Horizontal wells were adopted in the second development test of Liaohe Oilfield to fully exploit the potential of remain-ing oil fields. In order to improve the productive capacity, steam injection was carried out in some wells. The steam injection processes which were suitable for horizontal wells in Liaohe Oilfield were determined by optimizing the mature steam stimulation process. It included string optimization, dual string injection, multi-point steam injection and viscosity reduction cleanup which can ensure the safe, efficient implementation of the process. Efficient production after steam injection was achieved by all these measures.
