分层开发油藏见水原因分析及稳产技术研究

Layered development of the water reservoir stability analysis and research

采油三厂分层开发油藏主要分布在虎狼峁、吴仓堡、盘古梁等三叠系油藏储层叠加区,日产油占采油三厂总产量的24%,地质储量占三叠系油藏储量的8%,分层开发油藏的产量与储量在采油三厂中的地位日益凸现。但近年来开发的虎狼峁等分层开发油藏在开发过程中不同程度的见水,且见水井不断增多,同时由于产液结构不清等因素,导致分层开发油藏开发难度日益加大,严重的影响着油田的高效开发。

Production factory lay ered development of reservoirs are mainly distributed in HuLangMao hilly,Wucangbao,such as Pan Gu Liang Triassic reservoirs stack,the three oil-producing plant of the oil output of 24%of the Triassic geological reserves 8 percent of reservoir reserves,the development of layered reservoir of oil production and reserves in the position of the three plants growing highlights.But in recent years,such as the development of HuLangMao hilly tiered development in the reservoir in the process of developing different levels of the water,and wells continue to see increased,and because of the structure of production factors such as unclear,leading to the development of layered difficulty growing reservoir development The serious impact on the efficient development of oil fields.
