An Erosion On-Site Test Device for Equal Flow Type Multi-stage Velocity Mixed Transport Pipeline Erosion

Abstract

The invention relates to the technical field of erosion corrosion protection of an oil-gas mixture transportation pipeline, in particular to an equal-flow multilevel flow rate mixture transportation pipeline erosion field test apparatus. The test apparatus comprises an oil-gas well, wherein a wellhead of the oil-gas well is connected with one end of a collection and transportation pipeline, and the other end of the collection and transportation pipeline is connected with an established oil-gas well yield measuring apparatus; one end of a Q-flow equal-caliber test pipe section is connected withan inlet pipeline, and the other end is connected with a 1 / 2Q flow equal-caliber equal-length constant-flow-rate test pipe section by virtue of a primary distribution point; and the other end of the1 / 2Q flow equal-caliber equal-length constant-flow-rate test pipe section A is connected onto a secondary distribution point by virtue of a plurality of straight-pipe-section test member and an elbowtest member and separately connected with one end of a 1 / 4Q flow equal-caliber equal-length constant-flow test pipeline B and one end of a 1 / 4Q flow equal-caliber equal-length constant-flow-rate testpipe section D by virtue of the secondary distribution point. The test apparatus provided by the invention has the advantages of simple structure, convenience in operation and management, safety and reliability in operation, low investment and the like.

Description

technical field [0001] The invention relates to the technical field of erosion and corrosion protection for oil and gas mixed transportation pipelines in oil and gas fields, in particular to an equal flow type multistage flow velocity mixed transportation pipeline erosion field test device. Background technique [0002] At present, in my country, the research on the erosion mechanism and protection technology of oil and gas mixed transportation pipelines in oil and gas fields mainly adopts the method of indoor instrument test. The test medium conditions and operating conditions are very different from those of the production site, and the test results obtained from this are difficult to accurately determine Reflecting the actual situation, this field has not achieved substantial technological progress for many years. The technical measures to solve the erosion protection problem of oil and gas mixed transportation pipelines in oil and gas fields in engineering practice are li...
