METHOD AND SYSTEM FOR EXACT DIRECTION OF DRILLING OF DOUBLE WELLS

摘要

FIELD: oil-and-gas production.;SUBSTANCE: for direction of path of drilling of the second well nearby the first well it is implemented feeding of changed in time electrical current to conducting casing or tail of the first well. It is additionally drilled the third well nearby peripheral section of the first well and it is formed conducting path lengthwise the third well between peripheral section of the first well and current generator. Then it is defined electromagnetic field of the second well, generated by current in the first well. Direction of drilling path of the second well is defined using definite electromagnetic field.;EFFECT: providing of alignment of the second well relative to the first.;8 cl, 4 dwg
