摘要
Sacha-373H是川庆钻探厄瓜多尔分公司在厄瓜多尔Sacha区块项目管理服务的第一口采用威德福方位伽马及成像技术(HAGR)的水平井,该井通过采用HAGR技术,结合综合录井和气测录井技术对着陆和水平段进行了地质导向施工,并成功完成了该井薄油层水平段的钻井施工,因此,总结该井在着陆和水平段地质导向成功实施的经验,改进施工过程中的不足之处,对于今后更优质地在Sacha区块实施水平井钻井项目管理服务,最大限度地穿越储集层,提高油层钻遇率具有重要意义。
Well Sacha-373H drilled by CCDC Ecuador Branch is the first horizontal well Weatherford’s HAGR(azimuth gamma and imaging technology)been applied at Sacha block.HAGR together with comprehensive logging and gas logging has been used in geosteering drilling of landing and horizontal section to successfully drill through the horizontal interval in the thin oil reservoir.To draw lessons and experiences from that practice is significant for higher quality horizontal drilling project management and maximum drilling through the reservoirs at Block Sacha in the future.
