Abstract: this paper analyse the data such as mud-logging, wireline logging, acid fracturing completion testing, etc of well TP215X in TUOFU area, TAHE Oilfield, TALIMU Basin in Xinjiang province Recount the clasolite reservoir characteristics of lithology proterty, physical property, electrical property in Triassic system, Carboniferous System, Devonian system, Silurian system, the carbonatite reservoir characteristics of lithology proterty, physical property, electrical property in Ordovician system, and so the assembly of reservoir beds and cap formations of the above systems Construe the reservoir types, evaluate the developmental characteristics of the reservoir beds and the cap formations Final conclusion are: In this area, the reservoir space in Triassic -Silurian system are grain pores, the reservoirs in Triassic system are developmental ones, reservoirs in Carboniferous System are undevelopmental ones, the reservoirs in Devonian system, Silurian system are ever developmental ones, in Ordovician system the accumulate space are pores & cavities and fractures are undevelopmental There are four main assembly of reservoir beds and cap formations, the cap formations are all good This paper can provide detail real basic data for understanding the assembly of reservoir beds and cap formations in twell TP215X area, for more deep investigating the geologic condition of controlling oil, basic research, calculation of reserves in the area, and for making the next exploration and development plans
Key words: clasolite, carbonatite, characteristics,evaluate,reservoir, cap formations, assembly
