河南油田老井复查寻找新储量研究及效果

老井复查工作中，充分利用地震资料控制构造，结合实钻资料分析构造；根据小层追踪对比，分析砂体展布；采用多种解释方法，结合平面油水关系评价油层。老井挖潜具有涉及面广、隐蔽性强、投资少，见效快等特点，是深化地质认识，增储上产的一种有效方法。近年来，通过老井复查，相继在南阳、泌阳凹陷发现了一些高产油井，提出了一些新的井位布署建议。因此进一步拓宽老井挖潜领域，不但对于老区寻找新储量十分重要，而且对于新区勘探开发也具有一定的借鉴作用。

A Study on Searching for New Reserves Through Old Producer Reviewing in Henan Oilfield

In old producer reviewing, structures are controlled through fully utilization of seismic data and are analyzed in conjunction with real drilling data; sandbody distribution is analyzed based on tracing and correlation of thin layers; and oil layers are evaluated by using multiple interpretation methods and combining with plane oil-water relation. Old producer reviewing has the characteristics of needing small investment and producing an instant effect. It is an effective way to enrich geologic knowledge and increase reserves and production. Several producers with high oil rate have been discovered in Nanyang and Biyang depressions through oil producer reviewing. Further widening the field of oil well production potential tapping not only be vital to searching for new reserves in an oil oil field, but also can be used for reference in exploration and development in new areas.
