A Method of Borehole Trajectory Control Based on 3D GIS Technology

Abstract

The invention discloses a well track control method based on a three-dimensional geographic information system (GIS) technology, and belongs to the technical field of oil-gas exploration development. By adoption the GIS technology and a three-dimensional visual technology, three-dimensional visual spatial models including a three-dimensional visual scene spatial model covering a drilling target area, a three-dimensional model of a well traction of a deployment well and three-dimensional models of the well tracks a finished well, the deployment well and a drilling well are constructed. The well track of the deployment well and the well tracks of the finished well and the drilling well are visually represented according to the three-dimensional visual spatial models, the drilling design of the deployment well or the drilling parameters of the drilling well is adjusted, the well track of the drilling well is controlled, the phenomenon that the well track of the drilling well and the well track of the finished well interest is effectively avoided, it is guaranteed that the drilling well hits a target point according to the well track of drill design, and the well body quality is guaranteed.

Description

technical field [0001] The invention relates to a wellbore trajectory control method based on three-dimensional GIS technology, belonging to the technical field of oil and gas exploration and development. Background technique [0002] GIS technology, that is, geographic information system, (Geographic Information System or Geo-Information system, referred to as GIS). It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space with the support of computer software and hardware systems. [0003] The wellbore trajectory is the pre-designed shape of the wellbore axis before a well is drilled. The borehole trajectory is the shape of the borehole axis after a well is actually drilled. In the process of drilling design and actual drilling, there is a possibility that the wellbore being drilled and the completed wellbor...

Problems solved by technology

[0008] The purpose of the present invention is to provide a wellbore trajectory control method based on three-dimensional GIS technology, which overcomes the low accuracy of identifying wellbores intersecting each other in the prior art, which causes the wellbore being drilled and the wellbore that has been completed to intersect each other and be scrapped at the same time Defects
