Oil And Gas Pathway System Framework，migration And Accumulation Rules In Hailar Basin Beer Sags

This paper mainly studies on the Baer depression in Haita basin pathway systemframework and its migration and accumulation, oil and gas transporting system frameworkhas three main types: sand body, unconformity surface and fault. Sand body mainly throughits porosity and permeability, sand thickness of sand bodies, horizontal length, formationpressure and factors on the material analysis, divides the target zone of different transportingability of sand body. For the integration of research, we first use the GRNN method to removethe sonic time difference correlation factors, so that it only buried by a deep impact, and thenthrough the acoustic changes analysis of unconformity surface, analyzes the reasons, finallythrough unconformity thickness to evaluation of the Baer depression unconformitytransporting ability, Baer sag regional development with many faults, such as the Sudeerteand Huo Duo Moore, for different regions within the fault effect on hydrocarbon migration,we adopted formula to qualitative representations, by studying the fault activity cycle and theprofile of the position of the judgment of fault is how to influence the oil and gas migration istrap or become migration channel. Nitrogen is the migration direction of oil and gas path onthe favorable evidence, based on the Baer depression around the index research plus prior toits passage system framework of evaluation, which can be depicted Baer sag gastransportation distribution.In this paper, we take the more mature basin simulation software PetroMod to calculate,at the same time, thickness of strata and basin analysis the parameter of hydrocarbongeneration and expulsion history of simulation, through the two migration calculation, namelytwo migration direction of oil and gas. Finally, we simulate the results show, in a bay indivergent migration from source rocks, the center spread to the surrounding, and Bei Xiyuanrock due to sand transporting capacity to the southeast side of migration, but meet theSudeerte and Huo Duo Moir tomography and accumulation, and Baer sag in the east also hasa reservoir there.
