Exploration of Optimized Fast Drilling Technology for Horizontal Well in Daniudi Gas Field

Abstract:

Daniudi is an oil and gas reservoir with low pressure, low permeability and low abundance, whether the optimized fast drilling is in put in use become the main factors restricting the development of horizontal wells. Through the statistical analysis on the well structure, BHA, bit selection and the drilling mud system, an optimized fast drilling technology is summarized, which is suitable for Daniudi gas field and can substantially improve the drilling speed and shorten the drilling cycle.

Key words:oil and gas reservoir; horizontal well; well structure; mechanical efficiency; mud system; optimized fast drilling
