英台-四方坨子地区油气藏非常复杂,具有构造幅度低、断层分布复杂、流体识别困难、油藏类型多样的特点。针对复杂油气藏实际情况,利用三维构造精细解释技术对构造和断层进行了精细描述,利用层序地层学原理和沉积微相技术进行了储层精细描述,利用多信息流体识别方法解决了该区流体识别的难点。对该区复杂的油气藏有了全面的认识,明确了油藏控制因素和油藏类型,实现了该区储量和产量大幅度增长。
The reservoirs in Yingtai and Sifangituozi area are very complicated with the features of low tectonic amplitude, complex fault distribution, difficult fluid identification and diverse reservoir types. According to the actual situation of complex oil and gas reservoirs, the structure and fault are elaborately described by using the three-dimensional fine structure interpretation technique, and the reservoir is finely described by the sequence stratigraphy principle and sedimentary microfacies technology. The multi-information fluid identification method is used to solve the problem Difficulties in fluid identification. This area has a comprehensive understanding of complex reservoirs, defined reservoir control factors and reservoir types, and realized a substantial increase in reserves and output in the area.
