Analysis And Application Of Crude Oil Production In Oil Field Development

In the process of oil field development, the maximization of economic benefits has become the main target of oil pursuit. After the initial exploration, In order to ensure the economic benefits, in the oil and gas reserve economic evaluation should be done at the same time, so that each new production of oil has economic output from the beginning, and is the premise of the decision after the cost-effective, and in the economic evaluation of oil field, the single well yield is a very important parameter finally, evaluation of the effect of economic size and oil it directly affects the development and construction investment of gas. Therefore, how to calculate the economic output of crude oil in each stage of oilfield development to ensure the maximum economic benefit need to be resolved.This paper is to analyze each stage of oilfield development production of crude oil and its application as the research object. The first is the analysis of the four law of diminishing rate of crude oil, and then on the exploitation of oil, mining, mining early middle late yield were studied in each period, economic yield of crude oil, so as to ensure the maximum economic benefit. The early production period on the basis of influencing factors, establishes the dynamic break-even analysis model, the economic output of crude oil exploitation stage was determined; Then the application of calculating method of mining middle drawing Lorenz curve and the Gene coefficient to analysis of oil production, established the uneven nature analysis model, be not balanced between production wells of oil field and oil yield, unbalanced degree is different in each oilfield, the Interim Measures on calculation method of determining yield the best time and stimulation measures analysis, which can grasp the production time, ensure the benefit; Late in mining through the establishment of model for water content, water content is found to shut-in limit index, which provide a theoretical basis to do well in decision making.We analyze the results of the study based on the three stage of mining oil constant can be seen in the different stage of mining calculation of economic output using different methods need, must through the analysis of single well yield of oilfield factors on each stage, the corresponding mathematical model is established to calculate method, single well yield corresponding production period of oilfield, oil field in the economic evaluation, combined with the actual situation in various stages of their oil, in order to select the development investment of different block or field, in order to achieve a reasonable development to obtain the maximum economic benefit.
