Description of drawings
Fig. 1 illustrates the structural drawing according to the down-hole well logging apparatus of the utility model;
Fig. 2 illustrates the structural drawing according to the ground well logging apparatus of the utility model.
Embodiment
Hereinafter, identical Reference numeral refers to components identical.
The well logging apparatus of the utility model mainly comprises data sensor part, data acquisition process part, data storage part; Wherein, Data sensor partly induces the various physical parameters in the stratum, and data sensor partly is connected to the data acquisition process part, thus; The various physical parameters that the data acquisition process part is sensed the data sensor part are carried out acquisition process; The data acquisition process part further is connected to the data storage part, and therefore, the various data of institute's acquisition process will be stored in the data storage part.The data storage part can be taken out from well logging apparatus separately, for example adopts computer that the data of being stored in the data storage area are carried out analysis interpretation subsequently.
The well logging apparatus of the utility model both can be used for the downhole data collection, and can be described as " down-hole well logging apparatus " this moment, and it is dark also to can be used for the ground meter, can be described as this moment " ground well logging apparatus ".
Carrying out downhole data when gathering, at first adopt drilling tool in the rock stratum, to get out a boring, thereby the down-hole well logging apparatus can be placed on to be fixed in the basket on the drilling tool and move flexibly up and down with drilling tool.
Fig. 1 illustrates the structural drawing according to the down-hole well logging apparatus of the utility model.
As shown in Figure 1, down-hole well logging apparatus 100 comprises data sensor part 101, data acquisition process part 102, data storage part 103.Data sensor part 101 is made up of one or more sensors.Data acquisition process part 102 can be made up of the c8051f020 single-chip microcomputer, and data storage part 103 can be data memory module, and the output of data serial ports directly is stored in the SD card, and traffic rate can be provided with according to configuration file in the SD card voluntarily.
Preferably, data acquisition process part 102 is connected with a clock generating device 104, this each set time of clock generating device (for example, each frame) flag data, thus can be according to unified time data being made up when data analysis is subsequently explained.More preferably, this clock generating device adopts clock chip ds12c887.
Said sensor comprises one or more in the sensors such as natural gamma sensor, artificial gamma sensor, resistivity sensor, inclination sensor, azimuth sensor, sonic sensor.
Hereinafter will introduce the natural gamma sensor.The natural gamma sensor is responsible for measuring the natural radioactivity intensity of rock in the stratum.In coal logging, utilize natural gamma ray log, mainly solve the division of rock stratum and the contrast on stratum.The natural gamma sensor can sense the gamma ray from the radioelement in the boring rock stratum.
At occurring in nature, sedimentogeneous rock all has radioactivity in various degree, and the content of the radioelement in the sedimentogeneous rock is relevant with rock composition and mode of deposition, and the natural radiation intensity of sedimentogeneous rock can be divided into strong, inferior strong, medium, weak, inferior weak five types.Radioelement in the rock stratum is launched three kinds of rays in the transformation process, wherein gamma ray penetration power chamber is easy to survey and is applied in the well logging.
In the process of gamma ray through the scintillation crystal of gamma sensor, crystal sends faint light.
Preferably; Can also make gamma sensor be connected with a photomultiplier; Comprise the NaI crystal in the photomultiplier, the data of gamma sensor institute sensing can be passed through the photomultiplier amplification, thereby make data acquisition process part 102 more easily carry out acquisition process to corresponding data.
Then introduce artificial gamma sensor again.Artificial gamma sensor adopts the porosity log method, and its principle is according to the density size of being surveyed object the effect that gamma ray generation Compton effect forms to be surveyed.
Different rocks has different density, utilizes different density to divide different rock stratum.When adopting artificial gamma to carry out density logging, can adopt isotope Cs137, it can emit the gamma ray of 0.66MeV energy in decay process.This gamma ray with the matter interaction process in energy decay takes place and disappear.The Compton effect that in the energy attenuation process, takes place is proportional with the density of being surveyed object.
Preferably, the data acquisition process part can be connected to power supply via mercury cut-off.For example, data acquisition process part 102 shown in Figure 1 is connected to power supply 106 via mercury cut-off 105.Thereby the entire circuit that the mercury cut-off that when rig is mentioned drilling tool, is in plumbness just can the conducting well logging apparatus begins to get into countdown work.Data acquisition process part 102 just began image data when countdown finished, and and then with data storage in data storage part 103.After the well logging process is accomplished, can set level well logging apparatus, thereby make mercury cut-off be in horizontality, thereby make the well logging apparatus outage and quit work.In the case, just can take out the data content that is stored in the data storage part 103 and carry out analysis interpretation.
Preceding text are mentioned, and well logging apparatus of the present invention except the well logging apparatus of down-hole, also can comprise the ground well logging apparatus.
Fig. 2 illustrates the structural drawing according to the ground well logging apparatus 200 of the utility model.Ground well logging apparatus 200 comprises data sensor part 201, data acquisition process part 202, data storage part 203.
The ground well logging apparatus mainly is used for measuring the degree of depth of drilling well.As shown in Figure 2, data sensor part 201 can be regarded as the dark device of pulley meter herein.Drive drilling tool up and down during operation at the elevator of rig, wire rope drives the dark device of meter and rotates.Count and have photoelectric encoder 201a in the dark device, be used for converting amount of spin into depth data.Photoelectric encoder 201a is along with the rotation output respective depth data of pulley, and this voltage is gathered by data acquisition process part 202 again.Preferably, data acquisition process part 202 also is connected with clock generating device 204.Under the effect of clock generating device 204, every group of voltage can be in the laggard line data storage of mark time, thus with respective data storage in data storage part 203.
The well logging apparatus that the utility model adopted does not use winch, generator and special-purpose vehicle, has simplified the total system structure, and multiple functional, but the setting independent assortment of sensor.This well logging apparatus integral device is light and volume is little, can use flexibly.Especially, do not use cable communication according to the well logging apparatus of the utility model, thereby make the small and exquisite and low-power consumption of single unit system.Simultaneously, the radioactive source airtight performance is good, reduces operating personnel's raying amount.Underground well logging apparatus is owing to be fixed in the drilling tool deeply boring, also can not be trapped in undergroundly, reduced environmental pollution effectively.
Those skilled in the art will also be appreciated that the protection domain of the utility model is not limited in the foregoing description, and all equivalents to the utility model all drop in the scope of the utility model.
