Abstract
Description
Technical Field
[0001] The present application relates to the technical field of well inclination measurement, and in particular to a low-side measurement device for well inclination measurement. Background Art
[0002] Well inclination refers to the angle between the wellbore trajectory and the vertical direction, and is usually used to describe the degree of inclination of the wellbore in the formation. In the fields of oil drilling and geological exploration, well inclination is a very important parameter, which can help engineers understand the direction of the wellbore and the characteristics of the formation, so as to formulate a more appropriate drilling plan.
[0003] Well inclination is usually measured using equipment such as magnetic inclinometers and gyro inclinometers. These devices can measure the inclination angle of the wellbore and the azimuth of the wellbore in the formation. By analyzing these data, the wellbore trajectory can be better controlled to avoid encountering formation obstacles and improve drilling efficiency.
[0004] When measuring with a magnetic inclinometer, the operator needs to hold the pipeline with one hand to drive the measuring head to move down inside the hole. At this time, the operator also needs to use the other hand to control the device display. When holding the pipeline, if the operator is distracted and does not hold the pipeline tightly, the measuring head will fall rapidly inside the hole, causing confusion in data detection.

[0031] A second "mouth"-shaped plate 8 is horizontally welded on the inner side of the two groups of rotating shafts 7, and the second "mouth"-shaped plate 8 is convenient for stably fixing the internal structure; and horizontal rectangular holes are arranged on both sides of the second "mouth"-shaped plate 8, so as to facilitate the displacement of the internal structure inside the holes; and a fixed frame 9 is welded on the outer side of the horizontal rectangular hole of the second "mouth"-shaped plate 8, and the fixed frame 9 is convenient for providing stable movement for the internal structure.
[0032] Fixed frames 9 are horizontally arranged on both sides above the measuring head 1, and a guide rod 10 is connected to the inside of the fixed frame 9 in a horizontal sliding manner. The guide rod 10 can provide stability for the structure on one side during displacement; a "U"-shaped fixed plate 11 is welded on one side of the guide rod 10, and the "U"-shaped fixed plate 11 can stabilize the inner structure for rotation; a rotating roller 12 is rotatably connected to the inside of the "U"-shaped fixed plate 11, and the rotating roller 12 can be displaced by rotation without affecting the inner structure; a spring 13 is arranged on the outside of the guide rod 10, and the spring 13 is convenient for providing horizontal extrusion work; and the spring 13 is welded on one side of the "U"-shaped fixed plate 11 to improve the stability during extrusion; a baffle plate No. 14 is vertically welded on both sides of the "U"-shaped fixed plate 11, and the baffle plate No. 14 is convenient for subsequent positioning; a baffle plate No. 2 15 is vertically welded around the inner side of the No. 2 "mouth"-shaped plate 8, and the baffle plate No. 2 15 can play an effective limiting and fixing role.
[0033] The implementation principle of a low-side measurement device for well inclination measurement in the present application is:
[0034] First, place a No. 1 "mouth" shaped plate 4 outside the hole reserved on the ground, then thread the measuring head 1 and the pipeline 2, then pass the measuring head 1 through the inner side of the two sets of rotating rollers 12, and then insert the measuring head 1 into the hole.
[0035] Secondly, when the displacement of the pipeline 2 drives the measuring head 1 to fall inside the hole, it can be conveniently detected by the measuring head 1. The measuring head 1 uses the direction of the magnetic field lines of the earth's magnetic field to measure the well inclination angle and the well inclination azimuth. Among them, the S pole of the compass always points to the north. When measuring the well inclination angle, the cross pendulum always points to the direction of the gravity line. The angle between the gravity line and the instrument axis is the well inclination angle, which is read by the position of the pendulum on the well inclination scale plate. When measuring the well inclination azimuth, the plumb line where the pendulum is located and the instrument axis constitute the well inclination plumb plane, and the intersection of the well inclination plumb plane and the horizontal plane is the well inclination azimuth line. The angle between the radial line where the projection position of the pendulum on the compass surface is located and the N pole of the compass is the well inclination azimuth. Through the sleeve 6 inside the positioning plate 5, it can be rotated inside the sleeve 6 through the rotating shaft 7, which is convenient for the pipeline 2 to change the angle in the two sets of rotating rollers 12 inside the second "mouth" shaped plate 8, and improve the smoothness of the pipeline 2 during displacement.
[0036] Finally, when the pipeline 2 needs to be fixed, the "U"-shaped fixing plate 11 on the outside of the rotating roller 12 is squeezed by the spring 13 through the protrusion 3 on the outside of the pipeline 2, so that the two groups of rotating rollers 12 fit under the protrusion 3, thereby preventing the pipeline 2 from moving, and the No. 1 baffle 14 on the outside of the "U"-shaped fixing plate 11 is limited by the No. 2 baffle 15 on the inside of the No. 2 "mouth"-shaped plate 8, preventing the rotating roller 12 from excessively squeezing the pipeline 2 and causing damage to the pipeline 2.
[0037] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
