Research Of Detailed Structural Interpretation In Daqing Putaohua Oilfield

This paper taking Putaohua oilfield in Daqing as an example, discusses the application of three-dimensional sectors-connecting high resolution seismic data interpretation and low-level tectonic sequences, in combination with drilling and fault to develop dynamic data are already oilfield development, the structure of the reservoir description, thought, method and content.Putaohua oilfield is Daqing Changyuan second-order tectonic belt south, one of the biggest tectonic structural toward the south tower structure for Aobao outspread part. Putaohua oilfield in 1979, Putaohua oilfield development since 1999, put into comprehensive development adjustment stage. With the further exploration and development of oil fields, minor fault blocks, small sand body and hidden trap forming reservoirs become oilfield of rolling extension, 5-10m target range of low amplitude structure, broken away from 3-5 m low-level sequence faults, 1-2m thin sand body of oilfield development of injection-production patterns and residual oil distribution and become plays control potential residual oil target. Using three-dimensional high resolution seismic data of the oilfield development on structure and low sectors-connecting sequence of oilfield, study the development adjustment rolling extension and deploy play an important guiding role.Taking high resolution of 3-D seismic data interpretation, application of peripheral oilfield has rolling extension and internal residual oil combined, full potential seismic data in oilfield development and fine role in reservoir description. Main USES of seismic data interpretation, coherent body of data section explains, 3d visualization body interpretation and fault of technology and mapping technique, variable shall finish the three-dimensional sectors-connecting Putaohua oilfield of seismic data interpretation and tectonic mapping, carry out a lot of faults and low amplitude structure, small fault block and broken nose. In sectors-connecting of 3-D fine structure interpretation on the basis of geological and low oil fine structure based on research achievements of amplitude, adopt various low-level sequence fault earthquakes material identification and interpretation techniques, implement the structural study of low amplitude of the fault block 4, 5 faults. Paper and then according to the structure of three-dimensional sectors-connecting described the research achievements in construction and fracture characteristics of traps, and meticulous description of the elements are analyzed, Putaohua oilfield of reservoir area, the Portuguese I local structural characteristics, combining the characteristics of structural evolution, the development and the reservoir type and hydrocarbon accumulation characteristics, The research of tectonic zone of low amplitude, low fault distribution characteristics of sequence with dynamic data analysis of oilfield development sequence of development of the lower fault. Based on the three-dimensional sectors-connecting paper structure and low sequence of fault proposed research achievements of Putaohua oilfield construction advantageous area and the periphery of the structural study of low amplitude of fault block potential targets.
