Abstract
A ccording to the analysis of the geo log ica l pro file and the dr illing da ta, the distribution character istics of Jurass ic source rock, Q ianhonggouzi area o f A ljinshan in Ca ix ,i has been revea led. The Jurassic form ation has the resource po tentia.l The Jurassic Dame igou form a tion can be regarded as the o il source layer. The upper layer has no good source- rese rvo irseal assemb lage. The unconven tiona l reservo irs ex ists in the low er layer and have good reservo ir cond itions. The low er Jurassic layer has good source rocks and the upper layer has good sea l conditions. They can fo rm autog enetic and se lf - sto ring assemb lage re lationships. The lowerM iddle Jurassic is the prog radational fan - delta facies, w ith coursing upwa rds, wh ich has the exce llent source- reservo ir- seal assem blag e ve rtica lly.
