%X Reservoir attributes change quickly in the Qiaokou deep gas reservoir in the Dongpu depression, so the reservoir assessment is difficult to be done. Using data of geology, well logging, and laboratory testing, this paper researches on different aspects of the reservoir, such as sediment microfacies, diagenesis, rock texture and so on. The sand body of channel in the middle sublacustrine fan has good porosity and is favorable reservoir. Secondary chemical erosion intergranular pores are the main pore type, the grain size of rock is small, the sorting is middle or bad, and dot\|line contact is the major form. The flaky and curved lamellar throat is major proportion, so the reservoir is low porosity and permeability. Due to chemical erosion and metasomatism, some formations have developed secondary pores, and favorable reservoirs can also be found in deep layers.
