| 摘 要： | 埕子口2井上部地层易造浆，剥蚀掉块严重，泥岩地层易缩径。下部地层层理、裂缝发育，易出现井漏、井喷、井塌和卡钻等复杂事故，为此三开井段选用了可循环泡沫钻井液。现场应用表明，可循环泡沫钻井液防塌、抗污染能力、携岩能力强，堵漏和保护油气层效果好，满足了埕子口区块优快钻井的要求。

| Abstract: | The upper formations in Chengzikou 2 Well tend to make mud, slough and undergauge; and the lower formations with developed stratifications and fractures contribute to such troubles as lost circulation, blowout, sloughing and stuck pipes. Therefore, the foam mud was employed in the production section for above reasons. Its applications show that the foam mud holds helps for protecting sloughing, resisting contaminations, carrying out cuttings, plugging and protecting reservoirs; thus, it can be applied for efficiency drilling in the Chengzikou block. |
