The film seat (2) is fixed in the work cavity (1-2), The inner of the film seat (2) sets small diameter hole (2-1), major diameter hole (2-2) and the middle diameter hole (2-3) which is interlinked with crude oil cavity (1-1), all of them link up mutually, the isolation film (3) is installed in the major diameter hole (2-2), one end of spring tube (5) is installed in the seat through-hole (2-4) of the film seat, the other end is installed in the side wall of the connecting rod (6) and links the inner axial hole (6-1) of the connecting rod (6), the other end of the connecting rod (6) is welded with one end of the iron cores (7), the iron core (7) has coil (9) and linear bearing (8) in it , seating (11) is set on the coil (9) and linear bearing (8), the upper end of the outer covering (1) fixes the connecting axle (10). Since that device does not have any electronic component, even if the star counts of the straight line electric motor of the displacement oil pump is imbalance, the testing instrument will not be breakdown by the high-voltage, and it may take out the pressure of the pump in the pit at any time.
Description
Technical field
The present invention relates to a kind of pressure tester, be specifically related to a kind of testing pressure down hole device that is installed under the reciprocating type oil-immersed pump.
Background technology
PRESSURE DATA is dynamically very important to the production of analyzing and grasp oil field subsurface picture and oil well, must get entirely, get the efficient operation that accurate these data could guarantee oil well.Because the external diameter of reciprocating type oil-immersed pump surpasses 90mm and there is electricity cable the oil pipe outside, adopt conventional pumping unit well eccentric testing technology can't realize testing pressure down hole.Because can produce high vibration during the work of the linear electric motors on the reciprocating type oil-immersed pump, and motor asterism imbalance, adopt present electric pump well down-hole electronic pressare-measuring technology, exist the tester electronic component to be broken down by high-voltage easily, can't satisfy the problem of pressure measurement requirement.
Summary of the invention
The purpose of this invention is to provide a kind of testing pressure down hole device, the conventionally test technology that can solve this device can't satisfy reciprocating type oil-immersed pump well pressure problems of monitoring and electric pump well down-hole electronic pressare-measuring technology, exist the tester electronic component to be broken down by high-voltage easily, can't satisfy the problem of pressure measurement requirement.
The present invention includes shell; The present invention also comprises film seat, barrier film, support, turn tube, connecting rod, iron core, linear bearing, coil, connecting axle and cover for seat; Shell is made up of former oil pocket and working chamber, the sidewall of former oil pocket is provided with oilhole, the film seat fixedly is housed in the working chamber, be provided with the small diameter bore of mutual perforation in the film seat from top to bottom successively, large diameter hole and the middle diametric hole that communicates with former oil pocket, the outward flange of barrier film is contained on the inwall of large diameter hole, one end of turn tube is installed in the through hole on the film seat sidewall, small diameter bore communicates with the inner chamber of turn tube, the other end of turn tube is installed on the sidewall of connecting rod, the inner chamber of turn tube communicates with the interior axial hole of connecting rod, the one end welding of the other end of connecting rod and iron core, coil and linear bearing from top to bottom are housed on the iron core successively, cover for seat be contained on the coil and linear bearing on, support be contained in the working chamber and respectively with shell and cover for seat welding, fixedly connected with connecting axle in the upper end of shell.
The present invention has following beneficial effect: one, the present invention is a kind of testing pressure down hole device that is applied on the reciprocating type oil-immersed pump, it can solve the conventionally test technology can't satisfy reciprocating type oil-immersed pump well pressure problems of monitoring and electric pump well down-hole electronic pressare-measuring technology, can't satisfy the problem of pressure measurement requirement.During use, this testing pressure down hole device is received on the linear electric motors of reciprocating type oil-immersed pump lower end, the small diameter bore of barrier film epicoele, large diameter hole, turn tube and connecting rod inner chamber all are full of fluid, by the fluid conducting pressure.When the oil pressure in the former oil pocket during greater than the oil pressure in the turn tube, pressure in the former oil pocket passes in the turn tube by barrier film, the turn tube drives the iron core action in the coil, after being changed, winding inductance quantity is transferred to ground by power cable, record inductance value at well head with the inductance measurement instrument, relation curve by inductance and pressure checks in pairing force value again, and this force value then is bottom pressure this moment.Two, the present invention has simple in structurely, safe and reliable, owing to do not adopt electronic component, even the linear electric motors asterism imbalance on the reciprocating type oil-immersed pump, tester can not be broken down by high-voltage, and can take out the advantage of down-hole pump downforce at any time.
