Technical Field

the invention relates to the field of petroleum exploitation fracturing equipment, in particular to a novel pressure relief and water drainage device for a manifold of a diesel pump unit.

Background

in the process of exploiting the oil and gas field, the fracturing technology is one of important technical means for increasing storage and increasing production of the oil and gas field, and the fracturing operation is carried out on the oil and gas well, so that the permeability of an oil and gas layer can be enhanced, the flowing environment of oil and gas at the bottom of the well is improved, and the purpose of improving the yield of the oil and gas is achieved. In the fracturing operation process, the performance of the fracturing equipment directly determines the fracturing effect of an oil-gas well and the increase of the oil-gas yield. At present, fracturing equipment mainly comprises a fracturing pump truck, a sand mixer truck, an instrument truck, a high-pressure manifold and related fracturing auxiliary equipment. The diesel oil water pump unit is a fracturing auxiliary device and mainly provides a power lifting device for water for fracturing operation of oil and gas fields.

At present, a diesel water pump unit commonly used in domestic fracturing operation sites mainly comprises a diesel engine, a water pump, a manifold and other parts. In order to meet the requirements of fracturing operation, the whole unit generally adopts a structure of one unit for one unit, two water pump outlets for one unit and one unit for one unit are connected to one unit to form a manifold structure together with an inlet and outlet pipeline, and the water flow direction is controlled by a check valve or other methods. However, the water flow direction of the diesel water pump unit common in the market is single, and reverse drainage cannot be realized. The residual water in the reservoir and the manifold is not properly treated to cause environmental pollution, or the water cannot be discharged in time when the pipeline is blocked due to overlarge pipeline pressure in the production process to cause damage to the manifold, and a safety accident occurs in serious cases.
