Zusammenfassung:	The utility model discloses a well drilling pressure device, including the pressure block, be provided with the balancing weight on the pressure block, be provided with the drilling fluid runner the same with being connected the drilling string internal diameter in the pressure block. An increasing or reduce, the structure is simpler, and convenient to use can effectually in shallow layer, the big displacement horizontal well drilling process of super shallow layer apply the weight on bit to the shaft bottom drill bit, reduces the construction operation risk that well drilling pressure device can carry out the balancing weight according to required weight.
