录井资料在兴隆台潜山开发中的应用

The Application of Logging Data in the Development of Buried Hill in Xinglongtai Area

摘要: 兴隆台潜山是辽河油田公司产能建设的重点区块，该块为裂缝型块状底水变质岩潜山油藏。构造复杂、岩性多样、储层非均质性强、含油幅度超过2300 m。实施过程中，针对潜山顶面难以准确判别的问题，综合应用岩屑、旋转井壁取心、元素录井资料，及时卡准太古界潜山顶面；针对裂缝性储层油水解释难的问题，通过建立皮克斯勒图版、湿度比值图版识别油水层，同时结合定量荧光、测井等资料进行综合解释，指导试油井段优选，确保新井实施效果。该做法为辽河油田古潜山油藏快速卡层中完、定层射孔提供了有力的技术支持。

Abstract: Xinglongtai Buried Hill was the important block for productivity construction in Liaohe Oilfield, it was a fractured massive metamorphic buried hill reservoir with bottom water. It had complicated structure with varieties of lithologic properties and strong reservoir heterogeneity, and the oil-bearing amplitude was more than 2300 m. Due to the difficulty of judging Xinglongtai buried hill’s surface in the process of development, debris, rotary sidewall coring and element logging data were used to confirm it in time. In allusion to the problem of oil and water interpretation in fractured reservoirs, a Pixler gas ratio chart and a humidity ratio chart were established to solve the problem. At the same time, combined with quantitative fluorescence and logging data, a comprehensive interpretation was carried out for guiding the selection of oil test intervals and ensuring the efficiency of new oil well. This method provides a strong technical support to quick determining the target zones and perforation in given layers.
