底水油藏开发毕业论文

摘 要

底水油藏在我国油藏中占很大的比例，其储量相当丰富。除了有大量的天然底水油藏外，随着油田进入二次开采，更多油田的开发特征不断趋向于底水类型的油藏。本课题以底水油藏为对象，采用石油地质方法和油藏工程方法，对油田开展注采动态综合研究。

对试油、试采效果进行评价和总结，在此基础上，对注采井网适应性、注水开发效果及技术政策界限做进一步的分析研究，最终形成切合目前油藏实际，可操作性较强的注采井网，通过该成果的实施，完善和优化油田注采系统，补充和保持地层能量，提高主力油砂体水驱控制程度和水驱动用储量，提高油田采油速度及油田最终采收率。

II Abstract

Reservoir with bottom water reservoir in China accounted for a substantial

proportion of its abundant reserves. Except the end has many natural water reservoir

outside, with access to the secondary exploitation of oil fields, more oil fields to

develop the characteristics of continuous trend in the type of bottom water reservoir.

Subject to the bottom water reservoir for the object, the use of petroleum geology and

reservoir engineering methods, to carry out oil field injection-production Dynamic

comprehensive study, and then put forward .

of the test oil ,the effect of the test-mining evaluation and conclusion, on this basis,

the injection-production wells Net adaptability, water effects and technology policy

development boundaries to do further analysis and study, eventually form a reservoir to

meet the current reality, operability than strong network of injection and production

wells ,through the implementation of the outcome, improve and optimize the oil field

injection-production system, to supplement and maintain the formation energy ,the main

oil sands enhance body control the degree of water flooding and water-driven by

reserves ,improve the speed and oilfield oil field finally adopted yield.

Key words: bottom water reservoir; injection-production performance;

development effect 底水油藏开发毕业论文
