Core Sampling Technology and Its Application in the Unconsolidated Sediments Over Bedrock Marker in Suzhou,Anhui Province
摘要
Abstract
With societal advancement,drilling engineering faces increasingly stringent demands,driving the emergence of various innovative drilling methods.Due to variations in encountered strata,as well as the influence of development objectives and functional requirements,multiple drilling techniques have evolved,including positive circulation single-tube coring,double-tube coring,reverse circulation coring and wireline coring.Among these,wireline coring offers the advantages of low operational cost and high efficiency.Notably,the bottom jet drill bit wireline system is particularly suitable for complex formations such as soft-hard interbeds,gravel layers and sand layers,effectively mitigating issues like drill string sticking and borehole collapse caused by loose and fragmented strata.Compared to conventional methods,the bottom jet drill bit can shorten construction duration and improve core recovery rate.In recent years,this technology has been widely adopted in the drilling industry.关键词
