摘要
水平井开发已成为油田实现稳定发展的主导技术,然而水平井水平段动用不均严重制约了水平井产能的发挥。通过水平井井温测试资料深入分析水平井水平段的动用状况,从而指导水平井双管注汽、多点注汽、优化配汽器位置等措施实施,提高水平井储量动用程度,发挥了水平井的优势。该技术已累计规模应用1200余井次,指导工艺措施实施增油效果显著。
The number of horizontal wells is constantly increasing with the development of Liaohe Oilfield,and it has become the dominant technology to realize stable development of the oilfield.But the producing unevenness of the horizontal section of horizontal wells has critically constrained the capacity play of the horizontal wells.In this paper the horizontal section producing extent in horizontal wells was analyzed deeply based on the temperature testing data,thus direct the technological measures such as two-pipe steam injection technology,multi-point steam injection technology,and optimize the steam distributor locations so as to increase the producing extent in the horizontal wells and bring into play Horizontal well advantage.The technique has been applied for 1200 well/times in large scale in Liaohe Oilfield and the testing data have been used in directing technological measures with substantial oil incremental results.
