• 可在任何尺寸的基管上加工 • 越小基管，越厚胶筒 • 胶筒越厚，越大膨胀，越高压差 • 越长胶筒，越高承压能力 • 可以膨胀到不规则井眼或套管

Planning is essential in HPHT cementing 高温高压固井方案至关重要
• Lab testing 实验室试验 – Simulate job conditions as accurately as possible – Do not assume standard API conditions – Strict quality control of all blends (SSA-1 content) – Cementing rep. offshore/onshore in charge of bulk management – Quality control all materials and perform confirmation testing using field samples – Material traceability back to producer – Aim for a single chemical batch number, especially for retarders. – Communication is important to remain proactive – Allowance in design for change in plans • Contingency planning应急方案 – HPHT testing is time consuming, plans may change
