苏里格气田苏20区块开发效果评价

苏里格气田山1、盒8气藏为典型的低孔、低渗、低丰度、强非均质性的岩性气藏,表现出单井产量低、控制储量少、初期稳产较难、开发难度大等一系列开发特征。从井网井距、合理配产等开发指标对区块开发效果影响方面进行评价,为气田下一步滚动建产、扩大开放规模提供依据,为实现气田的稳产和合理、高效开发奠定基础。

Evaluation for Development Effect in Block Su 20 of Sulige Gas Field

Hill 1 and box 8 gas reservoirs in the Sulige gas field are typical lithologic one as low porosity,low permeability,low abundance,and strong heterogeneity,have a serious of developing features of being low output of a single well,little controlled reserve,much difficult to keep the initial stability,hard to develop.From the well spacing,reasonable allocation production development indexes,development effect is valuated,which provides the basis for the next rolling productivity construction,expanding the opening size,and makes foundation for the stable,reasonable and efficient development of the gas field.
