Description

一种储能修井机 技术领域
本发明涉及修井机技术领域，具体涉及一种储能修井机。
背景技术
修井机是对油田井下管柱或井身进行维修的专业化机械设备，主要用于油管、抽油杆和抽油泵的提升与下放等作业。目前柴油机是修井机的主要动力来源，为修井机行走和作业提供动力。但柴油燃烧会产生大量有害气体，造成环境污染，既不符合国家节能减排政策，也不符合环境保护的要求。柴油发动机仅将柴油燃烧所产生热能的30％转化为机械能，导致柴油修井机效率较低。柴油机故障率高，功率利用率低，修井作业中柴油机约66％的时间处于空载运行状态。
修井过程中，起、下管柱为典型间歇性循环作业，提升管柱时发动机大功率输出，卸扣和摘吊卡等辅助作业时发动机处于低载或空载运行。传统修井机为满足最大钩载和钩速要求，需配置较大功率发动机，造成较大的功率浪费。最大功率需求主要体现在油管提升工况，而一个完整的提升过程，提升时间只占整个作业周期的1/4～1/3，其余时间负荷小，下降还需要克服大钩重力，系统为负功率。
修井机作业周期短，搬迁频繁，若以高压电网取电，需电力部门审批，受限于“高压电网作业审批时间长和接电危险”等因素，限制了电驱修井机的灵活性。若以抽油机变压器低压端取电，抽油机变压器功率小于绞车电机功率，无法满足大修井机作业所需的钩载和钩速等功率要求。大多数油井采 用变压器容量一般为50～80kVA。
基于上述各种问题的存在，亟待一种新的修井机。
