2、重要的意義。本文主要討論常規(guī)油藏井網(wǎng)部署形式和低滲油田中的井網(wǎng)部署基本方法,在此基礎(chǔ)上,運(yùn)用數(shù)值模擬等方法對(duì)坪北油田SP199井區(qū)、薛岔油田的井網(wǎng)部署進(jìn)行評(píng)價(jià),提出了具體可行的實(shí)施方案。研究表明:就坪北油田SP199井區(qū)而言,采用棱形反九點(diǎn)井網(wǎng)、井距為100m~160m較合理;薛岔油田長(zhǎng)61油藏亦可采用棱形反九點(diǎn)注采井網(wǎng)、井網(wǎng)密度控制在15.35口/km2、井距500m、排距130m為最合理的井網(wǎng)系統(tǒng)。關(guān)鍵詞:井網(wǎng)部署;井網(wǎng)密度;坪北油田;薛岔油田21西安石油大學(xué)成人高等教育畢業(yè)設(shè)計(jì)(論文)SimplyDiscussionsonthe
