[Abstract]:Paleogeographic evolution of sedimentation and is a series of basin analysis under different sedimentary environment of sediment characteristics and distribution, and then analyzes the material foundation and conditions for oil and gas and solid mineral formation and distribution of oil and gas and solid mineral resource potential, and further guide the exploration work. The title of this paper from "the Qiangtang basin uplift area, Hubei Lake - Venus oil-gas resources investigation project of" key > Qiangtang block the investigation and evaluation of sub project, Middle Jurassic Buqu Formation in selected sub project in Hubei, Hubei smart long area as the research object, this paper uses the modern theory of sedimentology. The study area Buqu group carried out a detailed rock structure, sedimentary structure, sedimentary facies and lithofacies palaeogeography study, and on the basis of the Middle Jurassic Buqu Formation oil source, reservoir, favorable area of oil-gas are briefly Analysis of the North Qiangtang basin. The Hoh Xil Jinsha River suture zone, the southern boundary of the Bangong Lake Nu River suture zone, the Qiangtang basin has been divided into the central uplift belt of South, north two depression. This study area belongs to the southern Qiangtang Basin in the west part, Tibet Shuanghu county within the scope of the lung, Hubei area, near the East Hubei Sima Amdo county area, geodetic coordinates of longitude 88 degrees 30 degrees 30 '' ~90 30 ', north latitude 32 degrees ~33 degrees. According to the measured field profile, profile, route tracking survey and drilling data, combining with the comprehensive analysis of previous research results, made the following.1. Hubei Hubei long Nepal - Smart formation into overall east-west extension, with north-south zone feature in the tendency. According to the formation of rock assemblages of fossils characteristics, the strata in the study area from the north to the South can be divided into three stratigraphic regions, namely north of the pedicle Let bi - wrong Chalangla stratigraphicdivision, central biluocuo - ang Dahl fault Dazhuoma stratigraphic regions, south of Sodom - color Wow - Zhaqu stratigraphicdivision. Tugendhat Bi wrong - Chalangla stratigraphic division is mainly on the three Triassic tumengela group and Cenozoic strata; biluocuo - ang Dahl fault Dazhuoma stratigraphic area by the development of Buqu oil-bearing dolomite, limestone particles and a small amount of salt rock, brown and purple sandstone, silty mudstone and other characteristics; - Wow - Zhaqu Duoma color development stratigraphic division Buqu dark micro micrite shale with minor study area in.2. the Middle Jurassic buquformation rock types mainly in carbonate rocks, clastic rocks in the study area is relatively small. Only the East Qu BA from Dazhuoma to the area found in sandstone, siltstone, mudstone and Duoma - color Wow - Zhaqu formation District Ruiqia is curved section, curved profile stamp run found the mud rock carbon. Acid in salt rock is mainly limestone and dolomite and limestone area distribution, mainly for a variety of grain limestone and micrite dolomite; observed in algal laminated dolomite and crystalline dolomite; some areas showed a few gypsum.3. through sets of five aspects of a comprehensive study on the main profile Buqu, combined with analysis of dolomite and limestone in the top and bottom temperature of fluid inclusions and carbon oxygen isotope data, study of sedimentary zone facies can be divided into: tidal flat facies (including tidal shoal facies), lagoon facies, continental shelf facies.4. in a single section based on the analysis of sedimentary facies, with dozens of routes tracking profile survey and Buqu group (Xia Lizu), under (quse Sewa) special rocks (oil shale, salt rock) distribution and paleogeographic inheritance analysis, Hubei, Hubei developed long - Middle Jurassic Buqu Sima period lithofacies to Daniel. Research is put forward for the first time Area can be divided into: uplift zone, tidal flat facies, lagoon facies, shallow subtidal facies and shelf facies of 5 phase with.5. based on the study of lithofacies paleogeography, combining with the related data and analysis results of Hubei, Hubei long smart oil reservoir area. Prospective areas of favorable oil and gas are briefly analyzed. That source rocks with ancient reservoir mainly distributed in lagoon facies, tidal flat reservoirs mainly distribute in the lagoon and surrounding tidal shoal facies, favorable oil and gas exploration area as the study area in the eastern part of Hubei should be smart north area.
