Abstract
Horizontal wells development technology has become an important means to improve the production of a single well. In this paper, according to the reservoir characteristics of tight oil of Yanchang Formation, some optimizations of horizontal well technology were made and applied in some wells. Through evaluating the exploitation effect concluding yield evaluation, regression and water content evaluation and single well evaluation of these wells, it can be seen that the single well production is enhanced greatly.
