Description
Technical Field
The invention relates to the field of oil and gas well drilling, in particular to a method and a device for determining a drilling well site and a computer readable storage medium.
Background
Before drilling the oil and gas well, the drilling well site of the oil and gas well needs to be determined in advance, so that the drilling of the oil and gas well is realized at the determined drilling well site. Due to the restrictions of surface conditions, and increasingly stringent environmental requirements, the use of drilling sites is becoming increasingly tight. Therefore, more and more areas are drilled in a cluster well manner to achieve the purpose of saving land. The cluster well is a well site or platform, and is characterized in that a plurality of wells or even hundreds of wells are drilled, the well mouths of the wells are spaced by less than several meters, and the well bottoms of the wells extend to different directions. When a drilling well site is determined for a cluster well, the contents of the well site position, the well row direction, the well site size and the like are mainly determined. Wherein, the well row is formed by the well heads of a plurality of oil and gas wells which are positioned on the same straight line.
At present, drilling well sites of cluster wells are generally designed in an earth surface area above a target point so as to reduce the drilling footage of oil and gas wells, reduce the construction difficulty and the like. The target point refers to a preset coordinate point to which a drilling track of the oil and gas well extends in the drilling process. However, when the target is located in an environmentally sensitive area, such as a shallow sea, a lake, a wetland, a reservoir, etc., a drilling well site cannot be built above the target due to the influence of environmental or economic factors. Therefore, in order to perform the drilling of the oil and gas well in the environment sensitive area, a method for determining the drilling field is needed, so as to construct the drilling field based on the shoreline of the environment sensitive area. Wherein, the shoreline refers to the water-land boundary line of the environment sensitive area.

FIG. 2 is a schematic flow chart of a method for determining a drilling site in accordance with an embodiment of the present invention. Referring to fig. 2, the method includes the following steps.
When the target point of each oil and gas well in the multiple oil and gas wells is located in the target environment sensitive area, due to the influence of environmental protection factors or economic factors, the drilling well site where the multiple oil and gas wells are located can be determined on the other side of a shoreline of the target environment sensitive area on the basis of the shoreline. When the drilling well site is determined, in order to avoid large distance between the drilling well site and the multiple oil and gas wells, the position coordinates of the gravity centers of the target points of the multiple oil and gas wells can be determined in advance, and then a straight line where a shore line of the target environment sensitive area is located can be determined. The target environment sensitive area refers to an environment sensitive area where a target point of the multi-port oil gas is located, and the shoreline refers to a land-water boundary line of the target environment sensitive area.
Specifically, the position coordinates of the center of gravity of the target point of the plurality of oil and gas wells and the straight line where the shore line of the target environment sensitive area is located can be determined through the following steps 201 to 203.
Step 201: and acquiring the position coordinates of the target point of each oil and gas well in the plurality of oil and gas wells, the position coordinates of any point on the shore line of the target environment sensitive area, and the included angle between the shore line and the orthoeast direction or the orthonorth direction.
For the position coordinates of the center of gravity of the target point of the plurality of oil and gas wells, the center of gravity of the target point of the plurality of oil and gas wells refers to the center position of the target point of the plurality of oil and gas wells, so that the position coordinates of the target point of each oil and gas well in the plurality of oil and gas wells can be obtained when the position coordinates of the center of gravity of the target point of the plurality of oil and gas wells are determined. For example, when the plurality of oil and gas wells include 10 oil and gas wells, the position coordinates of the target point of each of the 10 oil and gas wells can be obtained by the following table 1.
TABLE 1
For the shore line of the target environment sensitive area, the equation of the shore line of the target environment sensitive area can be determined based on a point-diagonal equation of a straight line, namely, the equation can be determined based on the position coordinate of any point on the shore line and the included angle between the shore line and the east direction or the north direction. Therefore, before determining the straight line where the shoreline is located, the position coordinate of any point on the shoreline and the included angle between the shoreline and the true east direction or the true north direction can also be obtained. For example, the coordinate of any point on the shore line is (20558000, 4267100), and the included angle between the shore line and the true north direction is 9.46 °.
Of course, when determining the straight line on which the shoreline is located, the straight line on which the shoreline is located may also be determined by other methods, for example, the straight line on which the shoreline is located may be determined based on the position coordinates of any two points on the shoreline. Before the straight line where the shoreline is located is determined through the position coordinates of any two points on the shoreline, the position coordinates of any two points on the shoreline can be obtained.
When the drilling well site of the multiple oil and gas wells is determined, a rectangular coordinate system can be established by taking the orthodontist direction as an x axis and the orthodontist direction as a y axis. Of course, a rectangular coordinate system may also be established with the due north direction as the x-axis and the due east direction as the y-axis, which is not limited in the embodiment of the present invention.
Step 202: and determining the position coordinates of the gravity centers of the target points of the plurality of oil and gas wells based on the position coordinates of the target point of each oil and gas well.
Specifically, based on the abscissa of the target point of each oil and gas well, the abscissas of the gravity centers of the target points of the multiple oil and gas wells are determined according to the following formula (1); and (3) determining the vertical coordinate of the gravity center of the target points of the plurality of oil and gas wells according to the following formula (2) based on the vertical coordinate of the target point of each oil and gas well.
Wherein, in the above formula (1), XpRefers to the abscissa of the gravity center of the target point, N refers to the number of the target points, i refers to the ith target point, and xiRefers to the abscissa of the ith target point; in the above formula (2), YpMeans the ordinate of the gravity center of the target point, N means the number of the target points, i means the ith target point, yiRefers to the ordinate of the ith target point.
Continuing with the above example, for the coordinates of the target point of each of the 10 hydrocarbon wells, the abscissa of the center of gravity of the target point of the 10 hydrocarbon wells is determined to be 20558650 according to the above formula (1), and the ordinate of the center of gravity of the target point of the 10 hydrocarbon wells is determined to be 4268000 according to the above formula (2), that is, the coordinates of the center of gravity of the target point of the 10 hydrocarbon wells are (20558650, 4268000).
Step 203: and determining the straight line where the shoreline is located based on the position coordinate of any point on the shoreline and the included angle.
Specifically, when the included angle between the shore line and the due north direction is obtained, the straight line where the shore line is located may be determined according to the following formula (3) based on the position coordinate of any point C on the shore line and the included angle; when the included angle between the shoreline and the east-ward direction is obtained, the straight line where the shoreline is located may be determined according to the following formula (4) based on the position coordinate of any point C on the shoreline and the included angle.
Y1＝cotα×X1+Yc-cotα×Xc (3)
Y1＝tanα×X1+Yc-tanα×Xc (4)
Wherein, in the above formula (3), Y1Is the ordinate, X, of any point on the straight line on which the shoreline is located1Is the abscissa corresponding to the ordinate of any point on the straight line where the shoreline is located, alpha is the included angle between the shoreline and the due north direction, and Y is the included angle between the shoreline and the due north directioncRefers to the ordinate, X, of any point CcRefers to the abscissa of any point C; in the above formula (4), α is an angle between the shore line and the east direction, and the meanings of the other parameters may be the meanings of the corresponding parameters in the above formula (3).
Continuing with the above example, when the obtained position coordinate of any point C on the shoreline is (20558000, 4267100), the included angle between the shoreline and the due north direction is 9.46 °, and the straight line where the shoreline is located is determined to be Y according to the above formula (3)1＝6×X1-119080900。
Step 204: and acquiring the minimum safety distance between the drilling well site where the plurality of oil and gas wells are located and the shore line, and well site parameters of the drilling well site.
For the minimum safe distance between the drilling well site and the shore line, after the position coordinates of the gravity centers of the target points of the multiple oil and gas wells and the straight line where the shore line is located are determined, in order to avoid potential safety hazards of the determined drilling well site due to the target environment sensitive area and avoid that the drilling well site is far away from the target point of each oil and gas well, so that the drilling cost of the oil and gas wells is increased, the minimum safe distance between the drilling well site where the multiple oil and gas wells are located and the shore line can be obtained.
For example, the minimum safe distance between the drilling well site and the shore line may be 15 meters.
For the well site parameters of the drilling well site, before the drilling of the plurality of oil and gas wells, the drilling well site needs to be provided with a plurality of drilling devices, and moving channels of the plurality of drilling devices need to be reserved. Because the area occupied by each of the plurality of drilling equipment may vary, wellsite parameters for the plurality of wells may be obtained prior to determining the drilling wellsite for the plurality of wells.
The well site parameters can include the area range occupied by each of the plurality of drilling equipment, the annular well site road width of the drilling well site, the number of well heads of the oil and gas wells and the interwell distance between any two adjacent oil and gas wells. The area range occupied by each drilling device can comprise the area range occupied by the drilling device from a wellhead to a gate direction of a drilling well site, the area range occupied by the drilling device from the wellhead to a background direction of the drilling well site, the area range occupied by the drilling device from the wellhead of the most edge oil and gas well to two sides, the area range occupied by the drilling device, the area range occupied by the drilling matching device and the like. The number of the well heads of the oil and gas wells can be set according to 1.2-1.5 times of the number of the target spots.
For example, each of the plurality of drilling apparatuses may occupy an area ranging from: the minimum distance from a wellhead to a gate direction of a drilling well site of the drilling rig equipment is 40 meters, the minimum distance from the wellhead to a background direction of the drilling well site of the drilling rig equipment is 30 meters, the minimum distance from the wellhead to two sides of the most edge oil and gas wells of the drilling rig equipment is 10 meters, the minimum range required by the drilling rig equipment is 30 multiplied by 10 square meters, the minimum range required by drilling corollary equipment is 30 multiplied by 15 square meters, the width of a well site surrounding road of the drilling well site is 3 meters, the number of wellheads of the oil and gas wells is 14, and the well spacing between any two adjacent oil and gas wells is 6 meters.
After the minimum safe distance between the drilling well site and the shore line and well site parameters of the drilling well site are obtained, the straight line where the well row formed by the well heads of the multiple oil and gas wells is located can be determined based on the position coordinates of the gravity center of the target point, the straight line where the shore line is located, the minimum safe distance and the well site parameters. Specifically, this can be achieved by steps 205 to 206 as follows.
Step 205: and determining the central point of the wellhead of the multi-wellhead oil and gas well in the direction which passes through the position coordinate of the gravity center of the target point and is perpendicular to the straight line of the shoreline based on the straight line of the shoreline, the minimum safety distance and the well site parameters.
In order to meet the area range occupied by drilling equipment in a drilling well site and avoid potential safety hazards brought to the drilling well site by a target environment sensitive area, and meanwhile, in order to avoid the situation that the distance between the well mouth of each oil and gas well in the multiple oil and gas wells is far from the corresponding target point, so that the investment cost of drilling the oil and gas wells is increased, the central point of the well mouth of the multiple oil and gas wells can be determined on the basis of the minimum safety distance between the shore line and the drilling well site, the annular well site road width of the drilling well site and the area range occupied by the drilling equipment in the gate direction from the well mouth to the drilling well site or the area range occupied by the drilling equipment in the background direction from the well mouth to the drilling well site in the direction which passes through the position coordinates of the center of the target point and is perpendicular to the shore line.
In a possible implementation manner, based on the position coordinate of the center of gravity of the target point and the included angle between the straight line where the shore line is located and the due north direction, the straight line where the direction perpendicular to the straight line where the shore line is located is determined according to the following formula (5), and then the position coordinate of the intersection point B between the straight line where the direction perpendicular to the straight line where the shore line is located and the straight line where the shore line is located is determined. And then, determining the distance between the intersection point B and the central point A based on the minimum safety distance between the shore line and the drilling well site, the annular well site road width of the drilling well site and the occupied area range of the drilling equipment from the wellhead to the gate direction of the drilling well site or the occupied area range of the drilling equipment from the wellhead to the background direction of the drilling well site, wherein the well site parameters comprise, and further determining the position coordinate of the central point A according to the following formula (6) based on the straight line perpendicular to the direction of the shore line and the position coordinate of the intersection point B and the distance between the intersection point B and the central point A.
Y2＝-tanα×X2+Yp+tanα×Xp (5)
Wherein, in the above formula (5), Y2Is a square perpendicular to the straight line of the shorelineTo the ordinate, X, of any point on the line in which it lies2Is the abscissa, Y, corresponding to the ordinate of any point on the straight line in the direction perpendicular to the straight line on which the shoreline is locatedpRefers to the ordinate, X, of the center of gravity of the target pointpThe horizontal coordinate of the gravity center of the target point is shown, and alpha is an included angle between the shore line and the due north direction; in the above formula (6), YaIs the ordinate, X, of the center point AaIs the abscissa, Y, of the center point AbIs the ordinate, X, of the point of intersection BbThe horizontal coordinate of the central point B is defined, the L is the distance between the central point A and the intersection point B, and the meanings of the rest parameters are the meanings of the corresponding parameters of the formula (5).
Continuing with the above example, if the included angle between the shore line and the due north direction is 9.46 °, the position coordinate of the center of gravity of the target point is (20558650, 4268000), and the straight line perpendicular to the direction of the shore line is determined to be (i.e. the straight line perpendicular to the direction of the shore line is) based on the above formula (5)
Further passes through the straight line Y where the shoreline is positioned1＝6×X1-119080900 line extending from a direction perpendicular to the line on which the shore line extends
The coordinates of the intersection point B are determined to be (20558163, 4268081). Thereafter, based on the minimum safe distance of 15 meters, the minimum distance of 30 meters of rig equipment from the wellhead to the background direction of the drilling site, and the link-to-site road width of 3 meters, the distance between intersection point B and center point L is determined to be 48 meters. Further, the position coordinates of the center point a are determined to be (20558116, 4268089) according to the above formula (6).
Step 206: and determining the straight line where the well is arranged based on the straight line where the central point and the shore line are located.
After the well head central points of the multiple oil and gas wells are determined, in order to ensure that each oil and gas well in the multiple oil and gas wells has no potential safety hazard and ensure that the drilling track of each oil and gas well is shortest, parallel lines parallel to the straight line where the shoreline is located can be made through the central points, and the straight lines where the parallel lines are located are determined as the straight lines where the well rows of the multiple oil and gas wells are located.
Continuing with the above example, the position coordinate of the center point A is (20558116, 4268089), and the straight line of the shore line is Y1＝6×X1119080900, determining the straight line Y on which the well is arranged based on the position coordinates of the center point A and the straight line on which the shore line is arranged3＝6×X3-119080607。
After determining the line of the well row, i.e., the location and the direction of the well row, the location and the size of the wellsite of the drilling wellsite can be determined by a minimum area method based on the line of the well row and the wellsite parameters. Specifically, this can be achieved by steps 207 to 208 as follows.
Step 207: and determining the well mouth position of each oil and gas well by the method of the minimum connecting line distance between the well mouth of the plurality of oil and gas wells and the corresponding target point based on the straight line where the well is arranged, the position coordinates of the target point of each oil and gas well in the plurality of oil and gas wells and the well-to-well distance between any two adjacent oil and gas wells included in the well field parameters.
When the well head positions of the plurality of oil and gas wells are on the straight line where the well row is located, the well head positions can be determined on the straight line where the well row is located on the basis of the obtained inter-well distance between any two adjacent oil and gas wells. When the well head position of each oil and gas well is determined on the straight line where the wells are arranged, in order to ensure that the sum of the drilling tracks of each oil and gas well is minimum so as to reduce the investment cost of the plurality of oil and gas wells, and on the basis of the preset geological constraint condition, the well head position of each oil and gas well can be determined by the method of minimizing the connecting line distance between the well head of the plurality of oil and gas wells and the corresponding target point.
The preset geological constraint condition may be preset based on the exploitation range or the ground limitation condition of the multiple oil and gas wells, for example, the preset geological constraint condition may be an abscissa range or an ordinate range of a position coordinate of a wellhead position of any one of the multiple oil and gas wells.
Step 208: and determining the well site position and the well site size of the drilling well site through a minimum area method based on the wellhead position of each oil and gas well and the well site parameters.
Specifically, after determining the wellhead position of each of the plurality of oil and gas wells in the drilling well field, the length occupied by the well rows of the plurality of oil and gas wells in the drilling well field can be determined based on the wellhead number of the oil and gas wells included in the well field parameters. And on the basis of the area occupied by the well row, determining the length and the width of the drilling area in the drilling well site based on the area range occupied by the drilling equipment from the wellhead to the gate direction of the drilling well site, the area range occupied by the drilling equipment from the wellhead to the background direction of the drilling well site and the area range occupied by the drilling equipment from the wellhead to the two sides of the most edge oil and gas well. Then, based on the length and the width of the drilling area, the length and the width of the drilling well site are determined based on the area occupied by the drilling equipment, the area occupied by the drilling corollary equipment and the annular well site road width of the drilling well site, wherein the well site parameters comprise the area occupied by the drilling equipment, the area occupied by the drilling corollary equipment and the annular well site road width of the drilling well site. After the length and the width of the drilling well site are determined, based on the position coordinates of the wellhead position of any one of the multiple oil and gas wells, the distance between the four side lines of the oil and gas well from the drilling well site and the included angle between the shore line and the due north direction, which are determined in the step 207, the straight lines where the four side lines of the drilling well site are respectively located are determined in a point-skew manner, and then the position coordinates of the four corners of the drilling well site are determined through the intersection point between any two straight lines of the four straight lines.
Wherein the drilling field may have a rectangular configuration, and the area of the drilling field may be determined by a product between a length and a width of the drilling field.
Continuing the above example, the plurality of oil and gas wells include 14 oil and gas wells, and if the distance between the well heads of any two adjacent oil and gas wells is 6 meters, the length occupied by the well bank is (14-1) × 6 meters, that is, the length occupied by the well bank is 78 meters. Because the minimum distance from the wellhead to the gate direction of the drilling well site of the drilling rig is 40 meters, the minimum distance from the wellhead to the background direction of the drilling well site of the drilling rig is 30 meters, the minimum distance from the wellhead to both sides of the most edge oil and gas well of the drilling rig is 10 meters, the length of the drilling area of the drilling well site is the sum of the length of a well row of 78 meters and the minimum distance from the wellhead to both sides of the drilling rig from the wellhead of the most edge oil and gas well, namely the length of the drilling area is 98 meters, the width of the drilling area is 40 meters, the minimum distance from the wellhead to the gate direction of the drilling well site of the drilling rig is the sum of 30 meters, namely the width of the drilling area is 70 meters.
The minimum range required by drilling fluid equipment is 30 multiplied by 10 square meters, the minimum range required by drilling corollary equipment is 30 multiplied by 15 square meters, the width of a loop well site road of the drilling well site is 3 meters, and as the sum of the 30 meters plus the 30 meters is 60 meters smaller than the width of the drilling area by 70 meters, the length of the drilling well site can be the sum of the length of the drilling area by 98 meters, the width of the drilling corollary equipment by 15 meters and the width of the loop well site road by 3 meters, namely, the length of the drilling well site in the direction parallel to a straight line where the shoreline is located is 98 meters plus 15 meters plus 2 multiplied by 3 meters plus 119 meters; the width of the drilling well site is the sum of the width of the drilling area of 70 meters and the width of the loop well site road of 3 meters, namely the length of the drilling well site in the direction vertical to the straight line of the shore line is 70 meters +2 multiplied by 3 meters, namely 76 meters. The position coordinates of four corners of the drilling well site are determined to be (20558089, 4268159), (20558164, 4268146), (20558143, 4268019), (20558068, 4268032), respectively.
In the embodiment of the invention, in order to realize exploitation of a plurality of oil and gas wells with target points located in a target environment sensitive area, drilling well sites of the plurality of oil and gas wells can be arranged at certain positions away from a shore line of the target environment sensitive area. When the well site position, the well placement direction and the well site size of the well drilling well site are determined, in order to reduce the drilling investment cost of the multiple oil and gas wells, the position coordinates of the center of gravity of the target point of the multiple oil and gas wells and the straight line where the shore line is located can be determined, then the straight line where the well placement of the well drilling well site is located is determined on the basis of the minimum safety distance between the shore line and the well drilling well site and well site parameters of the well drilling well site in the direction of the straight line where the center of gravity of the target point is located and perpendicular to the shore line, and potential safety hazards caused by a target environment sensitive area to the well drilling well site are avoided.
