Quantitative Study On Character Of Carpet Type Storage Layer In Meshwork-carpet Type Oil And Gas Pool-forming System

As the junction that connect meshwork layer of oil source passage with meshwork layer of oil and gas accumulation in meshwork-carpet type oil and gas pool-forming system, storage layer storage hydrocarbon from meshwork layer of oil source passage temporarily,carry on hydrocarbon accumulation of the upper layer. Directed by the fundamental theory of geology of petroleum and fluid mechanics in porous medium, based on hydrocarbon secondary migration theory, from energetics view, apply persistence of energy and fluid mechanics in porous medium and migration dynamic equilibrium, associate mathematical with model physical model, integrate geomathematics means and computer measure to proceed factor analysis on basic research of storage layer and control geologic condition, confirm dominant effect factor of storage layer, course semiquantitative or quantitative analysis to bearer hydrocarbon in storage layer, research distribution of hydrocarbon surplus pressure and surplus pressure modulus after reaching storage layer, derivate migration and accumulation dynamics equation in storage layer, through verification in practical region of interest, approve the exactitude of the mode. Meanwhile, study fault activity, analyse impact of matching of storage layer and fault transforming system to hydrocarbon accumulation. While storage layer conductivity and fault activity are well, reservoir form in meshwork layer of oil and gas accumulation.
