Eastern Sag In Liaohe Depression South Of Igneous Research

At present, our researches toward the extension of oil and gas reservoirs are inevitablewith the development of oil-gas exploration, so the further study on the situation of geologicalfaults becomes particularly important, A large number of domestic and foreign research hasachieved a series of results Which shows that the main faults is the key control for geologicstructure，sedimentation and volatility，the effect on reservoir in basin as well as the ties withthe geological structure, and be the guidance of modern oil and gas exploration.Through this research, the distribution extent of igneous rocks of each layer especially inSha3section was clear. Study of igneous rocks in the plane along the main fault distribution,has certain inheritance and the performance for the period by strike-slip displacementcharacteristics; vertical multicycle characteristics, and the volcano eruption cycle division,summarizes the different cycle characteristics, combined with characteristics of theearthquake, the volcano rock of portrait.Igneous and volcanic rocks mentioned in this article are equivalent of igneous rocks:refers to the high-temperature melt formed in the deep crust or upper mantle, the invasiveunderground erupted to the surface condensation and the formation of rock. On the basis ofextensive literature research and basic data collection, collation, start from the solidfoundation of research, the applications targeted technical means, analysis of differenthistorical periods of volcanic activity patterns, basic petroleum geology structure, sedimentaryevolution of magmatic activity the impact; many ways to explore the control of majorvolcanic main controlling factors of hydrocarbon accumulation, summary of the the differentvolcanic oil and gas accumulation model, proposed structural styles conducive to hydrocarbonaccumulation. This paper summarizes the three sections of sand, sand for some, developmentcharacteristics of of Dongying Formation volcanic rocks and intrusive rocks and distributionlaw. Integrated use of the physical properties of the oil and gas shows and oil testing data,igneous rocks, facies type classification, recognition and prediction of system analysisigneous forming rules for the next oil and gas exploration and specified direction.The igneous rock analysis plays an important role on the eastern depression of theformation of igneous reservoirs, but lack sufficient knowledge of the quality igneous rocksfacies. The igneous rocks on the the Liaohe Depression south section of the facies andlithologic features in-depth study, the results show that the the Liaohe Depression qualityigneous reservoir is mainly present in the three sections of the Shahejie. Cccording to the actual conditions of the study area, combing with theory of igneous research at home andabroad, igneous rocks was further evaluated in the region.
