Xindian oilfield in 1996 into the development, in order to further improve the injection production well pattern, has experienced expansion of encryption, mutually explanatory and supplementary measures of adjusting hole, cut-off 2010 comprehensive water 59.02%, and gradually into the in high water cut stage, in the development process are also different degrees of exposed many development problems. A store of oil gas water distribution is complex, the oil, gas and water judgment difficulty is greater; the second is Putaohua reservoir with edge water energy is sufficient, the edge water advancing fast, water cut rising fast; three is affected by the Gaotaizi reservoir water flooding development effect of small scale, low degree of effect; the fourth is a high proportion of inefficient wells and oilfield development effect is poor.
The Xindian oilfield actual development process encountered problems, the author analyzes the development rules and development process in the existing problems and the injection production system adjustment is necessary, in terms of the number of the oil and water well ratio, formation pressure, water flooding control degree, wells efficiency degree, edge and bottom soaked education degree and edge and bottom water propulsion speed of Xindian field of detailed analysis and demonstration, the injection production system to adjust the necessity and feasibility of, by adjusting injection production improve the oil and water migration, alleviate water cut rising courier, slowing the natural decline rate, increase the output of crude oil. According to the geological
Xindian oilfield reservoir characteristics and well developed network form,Is proposed in this paper Xindian oilfield injection production system adjustment principle, hole filling principle, the water distribution principle, and according to adjust to the principle of design and development program, and index prediction and evaluation of economic benefit, through the study found, determine the injection and production adjustment methods to improve store oil field development effect has very good applicability, the method at the same time, this paper determines the adjustment for the other during the period of high water cut oilfield has certain guidance and reference significance. Keywords:
Xindian oilfield injection production system;; adjustment scheme; water distribution principle; the principle of reperforating
