3、g Jiachang-Longchang area is located in the edge zone of Luzhou palaeohigh,there are plenty of petroleum and natural gas resources, Changba, Maliuchang reservoir, etc. have gas in Jia Lingjiang formation. T1j51~T2l11 for

4、mation in the study area are semi-confined~restricted sea platform facies,pinhole development,reservoir heterogeneity,diagenesis complicated, the control factor and the distribution of beneficial reservoir are complicatd

5、 and these will affect the exploration outcome..According to the well testing report, T1j51 formation of Ling1 well produced 3.34×104m3/d gas in the well testing in 2008, and this demonstrated its excellent explorat

6、ion potential. In this case, in order to guide further exploration and development.this paper studies firstly reservoir characteristics,the distribution of reservoir parameters and reservoir distribution, etc. and evalua

7、tes the reservoir further on this basis. Analysing the study area’s various datas belonged to T1j51~T2l11 formation， such as the data of drilling.sample logging.well logging.testing and laboratory test， adopting the met

8、hods combined with the traditional fundamental geology and mathematical geology, summarizing previous research results of this area ，this paper studies and evaluates the reservoir of T1j51~T2l11 formation. According to

9、 previous research of the sedimentary facies of Shunan region,T1j51~T2l11 formation in the study atea are roughly divided into sub-limit sets flat subfacies, semi-restricted lagoon subfacies and tidal flat subfacies.Stud

10、ying the petrology characteristics of reservoir rocks,diagenesis,reservoir space types,pore structure and reservoir characteristics,this paper have this conclusion： first， rock types of T1j51~T2l11 are complexed，and the

11、most are microcrystal~calcsparite limestone and dolomite.reservoir space type is complicated,and the most are intergranular dissolution pores and intragranular dissolution pores;second，the pore throat types of T1j51 main

12、ly is medium-narrow.and the pore throat types of T2l11 mainly is large-medium;third， the sedimentary environment and diagenesis affect the reservoir’s property.Among them,the contribution of dissolution was positive ,whi
