Parameter well allocation and execution during initial stage of shale gas exploration can use slim hole drilling technology to reduce coast. Taking the drilling of parameter well Changye No.1 well in Taiyangshan anticline, Changde area, northwestern Hunan as an example, introduced the key components of shale gas slim hole drilling technology, including drilling equipment selection and allo-cation, drilling tool structure, drilling parameters selection and optimization, mud system selection and performance maintenance, wire-line coring technology, gas content and site desorption test, common accidents prevention and processing, well completion technology etc. The successful application of slim hole drilling technology has shown:it not only can satisfy shale gas exploration initial stage drill-ing purpose, also shorten drilling period, lower down drilling cost and acquire good economic benefit.
