本文应用趋势面分析的方法，对YG气田的TB、T3构造面，TA-T3层厚度分别作了趋势值和剩余值分析，并结合已有油气田勘探地质资料作了综合分析，探讨了气井的分布、产能和沉积环境与构造位置、剩余值的关系。结果表明，已有的气井在构造剩余趋势和厚度剩余趋势等值线图上均有明显的组合特征，气井皆分布在构造正剩余区内，厚度正剩余有助于天然气的富集，构造控制的气井有较高的产能。同时指出构造、岩性在控制油气分布与聚集上所起的作用；划分了构造、构造岩性这两类气藏；提出了未来勘探布井的原则，并对YG地区作了远景划分。
In this paper, trends and residual values of tectonic plane TB-T3 and thickness of TA-T3 in YG gas field are analyzed by trend surface analysis. Combined with the exploration geology data of the existing oil and gas fields, the paper analyzes gas wells Distribution, productivity and sedimentary environment and the location of the relationship between the residual value. The results show that the existing gas wells have obvious combination features on the contours of residual tectonic trend and thickness trend. The gas wells are all distributed in the positive residual zone of the structure and the positive residual thickness contributes to the enrichment of natural gas and the tectonic control Gas wells have higher capacity. At the same time, it points out the role of tectonics and lithology in controlling the distribution and accumulation of oil and gas. It divides the two types of gas reservoirs, such as tectonics and lithology, and puts forward the principle of prospecting wells in the future and makes a long-range division of YG.
