塔河油田碳酸盐岩油藏水平井部署方法

塔河油田超深层碳酸盐岩油藏的主要储层为碳酸盐岩缝洞系统，存在着很强的非均质性，油田水平井开发难度较大。通过研究和实践，提出了应用三维地震资料解释结合岩溶、断裂及构造、古地貌、地震属性参数等综合分析、评价部署水平开发井的技术方法。其中，振幅变化率、相干体、波阻抗反演等地球物理预测参数技术发挥了特别重要的作用，提高了水平井的成功率，为超深层碳酸盐岩油藏水平井开发部署提供了技术支持。

Methods of disposing horizontal wells in carbonate reservoir in Tahe Oilfield

The deep reservoir beds in Tahe oilfield are mainly fractured carbonate reservoirs, which have strong inhomogeneity. Horizontal wells are difficult to be disposed. A suite of methods for disposing horizontal wells has been developed based on 3-D seismic data. The author proposed to evaluate the disposition of horizontal wells by combining the information from analyses of karsts, faults, structures, palaeogeomorphology, and seismic parameters. Geophysical parameters and data such as rate of amplitude change, wave impedance, and coherence cube play very important role in the evaluation for disposition of the wells. The success rate for disposition of horizontal wells has been improved.
