摘要
为提高梁8块低渗透储层的开发效果,在该区块沙四段部署了水平井梁8-平1井,对梁8-平1井进行井身轨迹和完井结构优化,应用了连续油管喷砂射孔及环空分段压裂工艺,提高了油藏的泄油面积.实施情况和应用效果表明,该井采用连续油管喷砂射孔、环空分段压裂工艺投产后,产能达到周围油井的5倍,井组控制储量得到有效开发,效果良好.连续油管喷砂射孔、分段压裂工艺实用性强,具有较好的应用前景.
To improve the development effectiveness ployed in S-4 member in the block. The optimization of Liang-8 block, a horizontal well （ Liang-8-P1 ） was deof wellbore trajectory and well completion structure was conducted for Well Liang-8-P1, the technology of abrasive perforating in coiled-tubing and staged fracturing in annulus was applied, and the drainage area of reservoir increased. Implementation situation and application effectiveness show that after putting the well into production with the technology, the productivity is five times of other wells, the reserves controlled by the well group are effectively developed, and effectiveness is better. The technology has a strong practicability and a better application prospect.
