摘要
焦石工区韩家店组、小河坝组、龙马溪组上段中上部属于深海陆棚沉积,岩性以灰色泥岩为主,录井工作难度较大。通过运用微钻时录井法、气测录井卡层法、特殊岩性识别法等3种常规录井方法,发现其在焦石坝水平井地质导向、取心卡层等方面发挥着重要作用,特别是在B井取心卡层、H井地质导向、X平台卡取中完井深等方面都取得了较好效果。
Hanjiadian Formation, Xiaoheba Formation and middle--upper part of upper Longmaxi Formation in Jiaoshi work zone belong to deep--sea shelf deposit with grey mudstone as the main component. Three conventional logging methods including micro--drilling time logging, gas logging--based layer division and special lithology-- based identification have played an important role in horizontal well geosteering and coring for layer division, achieving better application effects especially in B Well coring for layer division, H Well geosteering and X Platform well completion depth division.
