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。
Methods Based on the problems of low utilization, low utilization of reserves and low development efficiency in the development wells of Ah Beian Andesite reservoir, a number of comprehensive studies were carried out on influencing factors of single well productivity and the formulation of dividing criteria for favorable oil zones. Aim To find out the rebuilding measures and application principles of the oil reservoir in the Bei’an Andesite. Results According to the selected principles, the oil layer was rebuilt in the Arian andesite reservoir, which improved the utilization degree of the oil field and increased the well A 2 to the oil-bearing favorable area and realized the high production contiguity of the main oil-bearing block, making the first three Twice as many times as the development program targets. Conclusion The selection and implementation of rational acidizing and fracturing reformation measures are not only favorable measures for improving the exploitation efficiency of the reservoir, but also provide successful examples for the stimulation and improvement of andesite reservoirs.
