3、發(fā)揮其效用，改善鉆井液性能，如 果沒有充分剪切，聚合物在第一次循環(huán)中就可能堵塞振動(dòng)篩網(wǎng)， 損失大量的聚合物，增加鉆井成本，并且還可能使鉆井液中的大 尺寸的固相顆粒變硬而難以除掉；在完井液中，由于沒有充分剪 切，聚合物會(huì)產(chǎn)生許多“魚眼”。這些“魚眼”會(huì)傷害地層，使地 層滲透率降低，油氣層減產(chǎn)。經(jīng)過事實(shí)證明WJQ5 6 J-10 剪切泵具有優(yōu)良的性能，它能為高分子聚合物（也能為粘土）迅 速水合提供高度的剪切，解決聚合物（或粘土）在鉆井液中或完 井液中因水合不好而存在的突出問題。同時(shí)，使用 WJQ5 6 J-10 剪切泵能使聚合物用量減少15%以上，膨潤(rùn)土 用量減少30%以上，并且改善了泥餅和液流損

4、失，降低鉆井液剪 切比速率，提高凝膠強(qiáng)度，達(dá)到了國(guó)外同類產(chǎn)品的先進(jìn)水平，其 軸封結(jié)構(gòu)更可靠，使用維護(hù)更方便。2 .原理WJQ5 6 JC-10剪切泵密封采用了非?？煽康臋C(jī)械密 封，保證無泄漏。泵內(nèi)部配有一個(gè)300mm不銹鋼渦輪（其上有 導(dǎo)葉、葉輪、44個(gè)噴嘴、4個(gè)收集室），及一個(gè)剪切板，能夠 產(chǎn)生超過s的小端剪切（液體剪切），當(dāng)液流通過剪切泵時(shí)， 有一半（50%）的液體在渦輪收集室的強(qiáng)力推進(jìn)下將被剪切兩 次。該渦輪剪切泵安裝在一專用底座上，并用皮帶輪、窄V 帶和55KW/75kw防爆電動(dòng)機(jī)驅(qū)動(dòng)，與剪切泵配套使用的還有一 個(gè)尺寸適合的ZHP150混合漏斗，這樣組成了一個(gè)完善的剪切 及水合作用系統(tǒng)

5、。由于該泵軸封的改進(jìn)，使其壽命大大提高。如遵循該泵安裝及特殊條件應(yīng)用的規(guī)則，將進(jìn)一步提高其 性能。本公司將對(duì)在油田及工業(yè)應(yīng)用中有利于提高該泵性能的一 般及特殊建議進(jìn)行處理。注意：該泵不能用于活性泥漿系統(tǒng)，因?yàn)橄到y(tǒng)中的鉆井固 體及重晶石，它們?cè)谑艿郊羟袝r(shí)將很快損壞該泵。原理如圖一:圖一 WJQ5 6 JC-10 剪切泵原理圖聚合物流體從V流道進(jìn)入，并以平行與剪切板P的方向抽 送，收集室內(nèi)液流量的50%通過44個(gè)噴嘴N射出，并以高速 沖擊剪切板P,然后在M處90 方向進(jìn)入泵的蝸殼收集室?？?流V及射流N沿著剪切板流動(dòng)到達(dá)剪切盤的尖端T,在尖端有 許多牙齒，高速旋轉(zhuǎn)的牙齒使聚合物（或粘土）再一次被剪

6、切。 這樣就完成了聚合物（或粘土）高度剪切而迅速水合。3 .型號(hào)說明WJQ 5"6 J-10渦輪名義直徑（英寸）密封形式泵進(jìn)口直徑（英寸）泵出口直徑（英寸）渦輪剪切泵4,性能表（表1）型號(hào)流量揚(yáng)轉(zhuǎn)速效汽蝕功率（kw）(m3/ h)程(m)(r/mi n)率(%)余量(m)功軸率配套功 率WJQ5 6 J-101553222802834655WJQ56 J-101553222802834675H|mlE|%lQUZOf 1 J.Z-Z Qr 1/ r- 一 _ .H-»i66Z (;L II一一_6 m4 vNt60C A二 ncROAftz O IIO.PalKwl二 n
