Title: NEW CORING TECHNOLOGY FOR UNCONSOLIDATED AND BROKEN FORMATION
Abstract: 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.
