Raoyang Sag Microelement Distribution Regularity,Occurrence Condition And Reservoirs Instructions Significance In Deep Soil

Oil and gas geochemistry is an exploration technique, and geochemicalexploration has made a positive contribution to the Chinese oil and gas exploration inthe20th century and will continue to play a more important role in the future of the oiland gas explorati. Itself will get more development. The reason is that the oil and gasexploration has a direct, fast, low into the prominent characteristic or technologicaladvantage.In this paper, the multi-objective data of the geochemical regional survey1:250,000plain area of Hebei Province, the distribution laws of trace elements in areasof deep soil Raoyang depression are discussed. By collecting information and deepsoil samples, we can analyse the element distribution rule in this area through the X-raydiffraction analysis of soil samples,we can discuss the form of occurrence in soilelement fluorine. Through the analysis of the key zone of trace elements distributionand the space of the oil and gas distribution corresponding relation,we can explore theindication of oil and gas in enrichment region trace types and characteristics ofabnormal exhibition cloth distribution characteristics, analyse the the factorscontrolling the change of the trace elements in soil in the oil and gas display areas., inorder to service for oil and gas exploration, And the deep soil using the trace elementsin the target area for oil and gas exploration, the choice of the research work.1.Trace elements of the regional distribution characteristics can reflect the tectonicunits and concealed structures distribution.Deep soil samples element content distribution and concealed structures havehigher space between the corresponding relation.Elements are low value distribution insag area,while elements are high concentration distribution situation in raised area.Concealed fault is the main reason which leads to this distribution.This is because thatthe area between the sag area and the raised area is fault contact zone.The fault is themain channel through which the trace elements up. As the above mentioned, theelement distribution presents this form.2.In the tectonic units sag area, the upper part of the reservoirs that trace elementsfor high value area, the area for low value over oil-gas reservoirs, and has a good spatial corresponding relation.3.Oil and gas display area above the content of trace elements of high and lowdistribution is mainly controlled by the joints and crack development degree.Joints growth area above the oil and gas are high and trace element contentdistribution situation (no.4profile), joint development of oil and gas in not above alow value distribution situation trace elements (3profile), if oil and gas is located intransition joints growth area, the oil and gas distribution above the trace elements inalso shows the transition state distribution (2profile)4.The distribution of trace elements in form in the fracture of a closer relationship,high value area of extended upward direction correspond to fracture5.As the research about the elements form of occurrence in the Oil and gas displayarea shows,the main elements for convex area of ferric-manganese oxidation state,residues of the state high content distribution area, and oil and gas display area for eachelement to the minimum content distribution state residue. Ion state, water soluble statein different tectonic areas such as content a little change. And various forms of contentdistribution of elements in the total distribution law, similar to that oil and gas areas forhigh value above elements distribution area (no.4profile), each element of thedifferent existence form has also been high value distribution for the Lord; Oil and gasdisplay area element for low concentration distribution, each element form also muchfor low value distribution.
