【摘要】:焦石壩一期產(chǎn)建區(qū)水平井地質(zhì)導(dǎo)向主要采用常規(guī)LWD技術(shù),隨著開(kāi)發(fā)南移,地質(zhì)條件更加復(fù)雜,常規(guī)LWD地質(zhì)導(dǎo)向鉆井技術(shù)由于測(cè)量盲區(qū)長(zhǎng)、測(cè)量數(shù)據(jù)種類(lèi)有限等原因,無(wú)法實(shí)現(xiàn)真正意義上的地質(zhì)導(dǎo)向鉆井。pathfinder近鉆頭地質(zhì)導(dǎo)向鉆井技術(shù)與常規(guī)LWD技術(shù)相比,能將測(cè)量盲區(qū)從13~17m縮短至1m以內(nèi),方便及時(shí)調(diào)整井眼軌跡;能讓動(dòng)態(tài)數(shù)據(jù)誤差≤5%,可精確判斷地層,以及定量和定性判斷優(yōu)質(zhì)小層;能實(shí)時(shí)測(cè)得11項(xiàng)參數(shù),以輔助判斷工具在井筒中的工作狀態(tài)。涪陵工區(qū)13口井的應(yīng)用表明,該項(xiàng)技術(shù)的應(yīng)用,有效突破了焦石壩邊緣地區(qū)斷裂發(fā)育、地層產(chǎn)狀陡且變化快等復(fù)雜的地質(zhì)條件給水平井地質(zhì)導(dǎo)向帶來(lái)的難點(diǎn)。
[Abstract]:The geological guidance of horizontal wells in Jiaoshiba Phase I production area is mainly based on conventional LWD technology. With the development moving southward, the geological conditions are more complicated. The conventional LWD geological guidance drilling technology is due to the long blind area of measurement and the limited types of survey data, etc. Compared with the conventional LWD technology, the real geological guided drilling. Pathfinder near bit drilling technology can shorten the measurement blind area from 13 ~ 17 m to less than 1 m, which is convenient to adjust the hole trajectory in time. It can make dynamic data error 鈮,
