In recent years, large scale gas reservoirs have been found in deep volcanic layer of Songliao basin. The volcanic gas reservoir is characterized as extremely complex geological structure, several volcanic bodies reciprocally superposing in different periods, sharp lateral variations of lithology and lithofacies, various thickness, serious anisotropy, poor continuity, and poor contrast property. There is no successful experience about development of volcanic gas reservoir as a worldwide technological problem. The factor controlling gas productivity during process development of volcanic gas reservoir is a puzzled question. According to feature of the volcanic reservoir mentioned above, we interpreted lithologies, lithofacies, physical property of volcanic reservoir, degree of fracture development, pressure-sensitivity of reservoir, drilled well types as well as reservoir pollution, then got the main factor controlling gas productivity. This result will provide some guides for evaluating the gas productivity of volcanic reservoir and determined the schedule for development of gas volcanic reservoir.
Key words： Volcanic rock; Gas reservoir; Productivity; Controlling factor.
