Abstract
The invention discloses a kind of mass data downhole stored method for wireline logging, suitable for the big downhole logging instruments of gathered data amount.This method is in well logging, and the log data of measuring probe collection after preliminary treatment early stage, under the SECO of logging system, is cached in buffer, in order to which the further data pick-up of data uploads and stores.Then data again under control, be stored in storage physical medium in.Meanwhile the data in buffer are stored in, ground system is uploaded to according to extraction partial data is actually needed, so that operating personnel carry out logging data quality control and man-machine interactive operation.Can thus realize that underground gathered data downhole instrument all stores, partial data is uploaded, and raising is tested the speed, and reduces cost, with meet to log well now market the needs of.
Description
Technical field
The present invention is a kind of date storage method, especially a kind of mass data downhole stored side for wireline logging
Method, factor data amount is big suitable for all wireline loggings, influences the logger of logging speed.
Background technology
In wireline logging, some logging methods such as nuclear magnetic resonance log, electric imaging logging, orientation far detect acoustic imaging well logging
Because log data amount is big, logging speed is had a strong impact on, causes well logging timeliness low, cost height, exploration cycle, length, did not utilized well logging side
The lasting wide popularization and application of method.
The content of the invention
The present invention relates to a kind of mass data downhole stored method for wireline logging, and number is gathered suitable for any one
According to big wireline logging is measured, well logging speed per hour can be effectively improved using this method, improves exploration cycle, reduces application cost.
To reach above-mentioned purpose, the invention provides a kind of mass data downhole stored method for wireline logging, bag
Include following steps：
Step 1, by the magnanimity log data of each depth point after preliminary treatment early stage, under SECO in real time
Storage, while according to demand, selection uploads partial data and is used to gather data quality detection and man-machine interaction demand；
Step 2, terminate in well logging, after proposing well head on instrument, with data wire is read, by the whole of downhole instrument storage
Well-log information takes out, and is pre-processed, played back, handling explanation.
The step 1：In well logging, the log data of measuring probe collection after preliminary treatment early stage, is being surveyed
Under the SECO of well system, it is cached in buffer, in order to which the further data pick-up of data uploads and stores；Data exist
Under control, it is stored in the expansible FLASH storage physical mediums of multi-disc, during storage, using customized address bus and logical
News mode, under certain programme-control, realize the fast and reliable storage of gathered data；Meanwhile the data in buffer are stored in,
According to be actually needed extract partial data upload to ground system, so as to operating personnel carry out logging data quality control and it is man-machine
Interactive operation.It can thus realize that underground gathered data downhole instrument all stores, partial data is uploaded, and raising is tested the speed, and is dropped
Low cost, with meet to log well now market the needs of.
The beneficial effects of the invention are as follows：Certain huge logging technique of each depth point gathered data amount can be made, even
In continuous well logging, the log data amount uploaded in real time is reduced, improves logging speed, reduces logging cost.It can make to have existing
The logging method of defect, after using this method, well logging timeliness is improved, there is well logging advantage, be easy to promote, be widely used
Prospect.
Embodiment
The present invention is described in further detail with reference to embodiment：
The mass data downhole stored method for wireline logging of the present invention, comprises the following steps：
Step 1, by the magnanimity log data of each depth point after preliminary treatment early stage, under SECO in real time
Storage, while according to demand, selection uploads partial data and is used to gather data quality detection and man-machine interaction demand；
Step 2, terminate in well logging, after proposing well head on instrument, with data wire is read, by the whole of downhole instrument storage
Well-log information takes out, and is pre-processed, played back, handling explanation.
The step 1：In well logging, the log data of measuring probe collection after preliminary treatment early stage, is being surveyed
Under the SECO of well system, it is cached in buffer, in order to which the further data pick-up of data uploads and stores；Data exist
Under control, it is stored in the expansible FLASH storage physical mediums of multi-disc, during storage, using customized address bus and logical
News mode, under certain programme-control, realize the fast and reliable storage of gathered data；Meanwhile the data in buffer are stored in,
According to be actually needed extract partial data upload to ground system, so as to operating personnel carry out logging data quality control and it is man-machine
Interactive operation.It can thus realize that underground gathered data downhole instrument all stores, partial data is uploaded, and raising is tested the speed, and is dropped
Low cost, with meet to log well now market the needs of.
Embodiment
Certain acoustic logging instrument needs to gather 120 all-wave column datas in each depth point, and the per pass wave train gathers 2048
Point, sampling resolution 16, then the data volume of a depth point is about 5Mb.And the transmission speed of remote measurement used is 1Mb/S, institute
To need the time of 5 seconds could be by all gathered data end of transmissions, logging speed now be 2m/min.Receiving transducer will
The acoustic signals received its be changed into voltage signal after, it is medium by amplifying, filter, sram chip being cached in after analog-to-digital conversion
Treat ensuing data storage and extract to upload.Under the control of control panel, the total data collected is fast from sram chip
Speed store exactly in high-capacity FLASH storage chip, and from data every 4 data pick-ups, 1 data simultaneously, controlling
The lower extraction partial data of system uploads to ground system and monitored in real time.If the data of selecting extraction 1/3rd, in theory
Logging speed can improve three times, and logging speed now is 6m/min.After the completion of instrument logging tasks, instrument is mentioned ground
Behind face, ground notebook computer, data reading circuit plate, downhole instrument are connected.Notebook computer sends related read and instructed,
The total data that downhole instrument stores is read in the notebook computer of ground.FLASH number is carried out after digital independent
According to erasing and null clear operation, FLASH is reduced into state to be deposited, system playbacks before being logged well in order to next time.
In summary, present disclosure is not limited in the above embodiments, and the knowledgeable people in same area can
Can propose other embodiments easily within the technological guidance's thought of the present invention, but this embodiment is included in this hair
Within the scope of bright.
