Things To Note When Purchasing Tubing And Casing

Oil pipes are widely used to transport crude oil and natural gas to the surface after drilling, and they are also under the pressure of exploration.Oil casing is widely used to fasten the well wall or well wall of oil and gas wells, and is an important guarantee for normal operations after drilling and completion of oil and gas wells. So, what should you pay attention to when choosing tubing and casing? Read on to learn more about this.

Based on the exploration and development deployment and drilling plan, users need to develop a demand plan in advance, including model, steel grade, buckle type, wall thickness, length range, weight, quantity and special requirements, such as specifications and grades, thread grease type, and thread protection type. Here are some things to consider when buying tubing and casing.

(1) Clarify the pipe model, steel grade, thread type, wall thickness, length range, weight, quantity and special requirements.

(2) Clarify casing standards, such as API standards, national standards, industry standards, enterprise standards, etc. Relatively speaking, API standards are relatively loose, and each standard is slightly different. When filling in order conditions, the standards must be clear. Typically API pipelines are used.

(3) Check the supplier’s sales of similar products in the past three years. Is there a record of poor performance, quality and service conditions?

(4) Clarify pipeline quality inspection methods, implementation standards, inspection items, judgment standards and other matters.

(5) It is recommended that technical personnel from user units, testing institutions, purchasing departments and related departments participate. Drilling operation technicians can be invited to participate when necessary. With full consideration of quality, choose manufacturers with reasonable prices.

(6) Procurement in strict accordance with prescribed procedures and requirements.
