松滋油田复Ⅰ断块红花套组油藏开发技术政策研究

Development Technologic Policy Research for Honghuatao Reservoir of Fault Block Fu Ⅰ in Songzi Oilfield

松滋油田复Ⅰ断块红花套组油藏具有砂体厚度大、低孔、特低渗且具有一定底水能量的特点,针对该油藏的特殊性,以精细三维油藏模型为基础,利用油藏数值模拟技术,通过建立概念模型以及典型实体模型对该油藏的开发技术政策进行优化,最终优选方案设计总井数24口,其中新井13口,包括2口直井、5口水平井共7口油井,预计前3年平均年产油4.63×104t。

Honghuatao Reservoir in Songzi Oilfield had the characters of bigger sand thickness,low porosity,extra-low permeability and with some bottom water.In allusion to the characteristics stated,based the three-dimensional fine reservoir model,the reservoir simulation technology was used.In combination with orthogonal testing design method,the development technologic policy is optimized by building the conceptual model and typical reservoir model,by which 24 wells are optimized which include 13new wells,2vertical wells,5horizontal wells,the predicted average annual oil production is 4.63×10 4 t in the first three years.
