Abstract
There is danger of wellbore touch in the process of cluster well drilling in intensive wellhead. Relative position of wellsite and structure was studied and correspondence relationship was analyzed. The anti-touch problem was solved by scien-tifically arranging wellhead and drilling target, optimizing borehole profile and track, wholly considering drilling construction scheme. There are totally 76 wellheads in the artificial well site in district 1 of Chenghai Oilfield. As many as 51 wells were planned to drill. Among them, there are 21 extended-reach wells which are all located in a sector of 30°. An integral drilling scheme was made before spud in. At present, the scheme is being implemented. Filed results show that all the wells are con-ducted successfully except that a well was touched with near borehole because of measuring instrument error.关键词
