normal compactionの例文

• Through studying it is shown that in chagan sag , the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion , lithology and underground water behaviour ; there are three types of mudstone compaction , i . e . normal compaction , undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs , i . e . normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity , hydrocarbon generation , widening on oil and gas exploration domain and selecting exploration targets , etc
• Research indicates that this idea is also applicable for the carbonate . to set up a suit of idea of travel time reading of carbonate interval and use real pressure data to correct it during plotting the normal compaction trend curve are rather important . the method is applied to the prediction of formation pressure in luojiazhai and dukouhe oilfield successfully
