The result of the study showed that the erosion intensity of Qianjiang Depression could be divided into three districts: the strong erosion district in the Northeast, the steady erosion district in the Middle and the slope erosion district in the Southwest Key Words: Qianjiang Depression; Formation Erosion; Erosion Thickness Restoration; Calculation Method Identification of Subtle - trap Reservoirs in Continental Petroliferous Basins by LI Ping- ping P. 19 Abstract: The classification of subtle- trap reservoirs was summarized and the basic theories of continental sequence stratigraphy were introduced. The close relationship between slope- break zone and subtle- trap reservoirs was analyzed and so was the identifying train of thought of subtle- trap reservoirs in continental petroliferous basins brought forward s paper. Petroleum- exploitation proved that the sand bodies of lowstand, which were related to slope- break zone were good subtle- trap reservoir chambers Key words: Subtle- trap Reservoirs; Continental Sequence Stratigraphy; Slope- break Zone; Earthquake Study the Submerged Features of High Water- bearing Reservoir at Lower Shaer Segment of East Wen 2 by ZHANG Ge, et al P 21 Abstract: The data of trap core analysis at the early, middle and late periods of reservoir exploitation was used to deveh op dynamic data. The submerged features of oil- bearing formation at Lower Shaer Segment of ast Wen 25 and the res ervoir changes were studied. The results of the study showed that the submergence of oil reservoir has made permeation of storage formation hole mre obvious, which mainly minimized the effective oles that could determine the flow of the res ervoir, thus reducing the oil driving efficiency and shortening the oil production period. These were the reasons that ex slained why this reservoir had a large pool of oil but the production was not increasing obviously Key Words: Reservoir Exploitation; Reservoir Structure; Submerged Feature; Water-driving Eificiency The Method for the Data Processing of Short-term Well- testing and Its Application by HAN Feng-rui, et al P 23 Abstract: Short-term well-testing could shorten the testing time, which would relieve the contradiction between well testing and oil production to a certain extent. The methods for the data processing of short- term well-testing were discussed in the paper. Some software suitable for explaining the data processing of short- term well- testing was dever oped and the application of these methods was illustrated with examples from the oilfields Key words: Well Testing Interpretation; Afterflow Quantity; Data Processing The Application of Grey Clustering in Submerged Layer Logging Interpretation by LU Yan, et al P 26 Abstract: The method for identifying submerged layer with grey clustering was brought forward in this article. This meth od was simple, convenient and easy to calculate, the level of submerged oil layer could be identified with the logging curves. The result got from the data processing of the 15 wells in Shengli Oilfield proved that this method was feasible and the logging coincidence rate was 81.8 in accordance Key Words: Submerged Degree of Oil Reservoir; Qualitative Evaluating Methpd Grey Clustering A Method to Analyze Low-resistance Reservoir of Complex Fault- block Oil Deposit by LI Di- shu, et al P 28 Abstract: Combined with the logging at Wendong fault-block oil deposit in Wenliu Oilfield, the method for evaluating the low- resistance reservoir of complex fault- block oil deposit was discussed, and so a successful method used in Wendong fault- block was introduced in this article Key Words: Fault- block Oil Deposit resistance Rate; Logging Analysis; Moveable Water Saturation Discussion on the Explanation Model of Water-bearing Saturation in Argillaceous Sandstone Reservoir by ZHANG Xian-ping, et al P 30 Abstract: Based on the data collected from the rock testing and feature analysis of the argillaceous sandstone reservoir at the Middle shasan Segment of Xia 52 Block in Linna Oilfield, the water- bearing saturation in this district was calculat ed with improved Archie equation, Waxman-Smiths Formula, Double- Water Method and I-Sw Regression Method Four water- bearing saturation mdels were set up. Contrastive analysis was carried out to test the result of explanation which showed that the improved Archie equation had a smaller result of explanation, Waxman- Smiths Formula had a larger result of explanation, and the other two metods had moderate result of explanation Key Words: Argillaceous Sandstone Reservoir; Water-bearing Saturation; Archie equation Finite Analysis on the Extrusive Intensity of Casing Pipe under Non- symmetrical Load 201994-2007ChinaAcademicJOurnalElectronicPublishingHouse.aLlrightsreservedhttp:/www.cnki.netKey words: Jiyang Depression ; Paleozoic Buried Hills ; Tilt Block Study the Erosion Thickness Restoration of Qianjiang Formation in Qianjiang Depression by WANGBin ,LIU Bao - jun P. 16 Abstract : By combining the method of acoustic time difference with seismic profile in sequence stratigraphic framework , the erosion thickness restoration of Qianjiang formation in Qianjiang Depression could be restored.
