“十二五”以来,胜利油区新增探明储量中,深层特低渗透油藏比例逐年加大,至2015年已达到近50%,是未来胜利油田主要的开发接替阵地。该类储层渗透率低,导致油井投产产量低、递减快、注水补充能量困难;同时,储量丰度低,为增大单控储量、减少井数及投资,开发过程中,往往采用较大的注采井距,进一步加剧了注水的难度。针对该矛盾,胜利油田研发形成了仿水平井开发技术,本文以渤南油田义104块深层特低渗透砂砾岩油藏为例,在开发方式、开发层系、布井范围、井型以及井网井距等方面进行了开发技术政策界限论证,为同类型油藏的开发提供借鉴。 Since the “12th Five-year Plan”, the proportion of newly discovered ultra-low permeability reservoirs in Shengli Oilfield has been increasing year by year and has reached nearly 50% by 2015, which is the main development successor position of Shengli Oilfield in the future. Due to the low permeability of such reservoirs, the output of oil wells is low, the delivery rate is decreased rapidly, and the water recharge is difficult. At the same time, the reserve abundance is low. In order to increase single-control reserves and reduce wells and investment, Of injection well interval, further exacerbating the difficulty of water injection. In view of this contradiction, the research and development of Shengli Oilfield formed a horizontal well development technology. This paper takes the Yixian 104 deep ultra-low permeability gravel reservoir in Bonan Oilfield as an example. The development pattern, development strata, well spacing, well pattern and well pattern Network well spacing and other aspects of the development of technology policy boundaries demonstration for the same type of reservoir development to provide reference.
