Abstract

The invention provides a performance test method and a performance test device of a high-power fracturing pump truck. The method comprises the following steps that 1, preparatory work before a test is performed; 2, a fluid feed test is performed; 3, discharge pressure P and displacement Q0 after pressure reduction of the fracturing pump truck are recorded; and 4, output power of the high-power fracturing pump truck is calculated. A water tank of the device is connected with a fluid feed centrifugal pump and a fluid feed butterfly valve; the fluid feed centrifugal pump is connected with a fluid feed motor, a circulation fluid butterfly valve and a test fluid butterfly valve respectively; a suction inlet and a discharge outlet of the high-power fracturing pump truck are communicated with the test fluid butterfly valve and a high-pressure cross joint; the other three connectors of the high-pressure cross joint are connected with a martin decker gauge, a safety valve and a needle valve respectively; the needle valve is in shaft connection with a pressure control motor; a plug valve, a throttling valve, a pressure reducer, a flowmeter and a metering fluid butterfly valve are connected in series at one end of the needle valve sequentially; and the other end of the metering fluid butterfly valve is communicated with the water tank by a pipeline.

Description

technical field [0001] The invention relates to the field of oil and gas field construction pump trucks, in particular to a performance test method and a test device for a high-power fracturing pump truck. Background technique [0002] In the process of oil and gas field development, in order to improve the recovery rate of oil and gas reservoirs, it is necessary to perform fracturing operations on the reservoir. The fracturing pump truck is the main equipment for fracturing operations. With the increase in the number of deep and ultra-deep wells, the fracturing pump truck The power is gradually increased. At present, the finalization of the high-power fracturing pump truck is calibrated by the power of the fracturing pump. The power of the fracturing pump has been determined according to the theoretical volumetric efficiency and mechanical efficiency at the factory. When carrying out the performance test of the fracturing pump truck It is only to carry out performance tes...
