(1)充氮壓力的計(jì)算

根據(jù)地面溫度,靜液柱壓力和井內(nèi)泥漿溫度查表5確定充氮壓力,為了確定精確的充氮正力,需用內(nèi)插法計(jì)算充氮壓力值。

1)選定與地面實(shí)際溫度最接近的地面溫度的表格。

2)選定與測(cè)試深度的實(shí)際泥漿溫度最接近的表中泥漿溫度。

3)一旦選定了確切表格,且根據(jù)表格確定了泥漿溫度,即可確定用于實(shí)際測(cè)試深度液柱壓力的確切充氮壓力。如果實(shí)際靜液柱壓力與表格中靜液柱壓力不符,可應(yīng)用下列公式去確定與此靜液柱壓力相應(yīng)的充氮壓力:充氮壓力式中Pn――充氮壓力,MPa;

CPh――表中高靜液柱壓力下的充氮壓力,MPa;

CPL――表中低靜液柱壓力下的充氮壓力,MPa;

Ha－一實(shí)際靜液柱壓力,MPa;

(1)選擇與所使用規(guī)格的LPR-N測(cè)試閥相應(yīng)的表格。

(2)選定實(shí)際測(cè)試深度的泥漿溫度與表中最接近的溫度。(3)如實(shí)際靜液柱壓力介于表中兩個(gè)靜液柱壓力之間,則用下列內(nèi)插法公式計(jì)算出操作壓力。操作壓力

式中P1一一操作壓力,MPa;Ph一一表中高靜液柱壓力下的操作壓力,MPa;PL一一表中高靜液柱壓力下的操作壓力,MPa;

RTTS安全接頭可接于循環(huán)閥以上或循環(huán)閥與RTTS封隔器之間。當(dāng)接于循環(huán)閥之上時(shí),可直接與之相連接。當(dāng)接于循環(huán)閥與封隔器之上時(shí),安全接頭的下接頭應(yīng)卸掉并接于安全接頭頂部。這樣,安全接頭底部的扣可直接與封隔器相接。然后循環(huán)閥可直接接在安全接頭頂部接頭上。

正常測(cè)試安全接頭靠張力套不會(huì)倒開(kāi)。一旦發(fā)生緊急情況需要倒安全接頭時(shí),先對(duì)管柱施加壓力使張力套斷開(kāi),保持對(duì)管柱的右旋扭矩并上下運(yùn)動(dòng)即可完全倒開(kāi)。除95/8″RTTS安全接頭每右旋一圈需要三行程外,所有其它規(guī)格的RTTS安全接頭每轉(zhuǎn)一圈需要兩個(gè)上、下行程。(十一)RTTS封隔器1．作用與原理RTTS封隔器與RTTS循環(huán)閥配套使用。由于帶有水力錨是用于措施和擠水泥工作的全通徑卡瓦型封閣器,卸掉水力錨改為測(cè)試接頭可進(jìn)行測(cè)試作業(yè)。RTTS封隔器的作業(yè)原理是:封隔器下井時(shí),摩擦墊塊始終與套管內(nèi)壁緊貼,凸耳是在換位槽短槽的下端,膠筒處于自由狀態(tài)。當(dāng)封隔器下到預(yù)定井深時(shí),先上提管柱,使凸耳到短槽的上部位置,右旋管柱1－3圈,在保持扭矩同時(shí),下入管柱加壓縮負(fù)荷。由于右旋管柱使凸耳從短槽到長(zhǎng)糟內(nèi),加壓時(shí)下心軸向下移動(dòng),卡瓦錐體下行把卡瓦張開(kāi),卡瓦上的合金塊的棱角嵌入套管壁,而后膠筒受壓而膨脹,直到兩個(gè)膠筒都緊貼在套管壁上,形成密封。如果進(jìn)行擠注作業(yè),封隔器膠筒以下壓力大于封隔器膠筒以上靜液柱壓力時(shí),下部壓力將經(jīng)過(guò)容積管傳到水力錨,使水力錨卡瓦張開(kāi),卡瓦上的合金卡瓦牙方向朝上,從而使封隔器牢固地坐封在套管內(nèi)壁上。如果要起出封隔器,只需施加拉伸負(fù)荷,先打開(kāi)循環(huán)閥,使膠筒上、下壓力平衡,水力描卡瓦自動(dòng)收回,再繼續(xù)上提,膠筒卸掉壓力而恢復(fù)原來(lái)的自由狀態(tài),此時(shí)凸耳從長(zhǎng)槽沿斜面自動(dòng)回到短槽內(nèi),錐體上行,卡瓦隨之收回,便可將封隔器起出井筒。2．結(jié)構(gòu)RTTS封隔器由J一槽機(jī)構(gòu)、機(jī)械卡瓦、膠筒和水力錨組成(圖4一12)。膠筒密封部分由上通徑規(guī)環(huán)、2個(gè)膠筒、隔環(huán)、下通徑規(guī)環(huán)組成。機(jī)械卡瓦部分由機(jī)械卡瓦本體、上心軸、卡瓦上動(dòng)銷(xiāo)、6個(gè)機(jī)械卡瓦片、帶帽螺釘、開(kāi)口環(huán)箍組成。J一槽換位機(jī)構(gòu)由4個(gè)摩擦塊、16片摩擦塊彈簧、4個(gè)固定環(huán)、摩擦套筒和下心軸組成。3．技術(shù)規(guī)范見(jiàn)表13和表14。表4－13RTTS封隔器技術(shù)規(guī)范總成號(hào)套管尺寸及重量摩擦塊處外徑內(nèi)徑mm長(zhǎng)度mm連接扣型696.52735″－15－18#120.945.71167.9上端33/32″－10N－3母扣下端87/8”″EUE8牙油管公扣596.538251/2″－13－20#133.448.31178.1上端31/2″－8N－M母扣下端27/8”″EUE8牙油管公扣696.57817″－17－38#61.01323.3上端45/32″－8N－M母扣下端27/8”″EUE8牙油管公扣696.578997″－17－38#61.01005.1上端31/8″－8N－M母扣下端27/8″EUE8牙油管公扣696.608395/8″－29.3－53.5101.61973.8４1/2″API內(nèi)平扣696.6089995/8″－29.3－53.5101.61605.5上端３1/2″API貫眼母扣下端４1/2″API內(nèi)平公扣表4－14RTTS封隔器膠筒和通徑規(guī)環(huán)技術(shù)參數(shù)套管尺寸及重量交通件號(hào)邵氏硬度膠筒外徑mm通徑規(guī)外徑mm隔環(huán)外徑mm5″17－18#696.52781696.52782696.52789696.527845075909599.1103.193.551/2″13－20#696.53381696.53389696.53383696.5338275909585113.0115.6101.67″32－38#696.57381696.57382696.57383758595172.7143.5137.27″17－26#696.57985696.57086696.57087696.5708850708595151.1152.4137.27″23－29#696.5739190144.8146.1137.27″32－38#696.5778290142.7143.5137.295/8″29.3－43.5#696.60381696.60382696.60383696.6038450708090207.8209.6198.195/8″47－53.5#696.60391696.60392696.60393696.60394507080201.9209.6198.1(十二)全通徑壓力計(jì)托筒
