Description

Technical Field

[0001] The present invention relates to the technical field of oil drilling, and in particular to a real-time working condition identification method and device for sitting and connecting single roots during a drilling process. Background Art

[0002] During drilling operations, the drill pipe is placed into the slips to prevent it from falling into the well during connection. Therefore, accurately determining the state of the slip is crucial. Furthermore, accurate identification of the state of the slip is essential for real-time monitoring of the connection process, thus enabling precise steerable drilling operations.

[0003] Existing methods for identifying stuck conditions mostly rely on setting a hook load threshold. In practice, drillers must use hook load sensors to detect changes in hook load and manually set the appropriate threshold. This method relies on the performance of the hook load sensor and requires cumbersome manual operation. Furthermore, because the weight of the drill string and a single drill string in the upper well section is not significantly different, identifying the stuck state and the single drill string connection based on changes in hook load is difficult in practice. In other words, existing methods for identifying stuck conditions are not suitable for shallow well sections. Summary of the Invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0040] Figure 1 This is a flowchart of a first embodiment of a method for real-time working condition identification for drilling process positioning and connection;

[0041] Figure 2 This is a structural block diagram of an embodiment of a real-time working condition identification device for sitting and connecting single roots during drilling. DETAILED DESCRIPTION

[0042] The embodiment of the present invention provides a method and device for real-time working condition identification of drilling clamping and single-thread connection, which is used to identify the real-time working conditions of drilling clamping and single-thread connection operations in real time and improve drilling operation efficiency.

[0043] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] For example 1, please refer to Figure 1 , Figure 1 This is a flowchart of an embodiment of a method for real-time working condition identification of a well during drilling and connection, specifically including:

[0045] S1, obtain the real-time drill bit position, drill bit depth and single-joint operation information during the drilling operation;

[0046] S2, determining whether the real-time drill depth is less than a preset drill depth threshold; if not, executing step S3; if so, executing step S4;

[0047] S3, determining whether the single root in the single root connection operation information is the first single root; if so, executing step S4; if not, executing step S5;

[0048] S4, using the hook load standard deviation criterion, determines the real-time working conditions of the sitting card and the single-bar connection;

[0049] Specifically include:

[0050] If at each time step t c If the hook load standard deviation in the time window T is greater than the hook load threshold of the previous single log, and the difference between the hook load average values ​​of the first T / 3 window and the last T / 3 window is greater than the hook load threshold of the previous single log, then the real-time working condition of the sitting card and the connecting log is determined to be the sitting slip state;

[0051] If at each time step t c If the standard deviation of the hook load in the time window T is greater than the hook load threshold of the previous single root, and the difference between the average hook load values ​​of the first T / 3 window and the last T / 3 window is less than the hook load threshold of the previous single root, it is determined that the real-time working condition is the slip removal state.

[0052] It's important to note that the hook load standard deviation criterion is a method used to assess the degree of dispersion in hook load data and thus determine the operating status of the drilling rig. Specifically, the hook load standard deviation criterion determines hook load fluctuation by calculating the standard deviation of the hook load data within a specific time window. The standard deviation measures the difference between the hook load data and its mean. When the standard deviation of the hook load data exceeds a set threshold, it indicates significant hook load fluctuation and possible anomalies.

[0053] Time step t c Refers to the length of each time interval in hook load data analysis. It is usually expressed in seconds and is used for real-time monitoring and analysis of hook load data.

[0054] The hook load threshold can be determined empirically or based on historical data analysis. Hook load data from drilling operations can be statistically analyzed to calculate the standard deviation and mean hook load, thereby determining appropriate thresholds for determining slip engagement and slip removal.

[0055] The hook load standard deviation is a statistic that measures the degree of variation in the hook load data within a given time window. By calculating the standard deviation of the hook load data within a buffer, the volatility and stability of the hook load data can be measured.

[0056] Average hook load refers to the average hook load over a period of time. In drilling operations, hook load refers to the force or weight exerted on a lifting machine (such as a drilling rig) when suspending materials or cargo. Average hook load is often used to describe the level of hook load over a specific period of time.

[0057] In an embodiment of the present invention, if the drill bit depth is less than the set depth, or the drill bit depth is greater than the set depth and it is the first single drill bit, the hook load standard deviation criterion is adopted.

[0058] In the specific implementation, at each time step t cIf the hook load standard deviation in the time window T, that is, the T-second buffer area, is greater than the hook load threshold of the previous single piece, and the difference between the average hook load values ​​of the first T / 3 window and the last T / 3 window is greater than the hook load threshold of the previous single piece, then it is recorded as the state of being in the slip. If the hook load standard deviation in the T-second buffer area is greater than the hook load threshold of the previous single piece, and the difference between the average hook load values ​​of the first T / 3 window and the last T / 3 window is less than the hook load threshold of the previous single piece, then it is recorded as the state of being out of the slip.

[0059] S5, using a dynamic hook load threshold criterion, determining the real-time working conditions of the sitting card and the single log connection;

[0060] Specifically include:

[0061] If at each time step t c If the average hook load value in the time window T is greater than the hook load threshold value of the previous single log, and the average hook load value in the first T / 3 window is greater than the hook load threshold value of the previous single log, and the average hook load value in the last T / 3 window is less than the hook load threshold value of the previous single log, then the real-time operating condition is determined to be the sitting slip state, and when a single log is connected, the hook load threshold value is updated using the threshold update expression;

[0062] If at each time step t c If the average hook load value in the time window T is greater than the hook load threshold of the previous single root, and the average hook load value of the first T / 3 window and the average hook load value of the first T / 3 window are less than the hook load threshold of the previous single root, and the average hook load value of the last T / 3 window is greater than the hook load threshold of the previous single root, then the real-time working condition is determined to be the slip-lifting state, and when a single root is connected, the hook load threshold is updated by the threshold update expression.

[0063] Specifically, the threshold update expression is:

[0064] Th new =HKLD low +0.25(HKLD high -HKLD low );

[0065] Among them, Th new Hook load threshold set for next recognition, HKLD low The average hook load value in the first T / 3 window when drilling, HKLD high It is the average value of the hook load in the first T / 3 window when drilling down.

[0066] It's important to note that the dynamic hook load threshold criterion dynamically adjusts the hook load threshold based on real-time data. This is used to assess hook load status and detect potential anomalies. Based on the characteristics and trends of real-time data, the dynamic hook load threshold criterion adaptively updates the threshold through an algorithm or model, resulting in a more accurate assessment of hook load status.

[0067] In an embodiment of the present invention, if the drill bit depth is greater than a set depth and it is not the first single drill bit, a dynamic hook load threshold criterion is adopted.

[0068] In the specific implementation, at each time step t c If the average hook load value in the T-second buffer is greater than the hook load threshold of the previous single log, and the average hook load value in the first T / 3 window is greater than the hook load threshold of the previous single log, and the average hook load value in the last T / 3 window is less than the hook load threshold of the previous single log, then it is recorded as the state of being in the slips. If the average hook load value in the T-second buffer is greater than the hook load threshold of the previous single log, and the average hook load value in the first T / 3 and last T / 3 windows is less than the hook load threshold of the previous single log, and the average hook load value in the last T / 3 window is greater than the hook load threshold of the previous single log, then it is recorded as the state of being out of the slips.

[0069] Additionally, if the drilling operation is in the "joining" state, the hook load threshold can be updated using a threshold update expression to identify the next drilling process, such as when the well is stuck or when a joint is being made. Whether a joint is being made can be inferred by comparing the drill bit position during the downhole state.

[0070] In an embodiment of the present invention, a method for identifying the real-time working conditions of the drilling process during the sitting and connecting of single roots is provided. Through S1, the real-time drill bit position, drill bit depth and single root connection operation information of the drilling process are obtained; S2, whether the real-time drill bit depth is less than a preset drill bit depth threshold is determined; if not, step S3 is executed; if so, step S4 is executed; S3, whether the single root in the single root connection operation information is the first single root; if so, step S4 is executed; if not, step S5 is executed; S4, the real-time working conditions of the sitting and connecting of single roots are determined using the hook load standard deviation criterion; S5, the real-time working conditions of the sitting and connecting of single roots are determined using the dynamic hook load threshold criterion. Based on the hook load standard deviation criterion and the dynamic hook load threshold criterion, the hook load threshold is automatically determined, and the real-time working conditions of the sitting and connecting of single roots in the entire well section of the drilling project are identified in real time, thereby improving the efficiency of the drilling operation.
