The Particular Strata Characterization Of Shen 179 Block In Liaohe Basin Damintun Oil Field

Aiming at the complex structure of the Oil reserve rock in Liaohe basin Jinganpu oil field Shun 179 block, this article apples the particular strata description, comprehensively uses the log geology, the sequence stratigraphy, the structural geology the petroleum geology and so on to deepen the study of the strata structure, the fault sealing, the reservoir heterogeneity, and according to this basic, know the contact relationships among the fault blocks in different banks and the strata distribution inside the fault blocks, know the distribution law of the remaining oil, establish the foundation for exploring the oil storing potential power.In the process of the oil field exploitations, the compartmentalizing and contrasting the high precision stratums are the key work in the strata study, the delicacy level of the compartmentalizing and contrasting the strata groups directly decides the depth and precision for recognizing a oil reserve rock. In the fine contrasting stratums, we apply well-tie seismic cross-section techniques in the contrasting and compartmentalizing, reasonably compartmentalize borderlines of the strata groups. In the same study of the conformation, we firstly control the faults status and the tectonic configuration, and then make control with the wells, carry out the distributing character of the combination structure, the fault and the fault blocks.The study of the sedimentary farcies and the micro sedimentary farcies is the base of the oil reserve bed study. With the analyses of the rack combination, sedimentary rules, and sandstone granularity and with the sediment symbols of the sedimentary structure, the ancient biology vestige and the electro-farcies and so on, combining the background of the ancient condition, we make sure that Shun 179 block is the second fore-edge farcies of underwater delta. In the rock core and the well logging, we can further divide them into the prime channel line containing the least-leg of the gravelly sandstone micro-farcies, the water branches containing micro-farcies of the fine sandstone, the micro-farcies sand-mud rock between water channels, micro-farcies of the fore-edge mud-stone patina send-flag.The character of the remaining oil distribution is the straight materialization of the strata description achievements. The geological facts of the distribution, the difference, and the influence of the remaining oil among or within minimum oiliness units are much more facts. So we must consider the distribution acreage, thickness, permeate rate, the tectonic site, the sort of sediment micro-farcies the rule variety of the reserve.
