สตริง Micro Logging Downstone

Technical background: At present, are using micro logging technology is adopted in well inspired, ground geophones way, basically have two kinds of methods. One kind is point-by-point set point stimulate, namely: The successive will each point of dynamite sent to reserve depth, complete set lodging a cannon inspired, ground geophone successive receiving records each point of seismic signal. Another kind of business is the first after setting, namely: First will stimulate each point of dynamite sent one downhole predetermined position and fixed, in all stimulate point Settings are complete, then each inspired, ground geophone again by collecting and recording the point of seismic wave signal stimulate. The existing technology's weakness is:

The actual explosion stimulate point and construction design depth can't accurate anastomosis, because each point of downhole stimulate, frequency, effective potter levy effect also is different, so the seismic data consistency unreliability, point-by-point set point stimulate methods caused easily across step, make behind sidewall of setting cannot undertake, first after setting stimulate approach, by dozens of connections, the Numbers of the connecting caused easily mistake, and would lead to stimulate errors, lines are disabled, short circuit or leakage. In addition, the existing methods applied in a time-consuming, and the intensity of labor is very large.

In order to overcome the existing seismic signal acquisition technology (namely point-by-point set point shooting technique, first after setting a shooting technique) insufficiency, nanchong hawks technology Co., Ltd. has been developed with advanced in underground seismic signal detectors receiving string.

Working principle: According to the construction design requirements will geophone according to certain spacing string up in transmission cables, formed in underground seismic signal detectors receiving string. When construction, will geophone string into well, detectors in heavy hammer of string gravity arrived at the scheduled depth after start-up geophone push by device to make the geophone string clingy in shaftlining and then challenging seismic signal source, acquisition, signal acquisition is completed, release pushed by device, will drop to a new string geophone depth again acquisition signal.
Product advantage: One-time get different seismic signal horizon, high efficiency, simple operation, stable performance, waterproof insulation, saves time and effort.

Areas of application:
Used in seismic signal acquisition fields, such as oil seismic exploration, geological prospecting, geological mining city construction planning engineering exploration, hydraulic engineering geological prospecting etc.
