Improved imagine for down hole low-concentrating flowmeter
Keywords:
Development, ExperimentAbstract
For completing the test of wells with high, medium and low production, avoiding from flow-concentrating pressure difference and up push appeared at collector of bore hole fluid to produce a confine for the upper measuring limitation of down hole flow-concentrating flowmeter. The paper suggests a plan that using one down hole flow-concentrating flowmeter down and up once time in the oil well to finish test for different produced layers and integrate full and part down hole flow-concentrating flowmeter to make every flow-meter have feature of full and part flow-concentrating. The new flowmeter has the characteristics of low floor level, extensive testing scope, automatic distributary and stable testing point.
