通过室内实验、油藏模拟和油藏工程研究，确定了靖安油田长6油藏合理的井网、井距、射孔井段、注气方式、注气速度等油藏开发技术政策。通过3年多的注气矿场试验，探讨了特低渗透油藏注气开发的适应性和可行性。分析总结了靖安油田注气开发过程中产油量、含水率、戈尔比、采出液面、地层压力、伴生气组分等指标的变化规律及影响注气开发效果的因素。提出了油田早期注水开发的合理界限或技术政策，以及调整实施方案的建议。
Technical policies of reservoir development such as the rational well pattern, well spacing, perforation interval, gas injection mode, gas injection speed for Chang 6 reservoir in Jingan oil field are determined in this paper, through indoor experiment, oil reservoir simulation, and reservoir engineering study. As a result of more than 3 year field test of gas injection, adaptability and feasibility of extra low permeability reservoir development by gas injection are discussed. The authors analytically sum up the changing laws of indexes such as oil production, water cut, GOR , producing fluid level, formation pressure, and component of associated gas, and factors influencing the results of Jingan oil field development by gas injection. Rational limits or technical policy for water flooding the oil field at early stage, and advices of adjusting the implementation plan are put forward in the paper.
