Southern Changyuan Oilfield Heidimiao Oil And Gas Reservoir Evaluation

Southern Changyuan Heidimiao oil gas reservoirs have a large resource potential, wide distribution characteristics, oil is the stable yielding important reserve block. But the southern Changyuan Heidimiao oil and gas reservoir evaluation is very difficult, mainly manifested in two aspects:in the reservoir, manifested as the lateral change of the reservoir, sand body development is not continuous, objective layer single; in reservoir types, manifestations of structural lithologic reservoir and lithologic oil reservoir in. Through the anatomy of a typical block, comprehensive deposition, structure and hydrocarbon accumulation characteristics, that only the structure, sand body, reservoir organic matching can form favorable oil and gas reservoir. The application of AVO earthquake prediction, seismic spectrum detection of oil and gas, sedimentary facies and fine sand body anatomy and other technology, considering the structure, reservoir, fluid distribution and other control factors of hydrocarbon accumulation, carried out partition block, reservoir screening, evaluation of oil gas resource potential.Based on3D seismic data is a foundation, from the structure, the distribution of sand body, oil and gas and water distribution, oil and gas reservoir formation conditions and control factors of Heidimiao oil layer and gas potential were described, deepen the southern Changyuan Heidimiao layer natural gas reservoir geological knowledge, rich shallow oil and gas reservoir geologic characteristics research method, seismic identification method, and the combination of seismic and geological comprehensive evaluation method, put forward beneficial suggestions to development target and location, under the guidance of a step increase reserve evaluation and development work, to the south of Changyuan shallow gas reservoir evaluation, development to provide technical support.
