Problems solved by technology
[0003] The technical problem to be solved by the present invention is: the mud logging interpretation obtained by collecting data from a single wellhead in the well site does not obtain the corresponding empirical interpretation support in combination with the regional geological conditions, and cannot guarantee the accuracy of the interpretation results

Embodiment Construction
[0033] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0034] Such as figure 1 As shown, a knowledge base-based well logging interpretation method includes the following steps:
[0035] Step 1, logging in the single well logging data of a single well, and removing the garbage data in the single well logging data by means of preprocessing;
[0036] Step 2. Obtain comprehensive single well interpretation data by performing data processing and comprehensive interpretation on single well logging data;
[0037] Step 3. Taking the single well as the center, select all adjacent wells within a predetermined radius, input the adjacent well logging data of all adjacent wells, and eliminate the garbage data in the adjacent well logging data by preprocessing;
[0038] Step 4. Obt...

The invention relates to a well site logging explaining method and intelligent explaining system based on knowledge base. The explaining system includes a data input module, a data pre-processing module, a data processing module and a data output saving module. The data input module is intended for inputting single well logging data of a single well and adjoining logging data of all adjoining wells. The data pre-processing module is intended for pre-processing single-well logging data and adjoining logging data. The data processing module is intended for obtaining comprehensive single-well data and comprehensive adjoining logging data by means of data processing and comprehensive explaining. After the single-well explaining data is obtained, the adjoining wells within a well opening preset range are subject to logging explanation to obtain adjoining well logging explaining data, the single-well logging explaining data and the adjoining well logging explaining data are presented, a user can determine the accuracy of the single-well logging explaining data by comparing the single-well logging explaining data and the adjoining well logging explaining data and finding the difference therebetween, so that wrong determination caused by geology can be reduced at the maximum and the accuracy of logging explaining data can be increased.
Description
technical field [0001] The invention relates to the field of well site resource interpretation, in particular to a knowledge base-based well site logging interpretation method and an intelligent interpretation system. Background technique [0002] Interpretation and evaluation of oil, gas and water layers is an important link in oilfield exploration and development system engineering. It is an important basis for oil and gas exploration testing, production layer design, and reserve calculation. It is also an important basis for oilfield development adjustment well production perforation scheme design. In the prior art, mud logging interpretation is only performed on a single wellhead, and in different geological conditions, the same mud logging interpretation data may appear, but the final oil test result data is quite different from the single well logging interpretation, so in Mud logging interpretation for a single wellhead cannot guarantee a complete production plan data...
