陵76区块经过十多年的开发,目前已进入特高含水开发期,注采矛盾突出,主力油层水淹严重,层间差异大。本文阐述了通过构造精细解释及小层精细对比,重新认识构造,并对区块油层重新划分,落实小层砂体,同时应用油藏数模和精细动态分析相结合的方法进行区块剩余油分布规律研究。根据各小层出力状况及平面、层间剩余油分布规律,对陵76区块细分开发层系,提出合理的调整方案,通过钻调整井、层系调整等措施完善注采井网,提高陵76区块开发效果。
After more than 10 years of development, the Tomb of Block 76 has entered the development period of ultra-high water-cut. The contradiction between injection and mining is prominent. The main reservoir is flooded severely and the difference between layers is large. In this paper, we elaborate on the re-recognition of tectonics by means of fine interpretation and fine contrasting of small layers, and the rezoning of block reservoirs to implement small sand bodies. At the same time, the residual oil from blocks Research on Distribution Law. According to the output status of each small layer and the distribution rules of remaining oil in the plane and layer, a reasonable adjustment plan is proposed for the subdivision development strata of the Mausoleum 76 so as to improve the well pattern of injection and production by means of adjusting the well and adjusting the strata. Tomb 76 block development effect.
