Abstract

In view of the ordos basin Chang7 shale oil "pressure-stuffy-mining" shown in the process of "horizontal length is uneven, the drilling time after large volume fracturing, and drainage system strength is different", by the analysis of indoor experiments, numerical simulation and mine production data, comprehensive study regional geological characteristics and investment cost, optimize the length of the volume fracturing in ordos basin Chang7 shale oil reservoir efficient development technology policy. studies have shown: (1) Based on the relationship between geological characteristics of the study area and horizontal section length and production and single well investment, the reasonable horizontal section length in this area should be controlled at about 1500m; (2) The seepage process is mainly oil and water displacement in small pores for oil displacement, and the formation pressure time is 30-45 days; (3) Horizontal well return strength is large, and the oil time is relatively fast, but with the increase of the return strength, the horizontal well sand is serious, and the artificial crack diversion capacity is reduced; (4) Establishes the single well based reservoir classification structure of shale oil, based on the change characteristics of flow filling ratio in the return stage. The research results will effectively guide the development and production of shale oil reservoir in the combined area of Ordos Basin.
