Abstract

Petroleum migration, especially secondary petroleum migration, is an important content in the study of petroleum geology and yet a weak link. Since the 1990s, the following major advances in this area have been made: (1) a much better understanding of the mechanism of secondary oil-gas migration and accumulation has been got; (2) the design of modeling experiments or lab devices for secondary petroleum migration and accumulation is more scientific, and thus the experimental results are more believable; and (3) great progress in numerical simulation of secondary oil-gas migration and accumulation has been made. In-depth, integrated study and 3-D visualization simulating based on detailed geological investigation of secondary oil-gas migration and accumulation are the direction for the future study of this respect.

Fault block oil reservoirs are well developed in Linpan oil pool of the Huimin depression. But the sealing mechanism of fault is not clear. The fault cementation zone characteristics and its origin are discussed by means of core data, well logging data, physical property and scanning electronic microscope analysis. The subsurface water rich in Ca2+ and Mg2+ migrates from deep formation to shallow part along the fault zone during faulting activity in Linpan oil pool. Calcite and dolomite deposit along the fault zone due to the decreasing geothermal pressure upward. As a result, the permeability of the fault zone decreases about one order of magnitude and the accumulated oil is well sealed by fault cementation zone.

The discovery that major epsodes of subhorizontal, allochthonous salt flow have occurred in the Gulf of Mexico Basin requires a means of quantifying the evolution of allochthonous salt and associated structures to conduct both basin and petroleum systems analyses. Sequential structural restorations of allochthonous salt systems provide an evolving structural framework for integrating stratigraphic, geophysical, and geochemical data sets. In this stuey, interpretation of more than 10 000 km (6200 mi) of multifold seismic data, and sequential restoration of eleven profiles, were used to determine the geometry and evolution of allochthonous salt structures within Ewing Bank and northern Green Canyon protraction areas. The reults illustrate the complex geometry of the multilevel salt system and the types of interactions between counterregional and salt-stock canopy models of allochthonous salt system evolution. Sedimentary loading is accommodated by salt sheet extrusion, gravity spreading, gravity gliding, extension, salt evacuation, and contraction. Salt geometry commonly changes dramatically through time because it provides much of the accommodation for sediments and absorbs much of the extension and contraction within its overburden. The positioning and kinematics of extensional and contractional structures are controlled by salt body geometries, salt system interactions, and, most importantly, the topography of the base salt or equivalent walt weld. The structural restorations also constrain the timing of salt sheet and salt weld formation and document the positive correlation among sedimentation rates, salt flow, and structural deformation. Cross-section salt area generally decreases through time in areas of salt evacuation and minibasin formation, but increases in sections crossing growing salt bodies. Three-dimensional restoration is required to determine the three-dimensional kinematics and balance of allochthonous salt tectonics.

A coherent oil-migration model based on geomechanical considerations includes both the high-molecular kerogen structure and the capillary properties of source rocks. Oil is squeezed from kerogen by compaction following oil generation. This squeezing effect should be created by the differential stress (maximum compressive stress minus least compressive stress) acting on the kerogen which has been chemically broken up by oil formation. In sedimentary bodies whose water is at hydrostatic pressure, the migration of oil seems to involve two processes: (1) lateral transfer, by channeling into the more coarsely microporous layers of the source rocks, from the oil generation site toward the geologic structure or lower pressured zone; and (2) vertical transfer from source rock to reservoir by the opening or structural tops, where the least compressive stress is slightly greater than or equal to the pore pressure, and where the capillary pressure increment (2..gamma../R) of oil in the microporosity exceeds the tensile strength of the rock. In sedimentary bodies whose water is overpressured, the pore pressure should be governed by the least compressive stress and thus migration should begin by oil transfers in a system of small open fractures, and eventually in larger fractures. The theory demonstrates the impossibility of oil being transferred to the reservoir under true tensile conditions (negative effective compressive stress) and thus explains the large asphaltic veins of southeastern Turkey and the well-known bitumen veins of the Uinta basin.

A method called Oil Migration Intervals (OMI) is presented to assist identifying lateral oil migration pathways intersected inexploration boreholes. It predicts potential profiles of residual oil saturation due to partial confinement of oil below sealing strata using a pseudodisplacement pressure log and the buoyancy gradient.The OMI method performs calculations on wireline log data and uses empirical correlations between permeability and displacement pressure to derive a continuous pseudodisplacement pressure log for an intersection of reservoir or carrier bed. A pseudopermeability log is calculated from a modified Wyllie-Rose equation by replacing the irreducible water saturation factor with an empirical pore aperture parameter utilising V -Shale and Porosity. The pseudodisplacement pressure is subtracted from the buoyancy gradient to obtain profiles of potential excess buoyancy pressure and thus relative residual oil saturation due to partial confinement beneath sealing strata. The OMI log can then be directly compared with scaled field or laboratory measured oil show indicators to identify genuine secondary (lateral) oil migration. The steps in the calculation of the OMI log have been calibrated using laboratory and field data from exploration oil wells in the Timor Sea, NW Shelf, Australia.
