Description
Technical field
The utility model relates to oil and geological exploration techniques field, specifically is a kind of sensor string equipment that is used for the shallow-layer geologic examination.
Background technology
Along with the resolution of geologic prospecting and petroleum prospecting improves constantly, the correction of interfere with layer is also required thereupon higher, it is that the workload of shallow-layer investigation also strengthens thereupon that a job is arranged in two dimension, 3-d seismic exploration in recent years.The every KM2 that requires that has has a micro logging calibration point, and a 3-D seismics section has 500～600 micro logging workloads.So the work efficiency of micro logging, operating accuracy and cost can directly have influence on the precision and the cost of 3-D seismics or other seismic work.Present situation is whenever to do a micro logging, just beat the dark well of 35～50M flatly, then with under the multitap cable in well, per 1～2M ties up several detonators or a detonator adds tens gram explosives, put the shake wave detector of enclosing the land on ground, roll-along shooting from deep to shallow, ground receives, just can obtain direct wave speed and the decay of each point to ground, do like this and just can ask speed and the decay of each point to ground, the former is more accurate, and attenuation coefficient then can be subjected to differing in size of each point dose and try to achieve inaccurate, even the point that has do not explode or blown up and can not get data, influences the micro logging quality.But prior art exists the explosive source consistance poor, produces the quick-fried or broken string of mistake and causes certain degree of depth to excite to have no resolution, and can not reuse with dangerous, dangerous, destroys shortcomings such as environment.
The utility model content
In order to address the above problem, the utility model provides a kind of sensor string equipment that is used for the shallow-layer geologic examination.
The technical solution of the utility model is: a kind of sensor string equipment that is used for the shallow-layer geologic examination, it comprises telescoping ram string, sensor string and ground power unit.

Described ground power unit is the combination of a minitype gasoline power generator and scalable air pump, and its effect is to arrive certain pressure or venting by pipe to airbag aeration, and it is supporting to belong to outsourcing, does not just describe in detail here.
Shock wave sensor in the sensor shell can be the single-sensor that has only vertical component, also can be three sensors of two orthogonal components of tyre level.
The quantity of described telescoping ram unit is between 5 to 100, and the quantity of described sensor unit is between 5 to 100, and the data of Cai Jiing are more accurate like this.
This equipment telescoping ram is at test site attaching bunchiness, and sensor string is middle at the scene with the corresponding load with telescoping ram of nylon cable tie, and with return spring sensor and air bag is forced together.The surface seismic instrument is connected with sensor string with cable, so that the signal that collection and processes sensor receive.
This equipment is the important component part of the equipment of shallow-layer geologic examination, be used for shallow-layer VSP investigation, key link is to have adopted by ground control air bag telescoping ram, guarantees the coupling of the sensor and the borehole wall (being the stratum), is convenient to receive better the seismic event that focus sends.
Present domestic this kind form sensor string equipment that still do not have has following advantage compared with prior art:
1. sensor high conformity, observation station is apart from accurately;
2. the epicenter excitation consistance guarantees (impulsing with the hammering method on ground) easily;
3. without explosives and detonators, safety, reliable is protected environment;
4. equipment can conveniently change the observation station distance, and reusable;
5. equipment is light, and construction cost is low.
