Abstract: Taking buried hill reservoirs in Lunnan，Tarim area as an example，the relationship between such geologic characteristics as lithology，physical property，structure，dissolution of carbonate buried hill reservoirs and acid
fracturing deliverability are comprehensively analyzed.The research indicates that firstly，the rock types are the fundamental factors to control oil and gas production，karst types and their development degree are the main factors.Yijianfang Formation and Yishan Formation which are mainly shoal sedimentation，various limestone deveolps，and primary pores which are in favor of karstification develop，so the reservoirs with good acid fracturing response are in these formation，secondly，reservoir types and fracture development degrees are the key to control oil and gas production.The influence of reservoir types on acid fracturing deliverability are cavity，fracture-pore and fracture orderly，thirdly，different lithostratigraphic distribution and geomorphic karst unit directly influence longitudinal distribution of high production formations.A lot field experiment of acid fracturing indicates that high production wells locate in buried hill peak and depth range changes a lot，the distribution depth is different in different areas，but mostly in 200m，especially in 100m.The dominance of buried hill vertical depth on reservoir quality is still under the control of rock types and longitudinal distribution of karst phase belt.
