METHOD AND SYSTEM FOR DRILLED WELL DEVELOPMENT AND MEASUREMENT Russian patent published in 2015 - IPC E21B47/02 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to facilities intended to control orientation of well drilling. The suggested method for drilled well development and measurement contains the following stages: drilled well is developed by drilling with a drilling tool, at least one measuring line is strained between hinged fastening point at the carrier for drilling tool over the ground surface and measuring body in the well. At that drilling tool and measuring body are hold by the carrier. Further the measuring body is introduced along the well axis and run in to the well in the ground. At that the measuring body comprises a body with diameter corresponding to diameter of the well, and the above body is in contact with wall of the drilled well. Further by measurement of angle and distances by measuring instrument positions of at least two vertically detached points of the strained measuring line, against two identified positions of the line points, by means of data processing device position of the measuring body is identified as measure of the drilled well position. There is also claimed system for implementation of the said method.

EFFECT: provided accuracy for identification of the measuring body position and its spatial orientation in the well.
