摘要 郝家坪南杏6050井区主要为三角洲平原亚相沉积,水上分流河道是本区的主要沉积微相。长2^(1)与长2^(2)顶部的构造面貌具有一定的相似性,发育了多条近东西向的平缓鼻隆构造,整体呈现东高西低的西倾单斜,这些鼻状隆起对油气的富集有一定的影响。本文紧密结合工区开发生产实际,通过对长2层的沉积微相和砂体展布的深入研究,认为研究区沉积微相发育水上分流河道、呈满区砂的特征,鼻状隆起影响油气的富集。 The Nanxing 6050 well area in Haojiaping is mainly delta plain subfacies,and the subaqueous distributary channel is the main sedimentary microfacies in this area.The structural features of the top of Chang 2^(1) and Chang 2^(2) are similar to some extent.A number of nearly east-west gentle nose uplifts have been developed,and the overall appearance of the west-dipping monocline is high in the east and low in the west.These nose uplifts have a certain impact on the enrichment of oil and gas.This paper closely combines the actual development and production of the work area,and through in-depth research on the sedimentary microfacies and sand body distribution of the Chang 2 layer,it is believed that the sedimentary microfacies in the study area develop the characteristics of water distributary channels and are full of sand,and the nose uplift affects the enrichment of oil and gas.
