Study On The Geological Reserves And Development Potential Of The Saling Oil Formation In Sazhong Development Area

SaLing reservoir of Daqing placanticline middle oil as the top of the reservoir, since the oil field development has been viewed as a non-major reservoirs, there is no in-depth system. Although a large number of producing wells were also drilled SaLing group, but less information coring drilling environment (mud density, mud resistivity and so on) changed greatly, logging family complex, making accurate interpretation difficult to raise the effective thickness and thus affect reservoir evaluation. To implement Saling oil reserves, mining oil potential, it is necessary to carry out Sazhong SaLing potential oil reserves in research and development to enrich and improve the theory of continental oil field development.The paper take Sazhong in the development zone as an object, using the core sample, tests a newly drilled oil well, material and so on oil well logging, uses the synthetic study description method, to SaLing the oil layer structure, the reservoir connection condition has conducted comprehensive, system's research and the appraisal. Analyzes SaLing the oil layer the lithological character, the nature, oiliness and the electrical relations, the development effective thickness natural standard and the electrical standard; The establishment oil well logging computation effective porosity, the primitive water saturation model, to effective parameters and so on porosity, primitive oil saturation carries on the reasonable value, simultaneously to solve SaLing the reservoir low oiliness rank core sample and oiliness, the routine sampling reflected with difficulty not continuously the actual core sample oiliness characteristic the question, has used the close sampling and the routine sampling contrast, proposed the deviation factor adjustment method, applies the effective porosity, in the primitive oil saturation computation, causes the effective porosity, the primitive oil saturation value to be more accurate. Comprehensive geological and the oil well logging parameter two aspect's research results, the application volumetric method calculates SaLing the oil layer the geological reserve, and carries on the appraisal to its development potential, the oil layer the step development deployment work provides the reliable basis for SaLing.
