Abstract

In order to improve the drilling efficiency of two oil and gas geological survey wells "Jitaodi 1" and "Ji Bai Di 1" in Baicheng area of Jilin Province, wireline coring technique was applied in overburden drilling. Based on the lithological characteristics of the drilled strata, combined with the technological characteristics of core extraction by lifting the drill pipe and wireline core extraction, by designing the bit, drilling flushing fluid and by improving drilling procedure parameters, drilling tool nozzle flow channel, the wireline coring drilling method has been successfully applied in drilling overburden strata(about 1 100 m thick). Compare with the traditional coring method of lifting single/double tube, drilling efficiency and core recovery of wireline coring increased by more than two times, the lifting drill pipe cycle raised to more than 2 days, the labor intensity is greatly reduced, the construction period is saved by nearly 30 days. This paper introduces in detail the improved method and construction experience of wireline coring technique in overburden drilling in Baicheng area, it has certain reference significance for the popularization and application of wireline coring technique in overburden drilling in the future.
