Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oil exploration and development drilling engineering, and more specifically, to a method for optimizing target points while drilling based on the concept of geological engineering integration and related products. Background Art
[0002] Trajectory design is an important part of the implementation of petroleum engineering. By reasonably designing the trajectory, the difficulty of engineering implementation can be effectively reduced and the expected geological goals can be achieved. However, during the actual drilling process, due to the complexity of the formation and the influence of directional tools, there are often differences between the actual drilling trajectory and the designed trajectory. Therefore, it is necessary to continuously correct the trajectory design model during the drilling process in order to achieve a better drilling plan. During normal drilling, the wellbore trajectory can be smoothly extended to the target point while ensuring a low engineering difficulty. However, in actual drilling construction, due to the influence of the formation / instrument tools, the upper well section often cannot meet the theoretical trajectory control requirements, resulting in a significant increase in the difficulty of controlling the lower trajectory.
[0003] At present, when the spatial distance between the current trajectory point and the target point is short and the trajectory needs to be adjusted greatly, a better trajectory model is often selected for optimization from the perspective of engineering theory. However, this method has certain shortcomings: when making large trajectory adjustments in a limited spatial distance, the optimization result still has a high drilling difficulty and is difficult to effectively solve the problem.
[0004] Therefore, the present application provides a method for optimizing target points while drilling and related products based on the concept of geological and engineering integration to solve the above problems. Summary of the invention

[0027] The terms used in the various embodiments of the present application are only used for the purpose of describing specific embodiments and are not intended to limit the various embodiments of the present application. Unless otherwise specified, all terms (including technical terms and scientific terms) used herein have the same meaning as the meanings commonly understood by ordinary technicians in the field to which the various embodiments of the present application belong.

[0028] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with examples and drawings. The illustrative implementation scheme of the present application and its description are only used to explain the present application and are not intended to limit the present application.
[0029] First, some of the terms and related technologies involved in this application are explained to facilitate understanding by those skilled in the art.
[0030] 1. Well inclination is the angle between the tangent line at a point on the wellbore axis and the plumb line.
[0031] 2. Direction angle: the direction of the wellbore axis in the horizontal plane.
[0032] 3. Dip angle of the stratum is the degree of inclination of the stratum relative to the horizontal plane, usually expressed as an angle.
[0033] 4. Full angle change rate, also known as dogleg, describes the angle change of the wellbore axis in three-dimensional space within a unit well section length, including the change of well inclination and azimuth, and is usually used to measure the curvature or change speed of the wellbore. In principle, the smaller the full angle change rate, the more conducive to construction.
[0034] See also Figure 1 As shown, the present application first provides a method for optimizing the target point while drilling based on the concept of geological engineering integration. The method includes: S1, obtaining preparation data, the preparation data includes: the coordinates, well inclination angle and azimuth of the current trajectory point, as well as the coordinates of the original target point, the well inclination angle α and the azimuth angle β under geological requirements; S2, based on the original target point, assuming that the northeast coordinate or southwest coordinate of the stratum in the set spatial range has a constant inclination angle of α along the β direction, calculate the plane equation of the stratum through the original target point; S3, based on the plane equation, the plane area within the set spatial range is gridded, and each grid is regarded as an optional new target point; S4, iteratively calculate the full-angle change rate between all new target points and the current trajectory point, and select the new target point coordinates corresponding to the minimum full-angle change rate as the preferred target point coordinates.
[0035] Specifically, this scheme regards the formation dip within a certain spatial range as a constant, and calculates the plane equation passing through the original target point based on the coordinates of the original target point given by the design, with the dip angle along the β direction unchanged at α. The points on the plane can be regarded as optional new target points that meet the geological requirements; the plane is gridded, and each grid is regarded as an optional new target point; the full-angle change rate is calculated based on the coordinates, well inclination and azimuth of each new target point on the plane and the coordinates, well inclination and azimuth of the current trajectory point, and the new target point with the smallest full-angle change rate on the plane is selected as the preferred target point.
[0036] The improvement of this scheme is that, firstly, a plane equation passing through the original target point and with an inclination angle unchanged at α along the β direction is constructed to provide optional new target points that meet the geological requirements, and at the same time, the new target points that meet the geological requirements and have the smallest full-angle change rate (construction difficulty) are selected from the plane as the preferred target points through the full-angle change rate between the new target point and the current trajectory point. Secondly, the difficulty of screening is reduced by meshing the plane.
[0037] Step S1 is to obtain preparation data. Assuming that the coordinates of the original target point are (x0, y0, h0), the geology requires that the corresponding well inclination angle is α and the azimuth angle is β. The current trajectory point coordinates are (x1, y1, h1), the corresponding well inclination angle is α1, and the azimuth angle is β1.
[0038] Step S2 is to calculate the optional new target point that meets the geological requirements. Based on the original target point, assume the set spatial range of north / south coordinates x∈(x0-r1,x0+r1) and east / west coordinates y∈(y0-r2,y0+r2), r1 and r2 are the set values of the spatial range, and the formation dip angle is approximately unchanged. Then the plane equation of the formation passing through the original target point along the β direction with a constant dip angle of α is as follows:
[0039] h=tanα·cosβ·(x-x0)+tanα·sinβ·(y-y0)+h0
[0040] Among them, α is the well inclination angle under the geological requirements of the original target point, β is the azimuth angle under the geological requirements of the original target point, (x0, y0, h0) is the coordinates of the original target point, and x, y, and h are variables of the plane equation.
[0041] It can be understood that the plane corresponding to the plane equation within the set spatial range has good reservoir parameters, and any point on the plane is a new target point that can be selected from a geological perspective.
[0042] Step S3 is to reduce the difficulty of new target screening. Any point on the plane is a new target that can be selected from a geological perspective. Considering the difficulty of engineering construction, it is necessary to select the new target with the lowest construction difficulty from many new targets on the plane as the preferred target. In order to reduce the difficulty of target screening, the inventor proposes to apply grid processing to target screening. Specifically, the plane area within the set spatial range is gridded. Assuming that the length and width of each grid are 1, there are 4-1-2 solutions within the set spatial range.
[0043] Step S4 is to select the preferred target that meets the geological requirements and has the lowest construction difficulty from many optional new targets. Figure 2 As shown, it includes: S41, initializing a new target point within a set spatial range; S42, calculating the full-angle change rate between the new target point and the current trajectory point; S43, updating the new target point within the set spatial range, and repeatedly calculating the full-angle change rate between the new target point and the current trajectory point until the set spatial range is exceeded; S44, forming a full-angle change rate matrix based on the full-angle change rates between all new target points and the current trajectory point; S45, extracting the new target point coordinates corresponding to the minimum full-angle change rate from the full-angle change rate matrix as the preferred target point coordinates.
[0044] Specifically, the horizontal and vertical coordinates of the new target point are initialized within the set spatial range of x∈(x2-r1,x2+r1), y∈(y2-r2,y2+r2), and the plane equation is used to solve the vertical coordinates of the new target point to obtain the initialized coordinates of the new target point. The full-angle change rate between the new target point and the current trajectory point is calculated iteratively to reflect the difficulty of engineering implementation.
[0045] By traversing and calculating the full-angle change rate between all new target points and the current trajectory points within the set space range, the following full-angle change rate matrix can be obtained:
[0046]
[0047] Next, the new target with the smallest full-angle change rate is selected from the full-angle change rate matrix as the preferred new target. t,p , t, p are the row and column positions of the full angle change rate in the full angle change rate matrix, which also correspond to the horizontal and vertical coordinate changes of the new target within the set spatial range. Then the horizontal coordinate, vertical coordinate, and vertical coordinate of the new target corresponding to the minimum full angle change rate are x=x0-r1+t, y=y0-r2+p, and h=tanα·cosβ·(x-x0)+tanα·sinβ·(y-y0)+h0. That is, the optimal target coordinates are (x, y, h), which can be used to guide the selection of targets while drilling.
[0048] In summary, the method provided by the present invention calculates optional new targets that meet geological requirements by assuming that the inclination angle of the stratum in the set spatial range along the β direction remains unchanged at α; through grid division and full-angle change rate calculation, the new target with the smallest full-angle change rate is selected from many optional new targets as the preferred target. The preferred target not only meets the geological requirements, but also reduces the engineering implementation difficulty of the trajectory. The process of this scheme is accurate, complete, rigorous and reasonable. It combines the geological objectives and the difficulty of engineering implementation to realize the selection of drilling targets with integrated consideration of geology and engineering; the overall calculation of this scheme is simple and suitable for the selection of real-time drilling targets.
[0049] In order to explain in detail the method for optimizing target points while drilling based on the concept of geological and engineering integration provided in this application, a specific application example is provided below for illustration.
[0050] Assume that the coordinates of the original target point are (x0, y0, h0) = (3000, 3000, 3000), the inclination angle α is 30°, the azimuth angle β is 45°, when r1 = 20, r2 = 30, that is, the spatial range is set to x∈(x0-20, x0+20), y∈(y0-30, y0+30); construct the plane equation that passes through the original target point and has an inclination angle of α along the β direction:
[0051] h=tan30°·cos45°·(x-3000)+tan30°·sin45°·(y-3000)+3000.
[0052] Initialize the horizontal and vertical coordinates of the new target point to (x0-r1, y0-r2). According to the plane equation, the vertical coordinate corresponding to the new target point can be calculated as Calculate the full angle change rate between the new target point and the current trajectory point and record it as k 1,1 Similarly, we continue to iterate and calculate, assuming that xi = x0-r1+i, y j =y0-r2+j, coordinate (x i ,y j ) corresponds to a full-angle change rate k i,j , then the following full-angle change rate matrix can be obtained:
[0053]
[0054] Assume that the minimum value is k t,p =k 10,20 , then the corresponding new target coordinates are x=x0-r1+t=3000-20+10=2990, y=y0-r2+p=3000-30+20=2990, That is, the new target coordinates are (2990, 2990, 2991.835). The new target coordinates are the drilling target positions that meet both geological requirements and low construction difficulty requirements.
