The Research Of Economic Benefit On Multilateral Wells

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.
