Abstract

Abstract: 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.

Key words: mobile electric igniter, detachable roller skid, open injection head skid, simultaneous ignition, fire flooding
