涠西南凹陷复杂储层测试资料分析与探索

针对涠西南凹陷复杂储层试井解释问题大概划分为储层问题;流体问题;测试问题三大类。探索性提出了一些试井解释方法(低渗透试井、早期试井、PPD诊断曲线、SLPD诊断曲线以及Y函数),并总结归纳了目前涠西南凹陷复杂储层的试井解释方法(主要是针对探井、评价井),同时结合区域资料展开了复杂储层产能评价工作,应用试井解释结果及节点分析方法对该工作的有效性进行了充分的论证。以X1井和X2井为例,介绍了一些探索性的试井解释方法和产能评价工作。

针对油田试油技术的研究与探讨

近阶段的油田试油试采公司,主要的是开发了定方位射孔和动态负压射孔技术,纷纷探究了深层试气工艺技术及试气评价方法,这些方法互相配合完善着地层测试技术。此外,经过试新研究了射孔、压裂、排液一体化的新高技术,以及低渗透储层水性判别及试井评价技术,这些工艺技术的相互支撑,满足了勘探深层试气、外围复杂储层资料录取、定向精细及多层压裂、低渗透储层试井评价的需求。上述多项技术填补了国内空白,达到了国际先进水平。

Test evaluation for vertical fracture wells in low permeability reservoir

As flow environment is poor in low permeability reservoirs, wells are always fractured in order to gain better economic benefits. Well testing analysis is very necessary for fracturing wells. However, available test analysis methods are of slow fitting speed and low fitting precision. In this paper, we first use a comprehensive evaluation method of analytical well testing, numerical well testing and well testing design. Many dynamic parameters such as fracture length, fracture conductivity, skin factor, etc are obtained. An example to illustrate accurate results of this method is given.
