METHOD FOR WELL DEPTH MEASUREMENT DURING WELL SURVEY

摘要

FIELD: survey of boreholes or wells, particularly measuring depth or liquid level for obtained survey data binding to geologic profile. ^ SUBSTANCE: method for well depth determination with the use of marks installed along casing pipe length and by reading above marks involves moving marking unit of marking plant arranged in the well along with investigating geologic profile and determining structural casing pipe members; binding geologic profile and structural casing pipe members to depth, wherein geologic profile binding is carried out from data obtained by natural rock radioactivity module and structural casing pipe members binding is performed with the use of clutch locator module, which are connected to logging cable and are lowered in well along with marking plant. ^ EFFECT: increased accuracy of well depth, geologic profile and structural casing pipe member boundaries determination from well survey. ^ 1 dwg
