轴设于所述外筒内，所述外筒与所述内筒之
