濮城油田侧钻井方案研究及效果评价

Side-well study Side-well study and Effect evaluation in PuCheng oil-field

濮城油田正式投入开发已 2 0余年 ,由于油田投产时间长 ,井况损坏严重 ,现存在大量的事故井、报废井、低效井 ,油田开发形势严峻 ,整体效益明显下滑。 1 999- 2 0 0 0年濮城油田以提高油田开发效益为宗旨 ,开展构造精细解释、油藏描述 ,运用数摸技术 ,深入研究油田剩余油分布规律。在经济评价的基础上 ,对长期关停的部份事故井、报废井、低效井优选侧钻方案。方案实施后 ,增加了可采储量 ,改善了油田开发效果 。

PuCheng oil-field has been exploited for more than 20years. Due to developing for so long,the condition of well is so bad. There are a large number of accident wells, rejection wells and low effectient wells,resulsting in total benefit going down evidently. in order to improve developing level of the oil field, those have been done well, construction analysed accurately, reservior described and remaining oil distribute law studied in a deep-going way by mathematic modeling method. On the base of economic evaluation, the preferably side-wells' pro jects were chosenas parts of accident wells, rejection wells and low effectient wells. After the projets put in practice, recoverable reserves was increased, developing effect of oil filed was improved and experience for reference was given for comprehensive adjustment of oil field.
