摘要
苏里格气田特有的低渗、低压、低丰度、低产等地质储层特性,使得压裂改造成为区块建产开发的必要手段。实践证明,水平井压裂工艺技术的研究与应用为实现低成本开发、提高单井产量、保证持续稳产的更高目标提供了更好的技术支持。截至目前,苏75区块已经开发生产水平井6口,均采用裸眼封隔器多级分段压裂技术进行开发应用,都取得了显著的效果,其开发投产气产量是普通直井的3～6倍,表明水平井裸眼封隔器多级压裂技术已应用成熟,为今后的水平井开发应用提供了技术支撑。
The gas reservoir of Sulige Gas Field has the features of low permeability,low pressure,low abundance and low productivity,in order to develop the block,fracturing is a very important means.Practice showed that the fracturing technology of horizontal well was the key way to reduce the development cost,improve single well production and ensure stable production.Until to now,six horizontal wells were developed by using open hole packer multistage fracturing technology in Su 75 block,the yield was 3~6 times compared to the general straight well.The application results of the technology provided technical support for development of horizontal wells.
