Horizontal Well Deployment Optimization in Badaowan Formation in Wellblock Hongqian-1

Abstract

Abstract: In view of the geological characteristics of the delineation and undeveloped reserves in Badaowan heavy oil reservoir in Wellblock Hongqian-1 in Junggar basin, research on the integral steam-stimulation horizontal well deployment optimization is made by means of numerical simulation and economic analysis. According to the economic production limits under different oil prices, the technical parameters have been optimized for horizontal well deployment. It is determined that the low limit of pay zone thickness for horizontal well development is 2 m, the lateral length is 200 ～300 m, the well spacing is 100 m. The study shows that using integral steam-stimulation horizontal well development in this well block can get satisfactory results, and the recovery factor can be up to 28.4%.

Key words: Junggar basin, heavy oil reservoir, horizontal well, development, optimization
