| 摘要: |
| 胡尖山油田元72区延9段油藏属于低孔中渗岩性-构造油藏。研究区块处于开发后期,部分井出现含水上升快,域底水含水高等现象。通过常规测井响应识别油水特征,同时选取典型样品的测井参数,运用交会法、P1/2正态概率法和视地层水电阻率法等对油层组进行综合识别。然后,根据单井油水综合识别成果对各井的油水层进行纵、横向的连井分析,通过对各个方向油水连井剖面以及油水在平面上展布特征的分析,得出研究区目地层的油水特征及分布规律,为胡尖山油田元72区延9油藏的下一步开发方案的调整和优化提供基础。 |

| Abstract: |
| The Yan-9 oil reservoirs in the Yuan-72 block, Hujianshan Oil Field, northern Shaanxi are interpretated as the low-porosity and medium-permeability lithologic-structural oil pools. The oil-water recognition is based on the well logs, including intersection method, P1/2 normal probability method, and apparent formation water resistivity method. The integration of well-tie sections and planar distribution of oil and water is conducted to examine the oilwater characteristics and distribution, and will provide new information for the further development of the Yan-9 oil reservoirs, Yuan-72 block, Hujianshan Oil Field. |
