摘要
研究疏松及破碎地层钻井取心技术的主要目的是解决松散、破碎地层的取心问题,由于该种地层岩心的不成形,致使钻井取心收获率低,不能满足地质勘探开发的需要。胜利油田钻井院通过几年的刻苦攻关,研制成功了相应的钻井取心工具与取心技术,经过室内与现场试验证明,该技术可行,并初步见到良好效果。
The main purpose of researching drilling coring technology for unconsolidated and broken formations is to solve the coring complex problems associated with these formations. For the core shape is very poor in these formations,the average core recovery is usually very low,and it can not satisfy the requirement of petroleum exploration & development. The Shengli Oilfield Drilling Technology Research Institute has developed the corresponding coring tool and coring technique for these formations successfully. It has been proven to be feasible by laboratory tests and field trials,and the good result has been gained.
