摘要
合理井网密度及极限井网密度的确定是低渗透油田开发的一个重要问题。为此,以采收率与井网密度关系式为基础,考虑油田开发期限内原油销售收入的将来值、开发投资的将来值和开发期限内维修管理费用的将来值,利用投入和产出的平衡关系,得到了涉及水驱油效率、最终采收率及油藏参数等多因素条件下的低渗透油田合理井网密度及极限井网密度的计算方法。利用该方法对朝阳沟油田朝948区块的合理井网及极限井网密度进行了预测,计算结果表明,该方法能够满足油田需要,为油田加密确定井网密度大小提供理论依据。
How to identify rational and ultimate well spacing density has always heen a headache during the development of low penneability reservoirs, Based on the correlation between recovery factor and well spacing, a rational and ultimate well spacing density calculation method in particular for low permeability reservoirs involving influential factors of water flooding efficiency, ultimate recoxery and reservoir parameters is proposed herein, using equilibrium relationships of input and output, considering future values of crude oil sales revenue, investment and maintenance cost within oil field development period. Tire method is applied to Block Chao-984 in Chaoyanggou Oil Field for rational and ultimate well spacing density prediction. Result shows that the method is feasible for the oil field and would provide theoretical support to well pattern infilling.
