移动式火驱电点火器配套起下装备的研制

Development of the Equipment Supporting Mobile Electric Igniter Trip in Fire Flooding

火驱是稠油油藏有效的开发方式之一,油层点火是火驱成功的前提。针对传统连续管车在移动式火驱电点火作业中存在占井周期长、运行成本高等问题,研制了橇装移动式电点火器配套起下装备。该装备主要由可拆卸滚筒橇、打开式注入头橇组成,可在连续管不被截断的情况下,将作业橇组移动至其他井组进行电点火器的起下作业。现场应用效果表明:该装备可满足多口井同步点火需求,具有利用率高、适用性强的特点,单井点火运行成本降低60%以上。该技术可为火驱的大规模实施提供技术支持。

Fire flooding is one of the most effective development methods for heavy oil fields,and oil layer ignition is a prerequisite for successful fire flooding.The mobile electric ignition operation of traditional coiled tube vehicles has problems such as long well occupation period and high operating cost during fire flooding.In response to these problems,skid-mounted equipment was developed to support electric igniter trip.The equipment is mainly composed of a detachable roller skid and an open injection head skid,which can move the work skid group to other well groups for the operation of electric igniter trip without cut off the coiled tube.The field application results show that the equipment can meet the simultaneous ignition requirements of multiple wells,with high utilization rate and strong applicability,and the operation cost for single well ignition is reduced by more than 60%.This technology can provide a technical support for the large-scale implementation of fire flooding.
