Having fluid columns inside a fixed width container makes the template very flexible . if we add width changer buttons , we only need to change one value 在可流動(dòng)列內(nèi)部嵌入一個(gè)固定寬度容器會(huì)增加延展性,如果我們加入改變寬度的按鈕,我們只需要改變一個(gè)寬度值就成了。
In chapter three , in order to simulate the actual drilling fluid column pressure and to supply the extreme high pressure drilling circulating fluid for the device , the high pressure circulating fluid simulating system has been designed based on the experience of drilling fluid circulating system in the wellside . to purify the drilling fluid , the high pressure desander has been designed 第三章為模擬實(shí)際鉆井的液柱壓力,并為整個(gè)模擬鉆井裝置提供超高壓循環(huán)鉆井液,在借鑒了鉆井現(xiàn)場的鉆井液循環(huán)系統(tǒng)經(jīng)驗(yàn)的基礎(chǔ)上分析研究了鉆井液高壓循環(huán)系統(tǒng),并配套設(shè)計(jì)了高壓除砂器,以達(dá)到凈化該系統(tǒng)中鉆井液的要求。
Abstract : tight trips often occur for hole undergauge during drilling in east sichuan oilfield . the paper analysis the causes of hole undergauge , proposes preventive and treatment measures which are to optimize design from geologic structure features , to use suitable fluid column pressure , to select different drilling fluid types , to adopt advanced drilling technology and perfect field technical management . therefore , good economic benefit will be obtained 文摘:川東構(gòu)造在鉆探作業(yè)中因井眼縮徑造成起下鉆的阻卡時(shí)有發(fā)生,文中對(duì)造成井眼縮小的原因進(jìn)行分析并劃分為五類因素,提出應(yīng)在地質(zhì)構(gòu)造特征方面優(yōu)化設(shè)計(jì),采用合適的液柱壓力,選擇不同的鉆井液類型,使用先進(jìn)的鉆井工藝和完善現(xiàn)場技術(shù)管理等措施進(jìn)行預(yù)防和處理,將取得重大的經(jīng)濟(jì)效益。
