Oil Casing Introduction

Hua Tong. Xiao-Hong Tang

Abstract: Oil casing is the pipe wall, used to support the oil and gas, to ensure normal operation of the post-completion wells at the drilling process. Each well, depending on the depth of drilling and geological conditions, should use several layers of casing. After set down casing will be cementing. Different form tubing and drilling pipe, it cannot be reused, a one-time consumable materials. Therefore, the consumption accounts of casing are over 70 % of all oil well pipes. Casing, according to usage, can be divided into catheter, surface casing, intermediate casing and production casing. This article provides a briefing including definition on the casing pipe, preparation, use, types, technical specifications, precautions when used.

Keywords: oil casing, definition, preparation, structure and specifications
