Negative pressure plugging removal method and device for oilfield layering pressure and liquid production profile test

The invention discloses a layered oil well pressure and liquid production profile test negative pressure plugging method and apparatus, method of testing, including the normal production period by suction pressure pressure sealing up, measuring pressure and stratified liquid production profile and tube monitoring, working condition of negative pressure blocking column five steps, a work device includes; pump tubing and sucker rod, the external oil pressure control, differential pressure type packer, plug, ground pumping equipment; comprises three sets of new device: test pump, sealing up the piston tubing, manometric tube. Different depth, different fluid volume, different pressure and different number of layers with different size and the number of wells tools; advantages make production, pressure test, stratified fluid profile testing, negative pressure blocking functions in one, can solve the existing layered oil well pressure and fluid profile testing and stimulation measures combining technology widespread job number, complex operation, expensive tools, the reliability is not high, can not be widely applied problem.
