Gudao Oilfield fault seal ability research and development of oil and gas application

摘要

In Gudao Oilfield Southwest margin area, fault seal ability to determined under Guantao formation study reservoirs distribution has a very important significance. Through the research fault two plates of lithology relation, mudstone daub analysis, fault zone fillings argillaceous content analysis of the gender influence factors of study area, main fault sealing ability analysis results show that upper Guantao formation and under Guantao formation7, 8 sand formation fault seal ability is good, beneficial to the forming reservoirs; Under Guantao formation8 sand formation the following fault seal ability is bad, and can be used for oil and gas migration channels.
