在高压高温（HP/HT）井中进行射孔作业需要大量的工程准备工作，尤其是在多层完井中，射孔顺序至关重要。以往，在带压井条件下，连续油管一直是默认的输送方式，但多层HP/HT完井作业通常需要单次下钻，这可能导致高超压对枯竭层造成损害，同时增加成本、复杂性和地面作业面积。本文介绍了深井HP/HT完井中电缆射孔作业的工程设计和执行。
在高压/高温井中对长段井段进行射孔作业，需要一种能够平衡机械强度、压力控制、作业灵活性和海上作业限制的输送方式。这些限制包括有限的甲板空间、起重机能力以及容纳额外人员的空间。
在本案例中，经过对机械要求、操作风险和钻井场地限制的评估，选择钢丝绳作为最佳输送方式。
Perforating in high-pressure, high-temperature (HP/HT) wells requires extensive engineering preparation, particularly in multizone completions where perforation order is critical. Historically, coiled tubing has been the default conveyance under live-well conditions, but multizone HP/HT settings typically force a single-run interval that can expose depleted zones to damage as a result of high overbalance while adding cost, complexity, and surface footprint. This paper describes the engineering and execution of a wireline perforation program in a deep HP/HT completion.
Perforating long intervals in HP/HT wells under pressure requires a conveyance method that balances mechanical strength, pressure containment, operational flexibility, and offshore deployment limitations. These include limited deck space, crane capacity, and accommodation for additional personnel.
In the featured case, wireline was selected as the optimal conveyance method after evaluating mechanical requirements, operational risks, and rigsite limitations.
