Abstract
The present invention relates to one technological system for completing negative pressure perforation of oil well, formation test and jet flow pump liquid drainage in once operation. The technological system includes perforator, formation testing unit, jet pump, sand supporting leather cap, positioning short joint, negative pressure jet pump, test pressure gage, testing unit, pressure transmitting joint, damper, igniting head, perforating gun, oil pipe, etc. connected successively. The said triple operation can speed construction, reduce secondary formation pollution and raise the quality of the acquired formation data.
Description
Technical field
The present invention relates to the underbalance perforating of Pressure Curve in Oil Testing Well and a kind of process system of a formation testing and a construction operation of jet pump discharge opeing.
Background technology
In the past, Pressure Curve in Oil Testing Well mainly adopted the formation testing method that TCP (perforation) DST (formation testing) two does.Its major defect is to be subjected to oil pipe (or drilling rod) content constraints, can't finish its discharge opeing work fully in nonflowing well, usually causes the unclear situation of fluidity and production capacity, has influenced the formation testing progress.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, is one and a kind of beam hole, test, discharge opeing are provided, and effective perforation and formation testing and jet pump three are made the fluid-discharge technology system.
Can take following technical scheme to realize purpose.
Perforation and formation testing and jet pump three are made the fluid-discharge technology system, comprise perforation, formation testing device, it is characterized in that: also have jet pump, holder rubber bowl, connect and compose by oil pipe.
The relative prior art of present technique has following advantage and effect
But the negative pressure jet pump can connect into the supporting use of disposable tubing string with TCP+DST technology under the prerequisite that does not influence perforation and formation testing, fully finish its discharge opeing work, thereby has improved the effect of formation evaluation; TCP+DST+JET three combination operation process systems have accelerated formation testing speed greatly, have improved operating efficiency, have avoided the secondary pollution on stratum simultaneously, and it is applicable to all kinds of oil gas water wells of well depth≤4500m hole deviation≤72 °, discharge capacity≤600m
3/ d; But the negative pressure jet pump has positive and negative row's function, its volume is little, discharge capacity big, reliable operation, and external sliding sleeve in the negative pressure that having to pressurize opens, thereby guaranteed the negative pressure performance of tubing string, designed the husky leather cup of dustproof bypass type holder simultaneously, mainly prevented factor because of formation sand production, sand card tubing string, guaranteed finishing of sleeve pipe pressurization igniting perforation, when playing lower tubular column, link up up and down, reduce resistance, effective.
Description of drawings
Accompanying drawing is that perforation and formation testing and jet pump three are made the fluid-discharge technology system schematic.
The specific embodiment
In conjunction with embodiment technical scheme is described in detail.
Embodiment 1, perforation and formation testing and jet pump three are made the fluid-discharge technology system, comprise perforation, formation testing device, also have jet pump 2, holder rubber bowl 3, connect and compose by oil pipe 1.
Embodiment 3, perforation and formation testing and jet pump three are made the fluid-discharge technology system, and on embodiment 1 or 2 bases, rubber tray 3 is dustproof bypass type.
Its operating principle, behind the following complete body tubing string, finish perforation and formation testing work earlier, when formation fluid is not enough to when up-flow goes out well head, the negative pressure sliding sleeve that is just pressurizeing and opening jet pump, in oil pipe (or drilling rod), drop into jet pump working barrel core (pump core portability pressure gauge and sampler as requested) then, after the pump core puts in place, well depth and production capacity situation according to well are adjusted ground high voltage power pump to the required operating pressure of jet pump, can finish the discharge opeing work on stratum smoothly by fixed tubular column, after the end, the well-flushing that recoils can be gone out the working barrel core of jet pump.
Claims (3)
1, a kind of perforation and formation testing and jet pump three are made the fluid-discharge technology system, comprise perforation, formation testing device, it is characterized in that: also have jet pump, holder rubber bowl, connect and compose by oil pipe.
