阿北安山岩油藏油层改造及增产措施

Formation improvement and stimulation measures for Anshan lithologic reservoir, Abei.

方法 根据阿北安山岩油藏开发井利用程度低、储量动用程度低、开发效率低等问题 ,开展单井产能影响因素及含油有利区带划分标准的拟订等多项综合性研究。目的 找出阿北安山岩油藏油层改造措施及应用原则。结果 按所选原则对阿北安山岩油藏进行油层改造后 ,提高了油田的动用程度 ,使阿 2井区上升为含油有利区 ,实现了主力含油区块高产连片 ,使该油田开发前三年以开发方案指标的二倍运行。结论 合理的酸化、压裂改造措施的选择及实施 ,不仅是本油藏提高开发效率的有利措施 ,同时也为安山岩油藏的增产改造提供了成功的范例。

Method For Anshan lithologic reservoir, aiming at problems, such as low efficiency of developing wells, low development degrees of reserve, etc, comprehensive study on factors affecting single well productivity and standards preparation for delineating of oilbearing zones are performed. Purpose To find out improvement measures and application principles for Anshan lithologic reservoir in Abei area. Result After improving mentioned reservoir with the selected principle, development degree of this oil field is heightened and made A 2 well area a favorable oilbearing area and joined together with main producing area. Finally, development result for the first three years is two times that of projected indexes. Conclusion Selecting and implementing reasonable acidizing treatment, fracturing improvement measures are suitable for improving development results, and they also provided successful example for stimulating Anshan lithologic reservoir in the future. \;
