Research The Dagang Oilfield Gangxi Reservoir Economic Boundaries

In Dagang oilfield as domestic oil and gas exploration and production base, port on the development of west of reservoir the development of China's oil industry, but made a contribution as oil downstream users continues to expand, oil demand has increased dramatically in Dagang oilfield development, put forward higher request, in order to meet the demands of the development of the social and political shall undertake the responsibility, the increase in Dagang oilfield exploration efforts, find new breakthrough and found at the same time, pay great attention to the exploration mature reserves resources evaluation, establish a rational economic boundaries evaluation system, make have found reserves resources get reasonable effective development and utilization in Dagang port for west reservoir is particularly important.This essay, taking dagang port west reservoir exploration in the process of developing the economic limit for research object, this paper summarizes the current deep reservoir exploration and development of the situation, and then analyzed in Dagang port west reservoir economic reserves of influencing factors, based on the economics principle, application of technology in set up many can assign values of parameters, established under the condition of economic reserves, single-well daily output and reserves abundances of the economic limit evaluation mathematical model. Then according to the three economic limit evaluation mathematical model for its parameter and calculated the assignment in certain depth well (1000m-3500m), traps area (5 Km2-80 Km2), well spacing density (2 mouth/Km2-10 mouth/Km2) and price (2000 yuan/ton-5000 yuan/ton) economic reserves, single-well daily output and reserves abundances of the economic limit.We according to the actual reservoir in Dagang port west establish data, applying the economic boundary evaluation model in different parameters obtained under large economic reserves, single-well daily output and reserves abundance of economic limit, finally using statistical software SPSS respectively to calculate the data analysis, found economic reserves, single-well daily output, reserves abundances and price, well depth, well spacing density and traps area is highly related relation, and obtained by economic reserves, single-well daily output and reserves abundance as dependent variable, as well depth, price, well spacing density and traps area as the independent variable linear correlation model. For in Dagang oilfield port west reservoir exploration and extraction has reference, this paper also reservoir exploration in the process of developing economic reserves of various reservoir boundaries study after the exploration and development research and technical economy evaluation all have certain reference significance.
