In the Eogene and Neogene, Qaidam Basin experienced the multiphase tectonic movement; the paleoclimate evolved from warm-humid to arid; the water in the basin was gradually salinized; the depocenter migrated from west to east. The master factors and developmental characters of lithologic hydrocarbon reservoirs have their own particularity. Taking the fine exploration zones of the southwest hydrocarbon-rich depression in Qaidam as the key point, with the analysis of source-rock distribution, sedimentary evolution and sedimentary system distribution, the author proposes that the density difference increases after the fluvial water enters, then clam and bar sand bodies are formed easily due to density flow. Highstand system tract and transgressive system tract below the maximum flooding surface are the main exploration areas of lithologic reservoir.

柴达木盆地古近纪－新近纪经历了多期构造运动，古气候由温湿向干旱演变、湖盆逐渐咸化、沉积中心由西向东迁移的演化过程，地层岩性油气藏的主控因素和发育特征有其特殊规律，以柴达木盆地柴西南富油气凹陷精细勘探区带为重点，通过分析烃源岩展布、沉积演化和主要沉积体系展布，提出咸化湖盆在河流入湖后因密度差较大，易形成密度流等成因的各类滩坝砂体，最大湖泛面之下的高位体系域、湖侵体系域是地层岩性油气藏的主要勘探领域。

The fan delta, sand beach, sand bars and turbidite fan in the TST of SⅡ and SⅢ sequences are the most favorable exploration targets because of favorable source - reservoir - seal assemblages. Since the high - stand system tract in SⅡ sequence has good source - reservoir assemblage and is covered by the regional seal of SⅢ sequence, the hydrocarbon accumulation in this area is controlled by the local seal rock. The HST of SⅡ sequence becomes the second favorable exploration target zone. Because the scales of the sand bodies of alluvial fan and braided river in low - stand system tract of SⅡ and SⅢ sequences are limited, the formation of a large hydrocarbon accumulation is difficult.

良好的生储盖配置使SⅡ层序、SⅢ层序水进体系域的扇三角洲、滩坝及浊积扇砂体成为本区最佳勘探目标层。SⅡ层序高位体系域生储条件配置好，又有SⅢ层序区域盖层的整体封盖，油气聚集受局部盖层直接控制，可成为较有利的勘探目的层。SⅡ层序、SⅢ层序低位体系域的冲积扇、辫状河砂体体积规模较小，难以形成大油气藏。

To dec.2002 were analysed by means of wounding tract and fracture.results during 24 cases of gunshot wound, wounds of 20 cases healed without event after primary debridment and sewing wounds,3 cases healed and l case infected in 4 cases of primary debridment without suture,and 4 cases of primary internal fixed fracture had no osteomyelitis.the injury of soft tissue and contamination of wound track were serious in explosion wound than in gunshot wound,10 cases healed without event and 4 cased infected in l4 cases of primary closed explosion wounds,and 2 cases of primary inernal fixed fracture had no osteomyelitis.conclusion it is suggested that the management of firearm wound in cold and dry region may be delayed moderately in time of debridement.the firearm wound may be treated by internal fixation of fracture and primary closing of tract after early debridment when the soft tissue injury was light in peacetime, which decreased the infection,disability and promoted rehabilitation of patients.

结果 24例枪伤中，20例一期缝合伤口，均一期愈合，另外4例只清创未一期缝合的伤口，3例愈合，1例感染；4例骨折内固定均愈合良好，无骨髓炎发生。16例炸伤病人局部软组织损伤及污染比枪弹伤重，14例一期缝合伤口中，10例一期愈合，4例感染，骨折内固定2例，均愈合良好，无骨髓炎发生。结论寒冷干燥地区火器伤早期伤道清创时限可适当延长，在平时火器伤的救治中，对软组织条件较好的创面，早期清创后可一期闭合伤口和骨折内固定，这样可减少感染和伤残，促进康复。寒冷干燥地区；火器伤；早期救治
