摘要

辽河油田水平井的应用已由试验阶段进入到规模应用阶段。依照数值模拟及理论研究,在油层特性参数相近的情况下,水平井生产效果与水平井段长度呈现较好的线性关系,但实际生产中水平井长度的优势发挥不明显、水平段动用不均等问题日益突出。注汽强度不合理、水平段吸汽不均、井间干扰等是影响水平井生产效果的主要因素。文中在采用油藏数值模拟、油藏工程计算等研究手段并结合现场实际的基础上,提出了增大注汽强度、均匀注汽、组合式吞吐等技术手段,提高了水平井动用程度,且现场应用效果显著。

Abstract

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.
