孤东油田七区西5~4-6~1区块整体调剖综合决策技术现场应用研究

Field Application of Integral Profile Control of Members 5~4-6~1 in West Block of Region 7 in Gudong Oilfield

利用油藏理论和数值计算方法对调剖的选井、堵剂、施工参数与效果评价等进行了研究 ,实现了区块整体调剖选井决策、堵剂决策、施工设计、效果评价的一体化。运用该决策技术对孤东油田七区西 5 4 -61区块进行治理 ,使该区块开发效果明显改善 ,日增油 69.9t,综合含水下降 0 .2 % ,提高采收率 4 .0 5 % ,增加可采储量 738× 1 0 3 t。

Well selection, plugging agent,operational parameters and effect evaluation of the profile control technique are studied by using the reservoir engineering theory and numerical calculation, the integration of well selection decision, decision of plugging agent, design of operation and result evaluation of the integral profile control is realized Members 5 4 6 1 of the block of region 7 in Gudong oilfield are controlled by using the decison technique, by which development effect is improved evidently,oil production of 69 9 t/d is raised, 0 2% of the integrated water cut is reduced,4 05% of oil recovery is enhanced,738×10 3 t of recoverable reserves are added,effect of the technique is obvious
