White Horse Yaoxian Tower-Luo Pang Tableland Region Reservoir Description

Based on the analysis of all kinds of information, the study area is inthedevelopment stage of evaluation, reserves are abundant, but the geologicalcondition is complex, oil-bearing formation, vertical and horizontal heterogeneity, oiltesting well ratio is small, low yield. In order to improve the oil reserves extent, toensure that future oil production continues to increase stability, the oil extractionrate reached areasonable level, realize the yield and production target.Through the use of the study area of well logging data, drilling data andcoreanalysis data, made fine division and correlation of the small layer on the Chang4+5and Chang6and Chang8reservoir, sedimentary facies and distribution of sandbody, reservoir characteristics and reservoir evaluation studies, according to the maincontrol reservoir characteristics and reservoir formation factors in the study area oflogging curves two times to explain and reserves recalculation, and evaluatesthe reservoir, the reservoir for the final evaluation of deep and extra low porosity andextra low permeability, low and ultra-low abundance, medium-sized reservoir.
