The application of horizontal wells in Liaohe Oilfield has moved frompilot phase into large-scale application stage. According to numerical simulation and theoretical studies,under the similar reservoir parameters, it shows good linear relationship between the producing effect of horizontal wells and production horizontal well length. However, the advantage of horizontal well length is not obvious in the actual production, and the use of horizontal inequality becomes increasingly prominent. Unreasonable steam injection intensity, uneven horizontal steam absorption and well interference are the main influencing factors for the horizontal well producing effect. Based on the numerical reservoir simulation and reservoir engineering calculation, combined with field practice, the techniques such as increasing steam injection intensity, even steam injection and modular handling are proposed, the uses of which enhance the producing degree of horizontal wells. The field application results are obvious.
