Abstract
The utility model discloses a monitoring device for exploding a perforating hole, aiming at providing a monitoring device for exploding the perforating hole, which is safe in measurement and high in accuracy. By monitoring vibration wave which is transmitted along a pipe column and an earthquake wave signal which is transmitted along a stratum and by computing with ground software, the monitoring device can overcome the influence of the other vibration signals, can remove the influence of a plurality of underground tools such as a packer and the like, can exactly and automatically judge whether a perforating device is safely exploded, can explode a joint with time delay, and can judge the safe exploding condition of a long-well segment and a long-span perforating hole gun string; and the device can remove the potential safety hazard that a constructor touches an oil pipe of a well opening at the well opening to judge whether the perforating device is exploded, so that the happening of the safe accidents can be basically avoided. The device has the structure that an earthquake wave monitoring probe head and a vibration wave monitoring probe head are respectively connected with an acquiring faceplate, and the acquiring faceplate is connected with a computer by a universal serial bus (USB). The monitoring device is applicable to the field of oil well logging.
Description
Technical field
The utility model belongs to and relates to a kind of monitoring device that detonates, and particularly relates to a kind of detonate device of situation of perforator when monitoring the perforating oil gas well operation.
Background technology
In petroleum industry, the oil well perforation operation is that high lined-cavity charge, detonating fuse and pressure break gunpowder are installed in the perforating gun by some, treat behind the target zone of down-hole, to ignite under the perforating gun, high lined-cavity charge after the ignition forms the liquid metal jet of a high temperature, high pressure, after perforating gun penetrated, further penetrate sleeve pipe and the cement sheath of wearing the borehole wall and enter the stratum, the stratum is communicated with oil well, reach formation fluid and can successfully flow into purpose in the oil well.
Generally speaking, in the perforation completion operation, the detonate judgement of situation mainly relies on the constructor to feel the vibrations of oil pipe to perforator, this method exists many safety latent, especially when adopting pressure to detonate, there is potential safety hazard in the constructor at high-pressure well mouth, secondly the vibration influence constructor's of external interference generation judgement.
Though replacing personnel's sensation, the monitoring of conventional TCP monitoring recognition system by instrument judge the main monitoring oil pipe shock wave that relies on.But it is relatively poor for the special well monitoring effect, vibration signal that can not instrument start-up produced with going into the well is distinguished with the perforator time break, packers etc. are gone into the well the vibration signal passage are cut off, and the perforation signal can not reach ground along oil pipe, and measurement accuracy is relatively poor.
The utility model content
The utility model is at the problems referred to above, and a kind of security measurement, perforation that accuracy the is high monitoring device that detonates is provided.
For achieving the above object, the utility model perforation detonates, and monitoring device comprises shock wave monitoring probe 1, gathers panel 3, computer 4, seismic wave monitoring probe 2 is connected with collection panel 3 respectively with shock wave monitoring probe 1, gathers panel 3 and is connected with computer 4 by USB.
Shock wave monitoring probe 1 is installed in well head and can monitors along the position of the shock wave of tubing string transmission.Ground can monitor along the position of the seismic wave of stratum transmission near seismic wave monitoring probe 2 was installed in well head.About more than 20 meters of seismic wave monitoring probe 2 chosen distance well heads.
The beneficial effects of the utility model are, the perforation monitoring device that detonates involves the seismic signal that transmits along the stratum by monitoring along the vibrations of tubing string transmission, calculate through software on ground, can overcome the puzzlement of other vibration signal, the influence that downhole tools such as elimination packer bring, accurately automatically judge whether safe initiation of perforator, and be used in combination the time-delay priming adapter, can judge the safe initiation situation of long well section, large span perforating gun string; This device has been eliminated the constructor and has been judged the potential safety hazard whether perforator detonates at well head touch well head oil pipe, has fundamentally avoided the generation of security incident; Increase the seismic wave monitoring, solved the difficult problem that special gun perforation process such as perforating test connection work can't accurately be monitored the perforator safe initiation.
Description of drawings
Fig. 1 is the utility model perforation monitoring device structural representation that detonates;
Fig. 2 is the utility model perforation monitoring device signal flow graph that detonates.
The specific embodiment
As shown in Figure 1, 2, the utility model perforation detonates, and monitoring device comprises shock wave monitoring probe 1, gathers panel 3, computer 4, seismic wave monitoring probe 2 is connected with collection panel 3 respectively with shock wave monitoring probe 1, gathers panel 3 and is connected with computer 4 by USB.
Before perforator is ignited in caber or pressurization, shock wave monitoring probe 1 is installed in the well head correct position, as under the well head gate or tubing head position.About more than 20 meters of seismic wave monitoring probe 2 chosen distance well heads, ground are hard, soil solid place insertion is underground, and no pedestrian walks about near the control probe.Notify the related personnel to carry out caber or pressurization, ignite perforator, the signal of seismic wave monitoring probe 2 and shock wave monitoring probe 1 sends computer 4 to after gathering panel 3 noise processed, A/D conversion, computer 4 writes down the signal that receives accordingly, shows, stores; Simultaneously can Real Time Observation on display screen to the time domain waveform and the frequency-domain waveform of signal; Behind the signal data record, analyze identification by comprehensive two waveforms, can judge the situation of detonating of perforation accurately:, accurately judge the ignition of identification perforator, detonator detonates, Tapper perforate, barred body percussion primer, the sharp self-destruction of multistage rod etc. by the shock wave that monitoring is transmitted along tubing string; By the seismic wave that monitoring is transmitted along the stratum, accurately judge the perforator ignition, and the demonstration on the effect stratum of monitoring compound technique of perforating.
The perforation monitoring device that detonates involves the seismic signal that transmits along the stratum by monitoring along the vibration of tubing string transmission, calculate through software on ground, accurately automatically judge whether safe initiation of perforator, and be used in combination the time-delay priming adapter, can judge the safe initiation situation of long well section, large span perforating gun string.This system has eliminated the constructor and has judged the potential safety hazard whether perforator detonates at well head touch well head oil pipe, has fundamentally avoided the generation of security incident; Increase the seismic wave monitoring, solved the difficult problem that special gun perforation process such as perforating test connection work can't accurately be monitored the perforator safe initiation.
