作为一种全新的水平井完井工具,遇水/遇油的自膨胀封隔器主要是对常规封隔器进行创新,使自膨胀封隔器完全取代传统封隔器来完成水平井完井的操作。自膨胀封隔器的使用可以使水平井完井的效率得到提高,降低水平井完井的风险,并在费用上得到客观的减少。本文主要从自膨胀封隔器于多分支井完井、固井辅助密封和水平井的裸眼分段这三个方面的应用对其进行相关介绍,并表现出其完井技术的优势与工艺特点。经过我国相关的技术人员对其进行的多次试验证明,遇油/遇水的自膨胀封隔器对水平井完井的技术运用是有效的,且对我国极为复杂的油气藏的充分开采具有深刻的意义。
As a new horizontal well completion tool, the water / oil-bearing self-expanding packer is mainly to innovate the conventional packer so that the self-expanding packer completely replace the traditional packer to complete horizontal well completion The operation. The use of self-expanding packer can improve the efficiency of completion of horizontal wells, reduce the risk of completion of horizontal wells, and objectively reduce the cost. This paper mainly introduces the application of self-expanding packer in the multi-branch well completion, cementing auxiliary seal and horizontal section of the naked eye, and shows the advantages and technical characteristics of the completion technology . After several tests carried out by our country’s related technical personnel, it is proved that the self-expanding packer meeting the oil / water encounter is effective for the technical application of horizontal well completion and has the following advantages for the extremely complicated oil and gas reservoir in our country: Profound meaning
