-但需要最長的時間和最大程度的應用井口裝置。鉆井液在第一個循環(huán)周內未加重，因此立壓不變(或初始與終了循環(huán)壓力相等)，同時第一循環(huán)周結束，關閉節(jié)流閥時，套壓應該等于立壓。4、先循環(huán)排出受侵污的鉆井液，然后邊加重鉆井液邊循環(huán)壓井法。這種處置方法既復雜又需要時間更長。附件1-13：井壓井施工單年月日井號井隊填表人井深H0M垂深H1M原漿密度γMg/m3鉆進排量QL/S低泵沖泵壓PCiMPa漏失壓力梯度GfMPa/M壓井排量QkL/S套管鞋深度hM鉆柱內容積系數VAL/M鉆頭位置斜深HM壓井附加密度γeg/cm3環(huán)空容積系數VBL/M鉆頭位置垂深H2關井立壓PdMPa關井套壓PaMPa溢流量△VM3地層壓力P=Pd+0.0098γH1e=MPa壓井泥漿密度γ1=γ+Pd/(0.0098H1)+γe=g/cm3初始循環(huán)立壓PTi=Pd+PCi=MPa終了循環(huán)立壓PTF＝γ1/γ*Pci=MPa井筒容積Vj=H0D2/2000=M3加重材料用量W=V1*γ0(γ1-γ)/(γ0-γ1)=噸重漿到鉆頭時間T1=VAH/(60*QK)(分)重漿從鉆頭到井口時間T2=VBH/(60*QK)(分)壓井總時間T=T1+T2(分)備注：γ0：加重材料比重(石灰石2.42，重晶石4.2)，D:井眼直徑，″(81/2″井筒容積36L/M，91/2″井筒容積45L/M,5″鉆桿外容積13L/M,5″鉆桿內容積9.2L/M)，V1：所需加重量，一般所需加重量按井筒容積的2倍計算，即V1=2Vj=H0D2/1000。設計人：審批人：工程師法壓井步驟1.在關井套壓小于最大允許關井套壓值的情況下，繼續(xù)關井，先加重泥漿，再循環(huán)壓井(工程師法)。組織一切力量迅速加重配漿是關鍵。2.以進入目的層后最后一次低泵沖試驗的泵沖及排量，循環(huán)注入加重泥漿；在加重泥漿到達鉆頭的過程中，調節(jié)節(jié)流閥使立壓由初始循環(huán)值下降到終了循環(huán)值(加重泥漿低泵沖泵壓)，使套壓值保持不變。3.當加重泥漿到達鉆頭后向環(huán)空上返過程中，調節(jié)節(jié)流閥使立壓值保持不變，此時套壓值逐漸下降，當加重泥漿到達井口時，套壓降為零，重建起地層井眼壓力平衡，壓井結束。4.停泵后關閉節(jié)流閥觀察立壓、套壓值，此時立壓、套壓應該均為零。若立壓、套壓均為零時，可開井循環(huán)觀察兩周，正常后繼續(xù)鉆井作業(yè)。若立壓為零、套壓不為零時，可節(jié)流循環(huán)繼續(xù)觀察，循環(huán)直到套壓為零為止，再開井循環(huán)觀察。
