塔河油田3区石炭系超深储层油藏描述研究
|
摘要
塔河油田3区石炭系储层为一套浅海~滨海相碎屑岩沉积层系,主含油层位为卡拉沙依组砂泥岩互层段,发育有不等厚薄互层状油藏,具有埋藏深、单层厚度小、砂体分布不稳定、油水层相间分布、成藏条件复杂等特点。针对含油储层薄、砂体追踪对比困难等问题,在提高地震分辨率基础上,通过井震标定及三维地震精细解释,进行了含油砂体展布研究。利用拟声波地震反演预测技术,进行了储层空间展布特征刻画,提高了薄砂体识别能力。在有利的储层分布区内,针对测试高产油气层,通过油藏综合评价及进行滚动部署,取得了较好增储上产效果。
The carboniferous reservoir of the third area in TaHe oilfield is a shallow sea and coastal clastic facies strata,The main oil-bearing layer is Kalashayi sand-shale sequence and growing inequality-thickness interbedded reservoir.The reservoir is characterized by the ultra-depth,small formation thickness,unstable sand distribution,oil-water coherent distribution,complex forming conditions,etc.Based on the problems such as thin oil reservoir and difficulties for tracking sand body,proceeding research on oil sand structure are carried out by wells calibration and three-dimensional seismic interpretation with the increasing of seismic resolution.The pseudo-wave seismic inversion technology is used to proceed reservoir space distribution features and improve the ability to identify the thin sand body;In the favorable reservoir distribution area,the integrated reservoir evaluation and conduct rolling deployment based on above techniques achieve good results and increase reserves and production.
