| 摘 要： | 现有关于低阻层出油的研究中，未曾涉及油气藏开发过程中自身动态变化（油水界面下降）造成的低阻层出油现象。这里在常规测井资料多井研究的基础上，通过新老井的综合对比，老井开发历史以及产出流体性质分析，准确认识了一个具备高能气顶的油藏对不同构造部位井造成的影响，并藉此提出气顶能量作用下油水界面下降，形成低阻层出油的可能性。总结了该类油层的成因机理、特征以及解释评价的关键，对低阻油层成因类型和识别手段做出了补充，有效避免了勘探开发中油气层的漏失。 |

| Abstract： | There is no notice in present research about problems in low resistivity hydrocarbon reservoir that forms from the exploitation changing of hydrocarbon pools, which leads to a movement of interface between oil and water. Based on research of multi-wells with routine logging data, this paper interprets the influence in wells at different tectonics position caused by a high energy gas cap in the reservoir reasonably, proposes a possibility that low resistivity reservoir will outputs hydrocarbon because of the oil-water interface movement caused by high energy gas cap, with mass works in comprehensive comparison of new and old wells, and analysis of old wells exploitation history and fluid properties. It summarizes the genetic mechanism, feature and key of interpretation and evaluation, and makes supplements of low resistivity hydrocarbon reservoit gensis types and idenification methods, effectively avoid the missing of hydrocavbon reservior in exploration and development. |
