Embodiment Construction
[0012] Such as figure 1 As shown, the present invention provides a structure of oil and gas well exploratory well hydraulic slotting test process string, including oil pipe 4, power component 8, cutter and ball seat nozzle 11, pump seat 12, positioning nipple 5, packer 6 with centralizer7.
[0013] Wherein, the power unit 8 , the cutter and the ball seat nozzle 11 are sequentially assembled on the bottom end surface of the oil pipe 4 .
[0014] The pump base 12, the positioning nipple 5, the packer 6 and the centralizer 7 are sleeved on the outer wall of the tubing 4 in sequence from top to bottom.
[0015] The power part 8 is a telescopic assembly that can drive the cutter and the ball seat nozzle 11 to move up and down in the vertical direction, and its telescopic distance is 20cm. The cutter and the ball seat nozzle can be driven downward by 20cm from the reset position through the telescopic assembly.
[0016] Wherein, the telescopic assembly can adopt a hydraulic teles...
