壓裂返排液處理技術(shù)的現狀、發(fā)展及新工藝_陜西歐菲德環(huán)?？萍加邢薰綺陜西歐菲德環(huán)?？萍加邢薰?/title> <meta name="keywords" content="" /> <meta name="description" content="油田采油壓裂技術(shù)是指利用壓力將地層壓開(kāi)，產(chǎn)生裂縫，并用適量的支撐劑（通常是具有一定粘度的砂粒）將裂縫支撐起來(lái)，以減少流體流動(dòng)阻力的一種增產(chǎn)增注措施。壓裂施工成功的關(guān)鍵是配置出油量的壓裂液體系，用于攜帶砂粒進(jìn)入地層。自從上世紀五十年代出開(kāi)始用于造縫增產(chǎn)以來(lái)，其體系發(fā)生了較大的改變。早期壓裂液體系是向汽油中添加粘性流體用于壓開(kāi)裂縫的油基壓裂液。但是該類(lèi)型壓裂液體系在高溫油井中粘度變小，大大降低施工效率"
