Oil and Gas Well Hole Structure and Application in Superdeep Well with Analysis of Material Properties

摘要

The designing level of oil and gas well hole structure and application in superdeep well with analysis of material properties play a key role in the expected production target to superdeep oil and gas wells. This paper introduces the hole structure of standard casing size series, main problems in superdeep wells with analysis of material properties, and solving means such as: using liner as production casing, cementing under small clearances of borehole-casing annulus and intermediate casing-production casing annulus, reaming and close clearance hole structure, analysis of material properties and so on. By application, the study above has a good practicality.
