对于低渗透致密砂岩储层的水平井，目前仍没有一种合理有效的测井解释方法能准确地评价此类储层的含油气性。以直接录取井筒内上返出的实物样品为基础的录井技术，能够直观有效地收集到地层含油气信息并进行评价，相对来说其评价结果更有一定的说服力。在对红河油田多口水平井的资料对比研究中，测井解释、综合录井评价及试采油数据并没有显示出比较一致的正相关性，甚至在一部分井中出现了很大的差异。针对此类差异，将研究区域内多口水平井的综合录井、测井资料进行了详细对比分析，从各自测量参数特征及原理方面展开论述，总结了形成解释差异的主要影响因素，并提出了通过测录双方测量参数的优势互补，建立起一套综合评价方法，让定量、定性参数的各自作用得以最大化发挥。为准确评价此类储层的含油气性提供了有效的思路。

Recently,for horizontal wells in tight sandstone reservoir with low permeability,there is still no reasonable and effective log interpretation method for accurate evaluation of hydrocarbon potential of such reservoir.Through directly admitting the physical sample back to the wellbore,the mud logging technique can visually and effectively collect and evaluate the hydrocarbon-bearing information.The results of the evaluation is relatively more convincing.In comparative study for multi-horizontal wells of Honghe Oil Field,the data of well logging interpretation,comprehensive mud logging evaluation and production test did not show much consistent positive correlation,and even have great difference in a portion of wells.In view of such differences,the author compared and analyzed data in detail between the mud logging and e-logging of many horizontal wells in the study area,discussed among the feature and principle of each measurement parameter,summarized the main controlling factors which caused explanation differences,put forward the complementary advantages of both parties through the measured parameters,finally establish a set of comprehensive evaluation method,which maximize the role of all the quantitative and qualitative parameters.Thus it provides an effective way for accurately evaluating the hydrocarbon potential of such reservoir.
