Oil and gas capital evaluation is a practical, comprehensive and highly theoretical research, is mainly composed of all oil and gas exploration in the French department. Geological evaluation of the basin is the oil and gas resource evaluation parameters of certain important step, is the most important step is statistics certainly important according to certain statistical parameters of basic and analogy analogy parameter, directly determine the reliability of the capital evaluation. Through the evaluation process for different basin types, different level of investigation under the premise of comprehensive analysis and comparative research methods, comprehensive understanding and control of important global accumulation regional big basin structure background, sedimentary basin evolution, basic petroleum geological condition, summarizes the different types of reservoir basin oil and gas accumulation discipline, evaluation of these the accumulation of oil and gas in the basin resources, and the potential to find out the situation, stop the sort, in order to extend with foreign oil companies on the global accumulation Nianye Nianye area basin oil and gas analysis of gap, enhance competitiveness, in order to actively counterattack, to obtain a greater share of oil and gas, and try to establish itself as soon as possible oil and gas production base. This paper is an important research in southwest Germany, petroleum geology of Poland basin and the characteristics of capital in Europe petroliferous area stop. German southwest Poland basin oil and gas geological research and the premise of capital evaluation is a department of Petroleum Prospecting Institute Project "in Europe and the Arctic region of petroleum geology and potential research" of the capital. The important is through the process of the following steps: 1 to complete the research on basin. The material collection and reorganization and the European oil and gas bearing area and basin information coherence, review, compile, basic geological materials in foreign petroleum geological characteristics of rectification, all know the European region. 2. Through the evaluation of the southwest Germany - Poland basin 1HS and USGS conditions, combined with collecting rectification materials, establish the basic database for early evaluation task. 3. On the geological characteristics of oil and gas in the basin research, including basin structure analysis and static features discussion. 4. System in petroliferous basin and reservoir research, contains oil and gas division and its static elements of description, description of static elements; and in oil and gas system study, divided into the basin into reservoir scale. 5. Capital evaluation and speculation, reservoir combinations as the basic evaluation unit for each reservoir combinations of crude oil, natural gas, condensate oil has been invented before the invention of the amount of capital capital amount and makes the evaluation and forecast. In the process of basin research, an important application of the following measures: 1. Through literature research, comprehensive analysis, put forward a set of domestic capital containing petroleum geology and evaluation methods; 2. In the course of the study of petroleum geology in the basin, the application of Arc GIS software to establish the database processing system and a comprehensive analysis of the material splicing results, and on this platform of comprehensive analysis and research; 3. Take the invention process method to collect materials have been invented as the basic oil, through the process of probability statistics ways to determine evaluation units of oil and gas amount of capital, make the evaluation results more useful. Through the above process of important research has obtained the following results: 1. Regional geological outline: southwest Germany, Poland basin was long strip spread to the strike of the NW to se, located in Poland, Germany, the land and the ocean and Danish ocean and basin in the North West to southwest direction, long 700km (11 degrees east longitude to 22. Between), north to southwest 325 km wide. 2. Basin evolution: the composition of the Polish basin in southwestern Germany began in the Late Carboniferous Early Permian, it is important to a developed on the basis of the foreland basin of Carboniferous reunion type L rift / thermal subsidence depression basin, is a negative inversion basin. Early / Late Permian accumulation of Aeolian sandstones and evaporites (red bottom systems), followed by the 1500 thick Permian in the upper part of the evaporites rocks and carbonate rocks (zechstein) 2500 thick alluvial and wind. The Triassic produced a new rift movement, until the continuous to late Triassic, constitute a series of independent north-south graben. In Late Triassic to Jurassic produced thermal subsidence, transgression incurred and shale are formed in the middle of the basin, the edge of a shallow sea and deltaic sandstones. This kind of type of accumulation always continuous to at the end of the Cretaceous (marine shale accumulation gradually growth), medium and late Jurassic has experienced a little deformation. 3. Basin static elements features: 1) hydrocarbon source rocks: basin have demonstrated the important source rocks and oil source rock separated upper Carboniferous system of coal seam and magnesium limestone series marine shale. 2) reservoir: the geographical composition of storage reservoir important formation in the lower Permian alluvial fan deposits and wind product deposits (oil and gas reservoir), Upper Permian algal dolomite, medium important including dolomite (high accuracy of oil and natural gas reservoir). 3) cover: red bottom cover layer and the important zechstein reservoir and the upper Carboniferous reservoir is zechstein evaporites (is an important rock salt and anhydrite). 4. Oil and gas system: basin has proven the two petroleum system for Upper Carboniferous Permian (!) oil gas system and Zexisitan - Zexisitan system, Triassic (!) oil and gas system; assumed two petroleum system of Mesozoic strata in the Mesozoic (? The lower Paleozoic Petroleum System) and an upper Paleozoic, Mesozoic (? Oil and gas system). 5. On the basis of the two oil and gas system has certainly can be divided into two reservoir combinations: Rotliegendes reservoir combination and zechstein reservoir combination. 6. Through to the Tibetan group source evaluation obtained: important prospecting potential of the basin is in have already established Permian red bottom system, magnesium limestone system reservoir combination, although reborn boundary strata in till today invent the most several oil and gas used, however in this set of strata mature source rock, reservoir, structural traps into hidden elements have been invented, is to match is a potential target. 目录: |
