Lakes Blue Energy NL(ASX:LKO)今日宣布,其Wombat-5气井的生产测试工作已暂时暂停,公司正推进延长压力恢复阶段,并为后续射孔增产程序做准备,以优化气井产能。 自今年2月9日上次公告以来,公司通过氮气举升工艺卸载钻井液,并对Wombat-5井进行了气体流入压力恢复诊断测试。该井在1500米水平段内发现三个强气流区,展现出良好储层潜力。然而,公司判断需额外操作才能实现全流量产气,因此暂停当前流动和清理作业,完成承包商设备撤离。
目前,经监管批准的压力测试延长阶段已同步启动,预计将持续收集长期压力数据,帮助评估储层特性。这一步骤将为后续增产措施提供关键依据。根据计划,压力测试完成后,公司将申请监管许可,重返井场实施射孔程序--即在水平储层段完成射孔,以提升气体流入井筒的效率。射孔是此类气井常用的增产技术,可打破近井地带污染,增加渗透率。 除射孔外,公司还考虑结合其他增强活动,如酸洗,进一步改善井的流动性能。
相关技术设计工作已启动,并与监管部门就所需审批展开沟通。尽管还需额外修复工作,但迄今为止的测试已提供了宝贵的储层和井筒性能信息。公司仍视Wombat油田为具有商业天然气开采潜力的区域,并将随着更多结果出炉及时向市场更新进展。
