Example 8
Analyzing the acquired drill bit data;
First part, data visualization.
According to the invention, labVIEW software is used, and after the acquisition unit finishes data acquisition in one period, the acquisition unit is connected with a computer to perform data visual reading by using LabVIEW. In addition to the visualization software used in the present invention, other visualization software may be used for data visualization, and specific examples of the implementation are described below. As shown in fig. 8 and 9, the group recorded data collected from the 5 month 23 day to 6 month 2 day tool.
It can be seen from the graph that the peak value, the average value and the frequency statistics of more than 5g of the axial accelerometer, the peak value, the frequency statistics of more than 5g of the lateral accelerometer, the maximum value and the minimum value of the rotating speed, the temperature and the stick-slip are collected by the tool. As seen from the graph of the average for the axial accelerometer, the average was mostly around 0, indicating that the drilling tool was in parallel vibration, the peak of the average was around 1, and the tool was in vertical vibration. Likewise, the peak value of the lateral accelerometer will vary significantly when the tool is in parallel vibration, while the tool is in vertical vibration when the peak value of the lateral acceleration is 0. The count pattern is related to the vibration frequency of the tool, and when the vibration frequency is low, a count of more than 100g is initiated.
As shown in fig. 10, from this set of data, an operation summary report can be generated in which the values of the lateral impact count and the axial impact count, the highest and lowest values of the temperature, the highest and lowest values of the rotational speed, the total recording time, the total vibration time, and the start time and end time of recording can be clearly seen by a histogram.
In addition to generating the operation report, a data document may be generated as shown in FIG. 11. The data file contains various data in the waveform chart. The data collected during the operation of the data acquisition system is shown to those skilled in the art in a more clear manner.
Second part, data depth mining
The application of artificial intelligence in data analysis is realized by using Python language, other languages and software can be used for realizing deep analysis of data besides the language used by the invention, and specific examples are not limited herein.
As shown in fig. 12, the recorder data shows the overall operation of the near bit for 31 days from 9 months 29 days to 10 months 31 days. Based on the temperature and vibration information, the downhole drilling can be easily separated from its surface transportation time period. The drill bit was started to run in the well at day 27 of 10 months 28 days after the start of the repair shop. In downhole drilling, the axial vibration peak is about 40g, the lateral vibration peak is about 180g, during surface transportation, the axial vibration peak is 27g and the lateral vibration peak is 90g for 10 months and 17 days, the lateral and axial vibration peaks are matched in time, and the rotation speed image also has fluctuation, which can be related to transportation activities or tool moving in a well site. As can be seen from the temperature and rotational speed statistics in the graph, when the near-bit is on the ground, the temperature curve shows the circadian variation law, and the rotational speed is basically 0rpm. When the near-bit is started underground, the temperature is gradually increased to 49 ℃, then the temperature is increased to about 56 ℃ when the near-bit is deeper into the stratum in the drilling process, the data acquisition system records the information of the rotating speed when the rotating drilling is started, and the situation that the single bit is required to be stopped in the drilling process or the drilling is stuck and the reversing is required to occur, so that the violent change occurs on the rotating speed image.
The analysis software further performs a statistical analysis on the data. Table 1-1 lists the operational statistics generated by the analysis tools. As shown in fig. 13a, b, c, bar graphs of statistical data are shown, including temperature, axial acceleration peak and lateral acceleration peak. From FIGS. 1-7, it can be seen that the near-bit ambient temperature analysis is at a maximum temperature of 50-60 degrees. The axial vibration is mainly concentrated in the range of +/-10 g, and the maximum vibration is 40g, but the vibration frequency is very small. It can be seen from fig. 1 to 8 that the lateral vibration is mainly concentrated at 0 to 80g, and the maximum vibration is 180g, but the number of vibrations is small.
These measurements and statistics provide valuable and abundant downhole data for near bit vibration studies. The data in the data acquisition system shown in the statistical report of the table 1-1 is clear and visual, and can help maintenance personnel and operators to quickly know the working condition of the motor so as to provide a performance improvement scheme and maintenance measures.
TABLE 1-1 statistical report
Combining the data of the data acquisition mechanism with the data of the surface equipment is shown in the figure, fig. 14 (a) shows that the motor is in a rotary drilling mode in the time period from 5:30 to 10:30, then is switched to a sliding drilling mode in the range of about 10:30, and meanwhile, the measured mud displacement of the surface is also shown in the figure. Fig. 14 (b) shows bit depth, axial vibration peak and lateral vibration peak colored according to a rotary or sliding drilling state. During rotary drilling, a high vibration intensity is observed, with lateral vibrations of about 100g and axial vibrations of about 30g. But after switching the drill bit to the sliding drilling mode, the lateral vibration is reduced to 50g and the axial vibration is reduced to 15g. Fig. 14 (c) shows the maximum, minimum and average rotational speeds. Higher stick-slip conditions were observed during the rotary drilling phase and bit stall was also observed. After switching the drill bit to the sliding drilling mode, the stick-slip is reduced.
The data acquisition system is suitable for the current requirements of domestic digital oilfield construction, an artificial intelligent algorithm is adopted to establish a model for judging the running state of equipment, a data rule is further mined, and new value is given to data. Meanwhile, an expert system is established through experience of manual analysis, evaluation of the health state of equipment is promoted, drilling efficiency is practically improved, and operation cost is reduced. On the premise of possessing a large number of data bases and successful cases, the method is combined with wear evaluation of a maintenance workshop to further establish a model of equipment service life, and achieves intelligent operation of underground equipment.
It will be appreciated that all occurrences of the drill bit during drilling are concentrated in the magnitude of vibration, rotation. Adopt the collection equipment that is independent of the drill bit can realize easy dismounting, reduce the fault rate, reduce cost's purpose to realize the intellectuality of drill bit, thereby reach following effect:
By reading various data with time marks, the running condition, faults and stratum conditions of the drill bit are known in detail, the fault rate of the drill bit during operation is reduced, and the cost is lowered.
By deep mining of different data and assisting of an intelligent algorithm, a drill bit life model is built by deep mining of data rules, and drilling efficiency is practically improved.
