中文摘要：
低渗透油藏受层间储层物性差异的影响,层间动用程度差异大,层间矛盾突出。层间径向钻孔技术是解决层间矛盾的重要技术之一。依据层间均衡驱替的原则,考虑启动压力梯度,应用等值渗流阻力法,建立了径向钻孔长度及分支个数的优化模型,并提出了现场实用的交会图版求解方法。利用油藏数值模拟技术,对优化方法进行了验证,证实了此方法的可行性与准确性。
英文摘要：
During the development of low permeability reservoirs, the degree of multi-layer displacement is quite different and the conflicts between the layers are obvious. The radial drilling technique is one of the useful ways to solve multi-layer conflicts. Using the equivalent seepage resistant methods, considering the starting pressure gradient, according to the muhilayer equilibrium displacement principle, the optimization model of radial length and branch number is established. Simple cross plot method used for the field workers is also presented. Last using the reservoir simulation technology according to the predicted results the above methods are proved to be valid and accurate.
