【摘要】 在油田开发过程中，在特定的地质条件下，采用什么样的开采技术，会直接影响到油田最终的经济效益。多分支井开采技术一方面能最大限度地沟通油气藏，增大泄油面积，提高油藏的动用程度，增加油气产量，另一方面又能降低油气藏开采的综合成本。特别是对于大庆油田的多层油气藏以及老油田挖潜改造，多分支井技术更具有广阔的应用前景。 本文首先介绍了分支井的基本特征并对其在大庆油田的应用前景作了分析，然后定量分析了多分支井的产量及其成本，最后建立了多分支井经济效益静态和动态模型，并对影响多分支井经济效益的因素进行了分析。本论文的成果为多分支井技术的经济可行性研究提供了理论分析工具。更多还原

【Abstract】 In oil field developing process, developing technique will directly affect economic benefit in oil-field under the particular condition of geology. Multilateral wells technique on the hand can enlarge the drainage area, increase the exploitation degree and oil yield, on the other hand lower the cost of development. Multilateral wells have the advantage in drilling many oil layers and enhancing oil recovery of the exhausted oil-field. Multilateral wells technique has the vast and applied foreground very much.In this thesis, firstly, the basic characteristics were introduced of the multilateral wells and the applied foreground were analyzed in Daqing oil field. Secondly, making the quantitative analysis to yield and costs of multilateral wells. Lastly, the static and dynamic economic benefit models of multilateral wells were established and the influence factors to the economic benefit of multilateral well were analyzed. These are the theories tools for the research of the economic benefit and the application of multilateral wells.更多还原
