A Study On The Optimization Of Horizontal Well Steam Stimulation Parameters For Super Heavy Oil

Liaohe oil bearing area features abundant super heavy oil resource with OOIP exceeding 180MM tons. The current method of production is mainly vertical well steam huff and puff with limited single well control of the oil which results in low recovery factor and much residue resources.In this context, horizontal well steam stimulation comes in to play, and is phasing in the scene. Optimizing of the parameters for horizontal well steam stimulation is very much important for the efficient development of the super heavy oil resources.Based on the correspondence of parameters and effects of horizontal steam stimulation, the paper used digital simulation and orthoganalized experimental optimization designing method, in conjunction with the field production data, optimized the injection/production parameters for Du 84 block Xing One horizontal wells and Xing Four infill horizontal wells to ensure high efficiency of super heavy oil development for the Special Oil Company.
