Embodiment
Fully digesting on the basis of understanding the each mainstream data file layout of industry of logging well both at home and abroad, the present invention first starts with from logical organization, and in conjunction with logging well, demand for services has been carried out Logic Structure Design to log data file.
Fig. 1 shows GDS(GeoScope Data System of the present invention) Real-time Logging data file general structure.Each GDS Real-time Logging data file comprises a file header and multiple logical file as can be seen from Figure 1, and each logical file comprises again multiple data objects, and each data object comprises data object head and data object content.
Logical file is mainly used to data object to carry out Classification Management, and Fig. 2 reflects the logical organization of the logical file of GDS Real-time Logging data file.
As can be seen from Figure 2, each logical file is made up of logical file object head and multiple data object start position information.No matter be logical file or data object, physically all adopt data capsule object (DataContainer) to realize, therefore logical file object head has specifically comprised the full content of a data container object head (DataContainerHeader).
GDS data file can comprise the concrete data object of number of different types, as supplemental characteristic object, list data object, frame data object etc.As service needed user also can expand more data object, for example, text data object or flow data object etc.
Frame data use maximum a kind of data objects to liking in the various data objects of GDS Real-time Logging data, and all borehole log datas are all stored with frame data object.Fig. 3 has reflected the logical organization of GDS frame data objects.
Frame data object is made up of frame data object head, passage description block and three parts of frame data.Frame data object physically adopts data capsule object to realize, and therefore frame data object head has specifically comprised the full content of a data container object head, and expands for frame data object.
Each frame data object has comprised multiple passage objects, a corresponding logging trace of passage.The passage description block of frame data object has provided the descriptor of each passage object in this frame object.
The data of multiple passage objects are arranged in order, have formed a Frame.Multiple Frames have formed the total data of frame data objects.Fig. 4 shows the frame data structure of GDS Real-time Logging data file.As can be seen from Figure 4, each data frame packet has contained a frame index data and multiple channel data piece.Multiple data samples that each channel data piece has comprised respective channel, each sampling point data can be multidigit dimensions, give the example of two-dimensional channel sampling point data in Fig. 4.
The list data object of GDS Real-time Logging data file is used for the data of storage list case form, and Fig. 5 has reflected the structure of GDS list data object.
List data object physically adopts data capsule object to realize, and therefore list data object head has specifically comprised the full content of a data container object head, and expands for list data object.
The supplemental characteristic object of GDS Real-time Logging data file is used for storage of hierarchically supplemental characteristic, and Fig. 6 shows the structure of ginseng data object.
As can be seen from Figure 6, each supplemental characteristic object comprises parameter hierarchical information district (Zone) sequence and multiple parameter.Each district (Zone) has in fact defined a start-stop degree of depth pair, and parameter object provides the parameter value of Liao Ge district (Zone).
On GDS Real-time Logging data file Logic Structure Design basis, can need designing user access interface standard BasicIOSpec software package according to practical application, developer uses this standard can access GDS data file and various data object thereof.Fig. 7 shows the class framework according to BasicIOSpec software package of the present invention.
In Fig. 7, GDS data are mainly by IDataFile, ILogicalFile, and the object of tri-logical levels of IDataObject forms.IDataFile is corresponding to a concrete GDS data file, and each IDataFile can comprise multiple ILogicalFile logical files, and each logical file can comprise again multiple IDataObject data objects.
IDataObject is the base class of GDS data object, GDS data object can have multiple concrete form, for example: frame data object IFrameDataObject, list data object ITableDataObject, supplemental characteristic object IParameterDataObject, flow data object IStreamDataObject and text data object ITextDataObject.
On the basis of access interface standard BasicIOSpec, can realize this access interface with C#, and GDS data file access class libraries BasicIO.dll corresponding to compiling generation, this class libraries can supply concrete application call.In order to guarantee the performance requirement of Real-time Collection, in the specific implementation of BasicIO, can carry out performance optimization to the many places details of data access.
The present invention adopts Stratified Strategy in GDS data file Logic Structure Design, be divided into generally three levels of file → logical file → data object, be the balance of completeness and terseness, can guarantee to meet the actual needs of complicated production service, guaranteed again the terseness of logical organization.
Data object can be embodied as the several data object types such as text, binary stream, XML, form, parameter, frame, and frame data object has again the sampling feature that time, the degree of depth etc. are different.So just can guarantee the support of the various data recording of the various well logging services to wireline logging, well logging while drilling, production logging etc.
In physics realization, the present invention introduces the concept of blocks of data object, and all data objects all derive from blocks of data object.The data block record that each blocks of data object is linked by multiple front and back forms.Adopt after blocks of files mechanism, growth data object or deletion available data object generally do not need file to carry out large reformation, therefore from mechanism, overall performance are optimized, and are applicable to doing the various logging operation tasks such as Real-time Collection and aftertreatment.
In the time that concrete data access is realized, can take a series of data retrieval, buffer technology, further promote the performance of data access.
Aspect user's access interface, can set up the access interface object corresponding with logical organization, easy to understand memory, uses also more convenient.
