【摘要】：羊二庄油田位于黄骅坳陷羊二庄鼻状构造东北部,为赵家堡断层下降盘上的一个逆牵背斜(穹隆背斜)构造。钻探证实该区发育第四系平原组、上第三系明化镇组和馆陶组、下第三系东营组;主要含油层系为上第三系明化镇组和馆陶组。油田勘探初期是按构造找油的思路,围绕中央隆起带上背斜、断鼻构造进行勘探开发。从目前的钻探现状看,构造带主体已全面开发,必须按照岩性油气藏勘探的思路,沿构造周边实施滚动扩边外,寻找河道砂体岩性油气藏,在羊二庄北斜坡钻探的庄83井,在明化镇见到良好的油气显示,展示了斜坡区岩性油气藏勘探的前景。羊二庄地区受物源、古地形、构造背景的影响发育河流相沉积体系,属于砂泥岩储盖组合,寻找河道砂体,进行钻探,扩大含油面积,提高油气储量。首先多井联合标定,井震吻合,搞清河道砂体地震反射特征,利用重新处理的新资料,进行精细构造解释,在正确的地质框架上进行储层预测,采用多属性联合反演,寻找敏感参数,结合地层切片、三维可视化、种子点自动追踪等技术,在羊二庄地区发现不同层系50多条河道砂体,最后分析河道砂体的油源条件、油气运移方式、盖层和侧向封堵条件,并利用频率衰减属性进行含油气预测,优选多口井位,指导勘探部署。
[Abstract]:Yangerzhuang oilfield is located in the northeast of Yangerzhuang nose structure in Huanghua depression, which is a reverse traction anticline (dome anticline) on the descending plate of Zhaojiapu fault. The development of Quaternary plain formation, Upper Tertiary Ming Hua Zhen formation and Guantao formation, and Lower Tertiary Dongying formation is confirmed by drilling, and the main oil-bearing strata are Upper Tertiary Minghua Zhen formation and Guantao formation. In the early exploration of oil field, the exploration and development of the anticline and fault nose structure in the central uplift zone were carried out according to the idea of structural oil exploration. In view of the present drilling situation, the main body of the structural belt has been fully developed, and it is necessary to carry out rolling expansion along the periphery of the structure to search for lithologic reservoirs in the channel sand body in accordance with the idea of lithologic oil and gas reservoir exploration, and to drill well Zhuang83 on the northern slope of Yangerzhuang. A good oil and gas display is seen in Minghua town, which shows the prospect of lithologic oil and gas exploration in slope area. The fluvial facies sedimentary system is developed in Yangerzhuang area under the influence of provenance, paleogeography and tectonic background, which belongs to the combination of sand and mudstone reservoir and cap, looks for channel sand body, carries out drilling, expands oil-bearing area and improves oil and gas reserves. First of all, multi-well joint calibration, well seismic coincidence, clear channel sand body seismic reflection characteristics, using reprocessed new data, fine structure interpretation, reservoir prediction on the correct geological framework, using multi-attribute joint inversion, Searching for sensitive parameters, combining the techniques of stratigraphic slicing, 3D visualization and automatic tracing of seed points, more than 50 river channel sand bodies with different strata are found in Yangerzhuang area. Finally, the oil source conditions and oil and gas migration modes of channel sand bodies are analyzed. The caprock and lateral plugging conditions are used to predict oil and gas with frequency attenuation attribute, and multiple wells are selected to guide exploration and deployment.
