Abstract
Description
Technical Field
[0001] This invention belongs to the field of petroleum engineering technology, and in particular relates to a method, system, storage medium and equipment for quantifying the similarity between actual drilling and designed wellbore trajectories. Background Technology
[0002] During the drilling process, factors such as formation dip angle, formation build-up, tool error, and operational error can cause the actual drilled wellbore trajectory to not completely correspond to the designed wellbore trajectory. Evaluating the degree of conformity between the actual drilled wellbore trajectory and the designed wellbore trajectory is crucial for the smooth construction of subsequent operations and the evaluation of drilling operation results.
[0003] Currently, the evaluation of the conformity between the actual drilled wellbore trajectory and the designed wellbore trajectory mainly relies on target hitting and whether the target well depth has been reached. However, this evaluation method uses a single evaluation index and fails to quantify the conformity between the actual drilled wellbore trajectory and the designed wellbore trajectory by combining actual drilling directional measurement data. Therefore, it cannot quickly and rationally evaluate the quality of drilling operations based on the quantified results. Consequently, the evaluation accuracy is low. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0058] See appendix Figure 1 The method of the present invention includes:
[0059] S1. Collect actual drilling and design wellbore trajectory data of the target well;
[0060] The wellbore trajectory data includes:
[0061] Wellhead location coordinates, endpoint location coordinates, rotary table height, well depth, target point allowable radius, and other measuring point data.
[0062] S2. Based on the wellbore trajectory data, calculate the deviation component of the actual drilled wellbore trajectory relative to the designed wellbore trajectory;
[0063] The deviation component of the actual drilled wellbore trajectory from the designed wellbore trajectory includes:
[0064] Wellhead coordinate deviation, target point deviation, endpoint coordinate deviation, and other total point coordinate deviations.
[0065] The formula for calculating the wellhead coordinate deviation is as follows:
[0066]
[0067] Among them, S h X represents the wellhead coordinate deviation. hD Y hD KB hD These represent the design wellhead's east and north coordinates, as well as the rotary table height, in meters; X hA Y hA KB hA These represent the east and north coordinates of the actual drilled wellhead and the height of the rotary table, in meters; H represents the designed maximum well depth for the target well section, in meters.
[0068] The formula for calculating the target deviation is as follows:
[0069]
[0070] Among them, S T r represents the target deviation. D r AThese are the maximum allowable target radius (design) and the actual drilled target radius (in meters).
[0071] The deviation of the coordinates of the remaining total points is the average value of the deviation of the coordinates of the remaining measuring points.
[0072] S3. Based on the deviation component, calculate the trajectory offset.
[0073] The trajectory offset is calculated by summing the deviation components.
[0074] Specifically,
[0075] I. Data Collection.
[0076] Collect actual drilled wellbore trajectory data and designed wellbore trajectory data of the target well.
[0077] The wellbore trajectory data includes: wellhead location coordinates, endpoint location coordinates, rotary table height, well depth, target point allowable radius, and other measuring point data.
[0078] II. Calculate the deviation component.
[0079] Based on the wellbore trajectory data, the deviation component of the actual drilled wellbore trajectory relative to the designed wellbore trajectory is calculated.
[0080] The deviation components include: wellhead coordinate deviation, target point deviation, endpoint coordinate deviation, and other total point coordinate deviations.
[0081] 1. Wellhead coordinate deviation.
[0082] The wellhead coordinate deviation represents the degree of deviation between the designed wellhead position and the actual drilled wellhead position. The wellhead coordinate deviation is calculated based on the designed wellhead position coordinates, the actual drilled wellhead position coordinates, the rotary table height, and the well depth.
[0083] Wellhead coordinate deviation is defined as the degree of deviation between the designed wellhead position and the actual drilled wellhead position. The actual drilled wellhead position generally refers to the position of the rotary table. During the actual drilling process, due to factors such as well site construction and measurement deviations, there will be a deviation between the designed wellhead position and the actual drilled wellhead position. The wellhead coordinate deviation is calculated according to formula (1):
[0084]
[0085] Among them, S h X represents the wellhead coordinate deviation. hD Y hD KB hD These represent the design wellhead's east and north coordinates, as well as the rotary table height, in meters; X hA Y hA KBhA These represent the east and north coordinates of the actual drilled wellhead and the height of the rotary table, in meters; H represents the designed maximum well depth of the target well section, in meters.
[0086] In this embodiment, the east and north coordinates of the wellhead are used to represent the location of the wellhead.
[0087] 2. Target deviation.
[0088] The target deviation is the ratio of the actual drilled target radius to the maximum allowable target radius. If there are multiple target points, the average deviation of all target points is taken as the target deviation of the entire trajectory.
[0089] The target deviation is defined as the ratio of the actual drilled target radius to the maximum allowable target radius. If there are multiple targets, the average of all target deviations is taken as the target deviation of the overall trajectory.
[0090] Calculate the target deviation according to formula (2):
[0091]
[0092] Among them, S T r represents the target deviation. D r A These are the maximum allowable target radius and the actual drilled target radius, respectively, in meters (m).
[0093] 3. Deviation of endpoint coordinates.
[0094] The endpoint coordinate deviation is the degree of deviation between the designed endpoint position and the actual drilling endpoint position. The endpoint coordinate deviation is calculated based on the designed endpoint position coordinates, the actual drilling endpoint position coordinates, and the well depth.
[0095] The endpoint coordinate deviation is defined as the degree of deviation between the designed endpoint position and the actual drilling endpoint position. The endpoint coordinate deviation is calculated according to formula (3):
[0096]
[0097] Among them, S N X represents the deviation of the endpoint coordinates. ND Y ND TH ND These represent the design endpoint's east and north coordinates and well depth, in meters; x NA Y NA TH NA These represent the east and north coordinates of the actual drilling endpoint and the well depth, respectively, in meters; H represents the designed maximum well depth of the target well section, in meters.
[0098] 4. Deviation of coordinates of other total points.
[0099] The deviation of the coordinates of the remaining total points is the average of the deviations of the coordinates of the remaining measuring points.
[0100] The remaining measuring points are defined as all measuring points other than the wellhead, endpoint, and target point. In this embodiment, during the drilling process, single-point or multi-point inclination measurement operations are performed on the wellbore trajectory, and multiple measuring points will form a set, which is defined as the remaining measuring points.
[0101] In this embodiment, multiple coordinate systems can be used to describe the wellbore trajectory, such as: east coordinate-north coordinate-depth, or well depth-well inclination-azimuth, etc.
[0102] If the East-North-Depth coordinate system is adopted, it is preferable to use the well depth as the reference to calculate the deviation of the coordinates of the remaining total points. The deviation of the coordinates of the remaining total points is calculated according to formula (4):
[0103]
[0104] Among them, S D S represents the deviation of the coordinates of the remaining total points; Di The remaining single-point coordinate deviation; n is the total number of measuring points;
[0105] H D H A These are the designed well depth and the actual well depth along the drilled well trajectory, respectively, under the same east and north coordinate conditions, in meters; H max The design depth is the maximum depth for the target well section, in meters. In actual calculations, the east and north coordinates of the measuring point should be used as a reference, and the corresponding well depths for the same east and north coordinates should be calculated from the designed wellbore trajectory.
[0106] In the East-North-Depth coordinate system, the deviation of the coordinates of the remaining total points can also be calculated using the East coordinate as the reference, according to formula (4):
[0107]
[0108] in, X D X A These are the designed east coordinates and the east coordinates on the actual drilled wellbore trajectory, respectively, under the same well depth and north coordinate conditions, in meters; X max The design value is the maximum absolute value of the eastern coordinate of the target well section, in meters. In actual calculations, the well depth and northern coordinate at the measuring point should be used as a reference, and the eastern coordinate corresponding to the same well depth and northern coordinate should be calculated from the designed wellbore trajectory.
[0109] In the East-North-Depth coordinate system, the deviation of the coordinates of the remaining total points can also be calculated using the North coordinate as the reference, according to formula (4):
[0110]
[0111] in, Y D Y A These are the designed north coordinates and the north coordinates on the actual drilled wellbore trajectory, respectively, under the same well depth and east coordinate conditions, in meters; Y max The design value is the absolute value of the maximum north coordinate for the target well section, in meters. In actual calculations, the well depth and east coordinate at the measuring point should be used as a reference, and the north coordinate corresponding to the same well depth and east coordinate should be calculated from the designed wellbore trajectory.
[0112] In this embodiment, if a well depth-inclination-azimuth coordinate system is used, the deviation of the coordinates of the remaining total points is calculated according to formula (4):
[0113]
[0114] in, INC D INC A These are the designed well inclination angle and the well inclination angle on the actual drilled well trajectory, respectively, under the same depth and azimuth conditions, in degrees; INC max The maximum well inclination angle is designed for the target well section, in degrees. In actual calculations, the well depth and azimuth at the measuring point should be used as a reference, and the well inclination angle corresponding to the same well depth and azimuth should be calculated inversely from the designed wellbore trajectory.
[0115] III. Calculate the trajectory offset.
[0116] The trajectory offset is calculated based on the deviation components, and the degree of deviation of the actual drilling trajectory from the designed trajectory is determined based on the trajectory offset. All deviation components are summed to obtain the trajectory offset, i.e., trajectory offset S = wellhead coordinate deviation S. h +Target deviation S T +Destination coordinate deviation S N + Deviation of other total points S D .
[0117] The larger the trajectory offset value, the greater the difference between the actual drilling trajectory and the designed trajectory, and the lower the similarity. By calculating the trajectory offset, the similarity between the actual drilled well trajectory and the designed well trajectory can be quantified. Based on the trajectory offset value, a direct and accurate evaluation of the similarity between the actual drilled well trajectory and the designed well trajectory of the target well can be made, allowing for a rational evaluation of the drilling operation quality.
[0118] The quantitative evaluation of the entire well section or any section of the target well can be carried out using the quantification method of the similarity between the actual drilling and the designed wellbore trajectory in this embodiment.
[0119] In this embodiment, directional well XX in oilfield A is used as an example for illustration.
[0120] In Oilfield A, there is a directional well XX with a designed depth of 2000m. The designed wellbore trajectory and the actual drilled wellbore trajectory data are shown in Table 1. There is also a directional well YY with a known trajectory deviation of 0.1. Based on the designed wellbore trajectory and the actual drilled wellbore trajectory data of well XX, the deviation between the actual drilled wellbore trajectory and the designed wellbore trajectory of well XX can be calculated, and then the directional well XX and directional well YY can be quantitatively evaluated.
[0121] Table 1
[0122]
[0123] Based on the parameters in Table 1, the following can be calculated:
[0124] Wellhead coordinate deviation:
[0125]
[0126] End point coordinate deviation:
[0127]
[0128] Target deviation:
[0129]
[0130] Target deviation 2:
[0131]
[0132] Total target deviation:
[0133]
[0134] During the actual drilling of Well XX, 32 points were measured. The measurement coordinate system adopted was the East-North-Well-Depth Coordinate System. The measured wellbore trajectory data is shown in Table 2. The deviation of the remaining total points was calculated based on the well depth.
[0135] Table 2
[0136]
[0137]
[0138] Based on the east and north coordinates of the actual drilling trajectory data in Table 2, and combined with the design trajectory data, the design well depth and single-point coordinate deviation of each measuring point can be calculated. The calculation results are shown in Table 3.
[0139]
[0140]
[0141] Based on the data in Tables 2 and 3, the deviation S of the coordinates of the remaining total points can be calculated. D It is 0.04.
[0142] Calculate the trajectory offset based on the aforementioned deviation components:
[0143] Trajectory offset S = Wellhead coordinate deviation S h +Target deviation S T +Destination coordinate deviation S N + Deviation of other total points S D
[0144] The trajectory offset S = 0.045 + 0.043 + 0.35 + 0.04 = 0.478
[0145] The directional well XX and the directional well YY were quantitatively evaluated based on the trajectory deviation. The trajectory deviations of well YY and well YY were compared. Since the trajectory deviation of well YY was 0.1, the actual drilling trajectory of well YY was more consistent with the design trajectory than that of well XX.
