Description
Technical field
The utility model belongs to geology clothing arts, is specifically related to a kind of geology outcrop gamma instrument.
Background technology
The radioactivity of rock is caused by U, Th, K system radioactive isotope contained in rock, these elements all release gamma-rays in nature decay process, and the gamma-ray quantity of different element releasing and energy are all had any different, determine content and the kind of radioelement in rock, can be used for finding radioactive occurrence and Study of Strata character.The radioactivity of sedimentogeneous rock is lower than magmatite and metamorphosed rock, and in sedimentogeneous rock, natural gamma radioactivity increases with the increase of shale index.This principle has been widely used in the gamma logging technology of oil field, because different lithology stratum has different natural radioactivity intensity, utilizes the gamma ray intensity in gamma detector detecting shaft sub-surface, can distinguish stratum and determine stratum element.Wherein natural gamma ray log technology mainly measures gamma intensity, its measurement mechanism is made up of subsurface equipment and surface instrumentation, gamma ray in stratum arrives detector by mud, detector converts electric pulse to the gamma ray received, and carry out amplification formation electric signal, arrive surface instrumentation by cable again, be transformed into electric pulse number/(intensity) per minute and carry out record, obtain the natural gamma intensity of rock stratum.
Field Geology Investigations is the important means that geologist obtains the firsthand data and data, is also the basis of geological work, and along with the progress of geological sciences technology and going deep into of Exploration, the precision of Field Geology Investigations has much room for improvement.The principle that the utility model provides a kind of Portable field to appear gamma instrument, foundation down-hole gamma logging, measures the intensity of the natural gamma rays of outcrop rock, for field work provides reliable data source.Outcrop gamma instrument is widely applicable, can be used for the exploration in coal exploration and relevant uranium ore, potassium ore deposit, can identify rock type, shale index and analyze rock formation environment etc. according to gamma intensity.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of geology outcrop gamma instrument, and this tool body part is gamma sensor, photomultiplier, computing chip, display screen, feedback module, battery.This utility model is simple to operate, gamma instrument is aimed at rock outcrop in the wild, can measure the intensity of the natural gamma rays of this rock, obtains relevant geological information intuitively.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of geology outcrop gamma instrument, its structure comprises gamma sensor, photomultiplier, computing chip, display screen, feedback module, battery, it is characterized in that: described gamma sensor can accept gamma ray, be connected with photomultiplier, described photomultiplier is connected with computing chip, described photomultiplier is connected by feedback module with computing chip, described feedback module is by feedback circuit correction calculation result, described display screen is for showing the output data of computing chip, described battery is used for gamma sensor, photomultiplier, computing chip, display screen, feedback module is powered.
Design concept of the present utility model:
Geology outcrop gamma instrument is familiar with rock stratum by the intensity of the natural gamma rays of measurement rock stratum, and it is the intensity measuring the gamma ray radiating out in the radioelement nuclear decay process of existence naturally in rock stratum.Gamma ray in stratum enters in gamma sensor and matter interaction, produce electronic secondary by three kinds of effects, electronic secondary makes scintillator in sensor excite, and produces fluorescent photon during de excitation, by photon collection on the photocathode of photomultiplier, produce photoelectron.Photoelectron quantity in photomultiplier increases several order of magnitude, and the electron stream of formation produces electronic pulse signal in plate-load.Electronic pulse signal chip process as calculated, record, obtain gamma value and show on a display screen.
The beneficial effects of the utility model:
Can be found out by above-mentioned principle design, a kind of geology outcrop gamma instrument volume that the utility model provides is little, lightweight, easy to carry in geological work in the wild; Simple to operate, feasibility good, accurately can measure the intensity of the natural gamma rays of outcrop rock, obtains relevant geological information intuitively.
