Description
Technical field
The present invention relates to a kind of forward probe with sensor string and veer away device and fixing means in directional drilling, be applicable in the elastic wave forward probe.
Technical background
The linear array string can receive the various direct waves that come from the source, also receives the various elastic waves that reflect from string the place ahead simultaneously.In the seismic prospecting theory; Two type of elastomeric wavelength-divisions do not belong to descending ripple and upward traveling wave; Because therefore their difference on apparent velocity can be extracted the reflection wave from string the place ahead through the row wavelength-division from algorithm preferably, and suppress various direct waves; Through further processing and migration imaging, can form respond well, widely used geology advanced prediction method of exploration and equipment to reflection wave.Like the TSP system that Switzerland An Boge company produces, TGP forward probe system that Beijing water power physical prospecting research institute produces or the like.
The technical now various advanced prediction system that is in industry-leading adopts the work pattern of many big guns focus and 1～2 receiving sensor, need form big gun hole, 24 left and right sides with explosive as focus.The expansion in big gun hole need can only be surveyed the geologic hidden peril of front of tunnel heading towards face usually than large space, and is then powerless for the detection of side, end face and bottom surface; Sensor is laid needs special coupling steel pipe, is used as consumptive material and uses, and causes a large amount of wastes, and technology is comparatively complicated in the forward probe construction, and holding time is also longer; In addition, in underground engineering constructions such as colliery, wait operating type to be limited basically owing to blow out, the serial advanced prediction system of therefore similar TSP is difficult in the roadway of colliery, put to good use; Several kinds of existing exploration operation instrument and equipment cost an arm and a leg, and are difficult to accept extensively for engineering circle.Therefore press for a kind of simple and easy to do detection operating type in Tunnel Engineering circle, can realize the elastic wave advance geologic prediction quickly and easily, especially in the limited underground space, carry out the forward probe of all directions; And this breakthrough needs the sensor reception seismic event of arranged in arrays.
In addition, owing to explosive source in rock mass, the consistance of focus is difficult to solve, and the shot firing operation mode can not repeatedly excite in same point, can not form the stack of elastic wave signal; The fixed coupling of sensor is difficult in the rock mass, needs complicated technology to guarantee the adherent coupling of three-component sensor like the TSP system; The installation coupled problem that solves focus problem and sensor is the successful key of elastic wave advanced prediction
.
Summary of the invention
