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.

K-Ar dating of authigenic illite and its applications to study of oil-gas charging histories of typical sandstone reservoirs, Tarim basin, Northwest China;

Present situation and prospect of igneous reservoir exploration in Liaohe basin;

This paper presents the study of the igneous rock lithofacies and seismic recognition marks,the discussion of the relations between igneous rocks and oil-gas reservoirs,pointing out the favorable zones of igneous reservoirs.

Volcanic sedimentary sequence study and stereo exploration of igneous reservoir are becoming major features.

A series of seismic prediction technology for igneous hydrocarbon reservoir exploration in the Eastern Sag of Liaohe Basin is summarized on the basis of characteristic analysis, production practice, and prediction method study.
