Prediction Of Heshui Oilfield In Jurassic Favorable Area

China Erdos basin is the second largest sedimentary basin on land, The basin area of25*104km2, Multiple oil-bearing formations, Exploration field is very wide. The Jurassic andTriassic Mesozoic petroleum has two major oil-bearing series, Total oil resources of85.88×108t, The basin reserve resources, Exploration potential, and is currently in a period of greatdevelopment, so in an extremely important position in the development of strategic pattern ofChina’s oil and gas, as the key for increasing productivity. Since seventy’s,Petroleumexploration in the basin has made significant achievements, formed a series of Jurassicpaleogeomorphological reservoirs and lithologic reservoirs of Triassic delta theory, butprogress has always been a fine tradition of oil, Especially the current worldwide energy crisis,The oil and gas resources condition showed its strategic importance, So looking for back-upblock exploration and production capacity construction is a very urgent.Since the Jurassic reservoir buried depth, the development of good effect, is the reality ofdevelopment put into production line, therefore in the Jurassic reservoir enrichment regularityand the oil-bearing strata reservoir enrichment characteristics basis, further to well area as aunit、“Exploration wells、Evaluation wells、Development wells” three combined with fineanalysis and evaluation as a means of establishing favorable area is very urgent and necessary.Through the systematic analysis of the main reservoir of Jurassic Heshui Area of Sedimentarymicro facies、Reservoir characteristics, to summarize the enrichment laws of oil reservoirs;Combined with the exploration、evaluation and production construction with achievements，fine evaluation of reservoir of Jurassic in the area built favorable area，the solid foundation foroilfield production.
