Description
Technical Field
The utility model relates to an oil well logging field, concretely relates to a line device is walked in power supply for wireless transmission device pulse generator.
Background
The existing cable-free logging system adopts a drill pipe conveying pump-out storage type and consists of a drilling tool protective sleeve positioned outside, a releaser and an instrument positioned in the protective sleeve. The external drilling tool protective sleeve mainly comprises an upper suspension, a lower suspension and the like, and is mainly used for connecting the instrument with the drilling tool, suspending and fixing the instrument, so that the instrument is fixed in a drill rod and is kept still in the lowering process, and the instrument is prevented from being separated from the drill rod. The protective sleeve is internally hung with a mechanical releaser and an instrument string combination. The releaser has the function that when the instrument reaches the bottom of the well, the releaser can be suspended and separated from the drilling tool through the ground ball throwing, so that the purpose of releasing the instrument is achieved. The instrument is positioned in the protective sleeve, so that the instrument is not contacted with the stratum, and the instrument is protected.
However, there are the following problems:
firstly, in the instrument lowering process, if the shearing pin is sheared in advance due to some reason, the instrument is released in advance, the ground is still unknown, and the instrument is damaged due to the fact that the shearing pin is continuously lowered.
Secondly, after the shot is released, whether the shearing pin is sheared or not and whether the instrument is successfully pumped out of the drilling tool or not are judged only from the ground according to the change of mud pressure, and a positive conclusion cannot be obtained; for example, at the moment when the shear pin is sheared off, the pressure of the mud column rises sharply, a significant pressure change is supposed to be seen on the ground, but the pressure holding and shearing occur instantaneously for only a few milliseconds, and when the pressure value is acquired by software, dozens of times per second, a high-pressure peak is likely to be already ended in the acquired gap, and the acquired secondary peak may be submerged in the background noise. On the other hand, as the well depth increases, the pulse will decay with the well depth, and such a narrow pulse width may have already decayed during the upload, so there is not a great probability that the spike will be captured. And the contrast pressure exerted after the instrument is pumped out is also the pressure change before and after the water hole is opened is not obvious, and the pressure change is not obvious, so the instrument is often pumped out, but the pump pressure is continuously increased according to a non-pumping program until the pump pressure is highest, and the circulation is carried out for a certain period of time to ensure that the instrument is pumped out, so that the thrust exerted on the instrument is too large, and the instrument is often broken during actual operation.
Secondly, during the lowering process of the instrument or after the pumping-out of the instrument is finished, the instrument may not work normally due to vibration impact or other reasons, but ground personnel cannot judge whether the instrument is normal or not, and still perform logging operation normally, so that precious time is wasted.
