杜84 - 平45 井辽河油田SAGD 试验区的一口水平井,是辽河油田精度要求最高的一口中半径水平井,造斜段地层疏松,水平段较长,地层有一定不确定性。通过精心设计钻具结构和钻井参数,采取得当轨迹控制技术,以及良好合理的钻井液体系和得力的井下安全措施,完全满足了甲方要求,全井安全无事故。该井是辽河油田所完成水平井中,水平段最长、周期最短的一口中半径水平井。

Du84 - ping45 well is one horizontal well in Liaohe oil

field SAGD experiment area , and is also the best accuracy

JUL Y 2004 FAUL T2BLOCK OIL & GAS FIELD Vol. 11 No. 1

request middle radius horizontal well. Build stage strata is

loosen , horizontal segment is longer. There is some

uncertainty in the geologic strata. Through designed the

construction of drilling pipe and drilling parameter carefully ,

and adopted properly technique of controlling trace ,and the

better reasonable system of drilling fluid , as well as the

satisfactory downhole safe measure , so those makd the oil

company satisfy with the well and there is no ang accidmt all

throogh the per iod. the weil is the best accuracy ,the longest

horizontal segment and the shortest period one of all

completed horizontal wells in Liaohe oilfield.
