摘要
随着勘探程度的不断提高和勘探领域的不断延伸,我国陆上油气勘探已经进入了一个岩性油气藏勘探和构造油气藏勘探并重的新阶段,寻找小幅度构造油气藏、老区滚动扩边以及岩性地层油气藏成为主要勘探对象。本研究区受岩性和构造双重因素控制,岩性油气藏储层发育区主要集中在构造的翼部、深凹区、斜坡区。因此,查明该区地质构造特征、储层的岩性、几何形态、物性参数及含油气性,成为储层预测的主要任务。
本文针对该区三维地震资料品质差,储层横向变化快,较大程度地制约区域构造解释精度,储层段较薄等预测难点,采用垂直地震剖面法提取可靠的速度参数,对层位进行了准确标定,极大提高了地震资料处理解释精度,查明了该区构造演化特征。采用测井约束反演方法大大提高了储层反演的精度,预测了目标区储层的空间分布形态及分布规律。利用VSP测井资料及地震合成记录建立测井层序与地震层序之间的关系,分析沉积环境,建立沉积相模式,得出沉积体系展布特征。经过对整个工区的构造、反演、沉积储层等分析得出,该区发育三个有利储层,最终预测结果良好,圈闭内具有一定的石油储量,为以后的勘探工作提供了依据。
With the increasing level of exploration and the continuous extension of the exploration area, China's onshore oil and gas exploration has entered into a entered a new phase that oil and gas exploration phase of both, Find minor structural reservoirs, old liberated Rolling Extension and stratigraphic reservoirs become a major exploration targets. The area affected by two factors control the lithology and structure, lithologic reservoir development area mainly concentrated in the structure of the wing, furrow area, slope area. Therefore, identify characteristics of the geologic structure, lithology, geometry, physical parameters and hydrocarbon potential, to become the main task of reservoir prediction.
In this paper, three-dimensional seismic data of poor quality in the area, Rapid lateral variation of reservoir, A large extent on regional tectonic interpretation accuracy constraints, Prediction of reservoir thin so difficult, the use of vertical seismic profile the speed of extraction of reliable parameters of layers were accurate calibration, which greatly improves the accuracy of seismic data processing and interpretation, to identify the tectonic evolution of the area. Use of constrained inversion method greatly improves the accuracy of reservoir inversion to predict the target area and spatial distribution of reservoir distribution. Use of synthetic VSP logging data and seismic records to establish log sequence and the relationship between seismic sequence analysis sedimentary environment, the establishment of sedimentary facies pattern, distribution of depositional systems derived features. After the construction of the entire work area, inversion, sedimentary reservoir draw such analysis, the three favorable reservoir development area, the final prediction with good results, traps have some oil reserves for the future provides the basis for the exploration work.
