Analyzed are the main causes of perforated string sticking accident in the process of perforation completion by using 89 mm composite perforator in igneous reservoir in Xiaolongwan area,Liaohe oilfield.

the influence of standard means,structure parameters and log of SOM network on cluster results,which shows that good results can be achieved for lithology recognition on logging data of igneous reservoir by using normal standard method,selecting proper structure parameters and log, and taking the cluster results as the basis of classification.

The basis of volcanic rock reservoir study and pool description is the recognition of volcanic rock well logging.

In recent years,as the breaking through progress of the exploration and exploitation for volcanic rock reservoirs,the reservoirs have become new targets for exploration and exploitation.

Based on synthetic study of core,mud logging,conventional logging and imaging well logging data,the volcanic rock reservoir types in Xushen gas field are researched.

Study on control factors for forming volcanic reservoir in Xingcheng development area of Xushen Gas Field;

Research on lithology and facies of volcanic reservoirs in Qingshen gas field of north Songliao basion;

Investigation on characteristics of volcanic reservoir in Zao 35 Block;

In order to identify microfacies of volcanics in Xujiaweizi area, volcanic reservoirs were studied in terms of micro structure, reservoir type and parameters based on data of coring, gas testing and logging.
