摘要:
某风险区块主要勘探目的层为基底花岗岩–变质岩裂缝性油气藏，介绍了现场录井施工队伍在缺少足够参考资料的情况下，针对该类油气资源的发现、判断及流体特点识别等问题采取了一系列的方法与措施，提出了现场使用岩石薄片、地层压力预测等技术与传统录井方法相结合，实现了油气异常显示的准确发现与判断；利用3H法、C2/C3法、烃比值法综合应用识别地层流体性质，并通过实例验证了该措施的有效性。
The exploration target layer of a risk exploration block was a fractured oil and gas reservoir in basal granite-metamorphic rock. A series of methods and measures were adopted to discover and identify the oil and gas reservoir and characteristics of fluids in the absence of sufficient references. The combination of traditional logging methods with rock thin slices and formation pressure prediction is proposed to identify anomaly oil and gas show accurately; and 3H method, C2/C3 method, hydrocarbon ratio method are used to tell the formation fluid property, and these methods are proved effective by examples.
