The Researching On Development Of The Remaining Oil In The Test Site Of Shanshan Oil Field

According to the geologic characteristics of the research area, make full use of coring well data, logging data and field dynamic, static database, the distribution of oil-water and the remaining oil in the test area of Shanshan oilfield are studied.Based on the small layer contrast of Shanshan oilfield, using comparison techniques and sedimentary unit comparison method, which describes the different types of sedimentary facies and the microfacies combination of delta sedimentary of Shanshan oilfield, on the basis of single sand body division. By comparison with the results of previous studies, the connectivity using dynamic oil-water well production dynamic data, verify the rationality of the sub layer, which fixes some previous hierarchical results, connectivity of understanding more accurate. Based on the geological knowledge, combined with the characteristics of fluid seepage test, the interpretation of well production dynamic and combined with logging, logging curve shape and combination of qualitative analysis of oil-water relationship, then use edge testing well test oil conclusion and logging information and the corresponding, to establish discriminant chart in oil layers, and given that most well zone with production data, the initial production data to validate the well logging interpretation. On this basis, collect test all the logging data, the logging interpretation model of logging interpretation, two times of the test area, according to a well test interpretation results to verify the accuracy of the selected model well. Ultimately concluded that the test area of oil and gas accumulation in the high position of the structure, the lower part of water; in the plane:the reservoir distribution in the study area in Central China, from the middle to the study area around the reservoir transitional oil-water layer and finally into the water. After the research, production characteristics of the test area to conduct in-depth analysis, summarized the water oil displacement efficiency and production rules, to find out the main factors which effect, so as to establish the model of the distribution of remaining oil, and provides a basis for the next step to carry out adjustment of development in the test area.
