Problems solved by technology

However, due to the complexity of the drilling process, it is very difficult to correlate offset well data, so the existing technology cannot achieve the purpose of assisting underground wellbore planning and drilling operations through offset well data analysis

Embodiment 1

[0040] 1. A brief introduction to the drilling process in the formation and the drilling equipment used in the drilling process is as follows:

[0041] refer to figure 1, the drilling process may use a system of platforms and a derrick 210 positioned on a wellbore 212 that may be formed by rotary drilling. A drill string 214 terminating therein with a drive drill pipe 220 may be suspended within the borehole or attached to a rotary table 218 for rotating the drill bit 216 . The drill string 214 is typically hung from a hook 222 to which a moving block is attached, to which the drive drill rod 220 may be connected by a rotation 224 which allows the drill string 214 to be rotated relative to the hook 222 . Drill string 214 and drill bit 216 may also be rotated from the surface by a "top drive" type drill. The drill string 214 may also be assembled together from tubular sections ("joints" or "brackets") that are connected together.

Embodiment 2

[0057] A method for generating a visual representation of wellbore drilling parameters described in Embodiment 1 can be applied to the following situations:

[0058] 1. Applied to observe time fracture data, drilling operation parameters, and environmental parameters

[0059] A visual representation method for generating wellbore drilling parameters is applied to draw a two-dimensional shape diagram of a predetermined wellbore length (a rectangle corresponding to a wellbore section) at an appropriate position on the time-depth curve of the well, such as Figure 5 shown. therefore, Figure 4 The x-axis of B can be converted to a plot of time in days and the axial length of the wellbore to show the progression of the time-depth curve, see Figure 4 The length of each rectangle explained by B, is multiplied by a factor to preserve relative time, rather than to make changes in each bracket visible to the analyst. Viewing time-fracture data in this way allows analysts to quickly...

Abstract

The invention provides a method for generating a visual representation of wellbore drilling parameters. The method comprises the following steps of segmenting a drilling process, drawing a two-dimensional shape, drawing a segmented two-dimensional shape graph of the drilling process on a computer, and outputting a visual map. The method for generating the visual representation of the wellbore drilling parameters in the invention has the beneficial effects that the correlation between offset well data is established by improving the visual analysis technology of the drilling performance data; the purposes of assisting the planning of the underground wellbore and the drilling operation is realized; the visual analysis of various drilling parameters is realized; the drilling operation is facilitated; and the visual analysis of the drilling operation data is achieved.

Description

technical field [0001] The invention belongs to the technical field of borehole drilling research on underground rock formations, and relates to a method for determining formation drilling response and drilling operation parameters, and in particular to a method for generating a visual representation of wellbore drilling parameters. Background technique [0002] Drilling operation is the project of using mechanical equipment to drill the formation into cylindrical holes with a certain depth. In geological work, the use of drilling equipment to drill underground cylindrical holes with a small diameter and a large depth is called drilling. The diameter and depth of the well depends on the purpose of the well and the burial depth of the minerals. Drilling wells for oil, natural gas, and groundwater are larger in diameter. The main functions are: ① Obtaining underground physical data, that is, taking cores, ore cores, cuttings, liquid samples, gas samples, etc. from drilling. ...
