裂缝型碳酸盐岩储层由于极高的孔渗性,是最为有利的油气勘探目标之一.这类储层预测难度较大,特别是对于石膏和盐层非常发育的碳酸盐岩储层.本次研究从裂缝型碳酸盐岩的发育特征研究入手,分析地震识别此类储层的可行性.优选多种地震地质储层预测方法,针对土库曼斯坦阿姆河右岸区块霍贾姆巴兹三维区的储层特点,开展了一系列的含气储层预测研究.主要应用了相干分析,像素成像技术,叠前各向异性裂缝检测,构造应力场分析,蚂蚁追踪算法等技术.预测了研究区有利的含气储层发育带,预测储层与钻探结果符合程度较高.形成了裂缝型碳酸盐岩储层预测技术系列,在海外气田勘探实践中发挥了重要的作用.
Fractured carbonate reservoirs are one of the most favored targets for hydrocarbon exploration because of their high porosity and permeability, which are difficult to predict, especially for carbonate reservoirs, where gypsum and salt are well developed This study started from the study of the developmental characteristics of fractured carbonate rocks and analyzed the feasibility of identifying such reservoirs by seismic.A variety of seismic geological reservoir prediction methods were optimized.According to the analysis on the right bank of Armen River in Turkmenistan, A series of gas reservoir prediction studies have been carried out.Main applications include coherent analysis, pixel imaging technology, prestack anisotropic fracture detection, tectonic stress field analysis and ant tracking algorithm Predicting favorable zone of gas-bearing reservoirs in the study area and predicting that reservoirs are in good agreement with drilling results, a series of prediction technologies of fractured carbonate reservoirs have been formed, which play an important role in the exploration of overseas gas fields .
