Abstract
The utility model discloses an oil and gas well perforating ground monitoring device which comprises a notebook computer, a vibrating sensor and an analog-digital conversion module. The analog-digital conversion module is connected with the notebook computer through a universal serial bus (USB) interface. The notebook computer is connected with the vibrating sensor through the analog-digital conversion module. A battery of the notebook computer is used for supplying electricity to the analog-digital conversion module. The monitoring device monitors vibration wave signals transferred along a pipe column and earthquake wave signals transferred along the stratum, processes the signals through ground software, and accurately judges whether a perforating device is safely detonated via through monitoring. Therefore, the potential safety hazard that constructors touch a well mouth oil pipe at a well mouth to judge whether the perforating device is detonated is eliminated, increases earthquake wave monitoring and pressure auxiliary judging criterions, and enhances accuracy of the judgment. When the monitoring device works, all components are powered through the battery of the notebook computer, consequently, the monitoring device is simple in structure, light in weight, capable of being transferred rapidly through deploy, and convenient to carry.
Description
Technical field
The utility model relates to the monitoring device that detonates, concrete a kind of perforating oil gas well ground monitoring device.
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 vibration 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 there was report to be presented in the instrument that ground monitoring downhole perforation rifle detonates in early days, the variation of ground pressure judged in the synchronization sudden change whether perforating gun detonates according to vibration wave and pressure when its principle involved pressurization along the vibration of tubing wall transmission when perforating gun detonates under the received well on the ground.But being site operation personnel's authority experience and this, such judgement do not have to make under the situation of other noise signal in the well site constantly, rather than the judgement made automatically of instrument.The tracer signal that belongs to passive type.
And device structure complexity in the past, equipment is heavy, is not easy to carry and disposes fast, shifts.
Summary of the invention
At above-mentioned technical problem, the utility model provides a kind of portable type ground monitoring device that can judge automatically that perforation detonates.
The technical solution of the utility model is: a kind of perforating oil gas well ground monitoring device, comprise notebook computer and vibrating sensor, also comprise an analog-to-digital conversion module, described analog-to-digital conversion module is connected with described notebook computer by USB interface, described notebook computer is connected with vibrating sensor by described analog-to-digital conversion module, and described analog-to-digital conversion module is powered by cells in notebook computer.
