概观:

The use of new technologies and developments in the field of autonomous geophysical equipment allowed us to move to a new level of quality of work on the study of oil and gas fields in directional and horizontal wells during development and control of development.

Existing directional wells are investigated on wireline hoists with a wire that allows working under pressure up to 25 MPa without stopping and bleeding the well, which affects the quality of the material obtained during the study and reduces the labor costs for delivering equipment necessary for disposal of products received from the well boring .

Horizontal wells are studied in installations with a flexible tubing autonomous (CT) devices mounted on the tip of the pipe, allowing flushing the well during the well test.

The quality of the material recorded by autonomous instruments on CT is no different from the material obtained by recording on a hard cable, but for this, the A-50 installation is not required, and the length of the studied horizontal section is an order of magnitude greater.

Types of research autonomous devices:

  • general and interval debit and pick-up;
  • technical condition of production casing and tubing;
  • tightness of the packer;
  • the presence of annular circulation;
  • the percentage of water in the reservoir;
  • depth of installation of elements, well design and depth of the bottom.
