Jilin Oilfiled Has Developed Efficiency Evaluation Of Research

Enterprise's mission is to meet the social needs and make a profit. Enterprise business activities are also in order to meet the task. Any organization in any period of existence is in order to achieve certain goals, meanwhile, any organization at any stage goal activities all need combination and use certain resources, thus pay a price. Efficiency is refers to the achievement of organizational goals and realize the goal of price paid a proportional relations between. The pursuit of organization activities of benefit maximization is hard to less resource consumption to achieve organizational goals.High gas enterprises is a high-risk industry investment,. China has moved into onshore oil development period, the difficult exploitation, single-well low yield, high moisture content, investment costs sharply increased, steady-yield, difficulties, which requires us to ensure production in the meanwhile, the limited funds into efficient block, to achieve enterprise benefit maximization, reduces the risk of investment. This also makes benefit evaluation work in oil enterprise will become increasingly important. That is the essence of effectiveness evaluation of construction project in the whole calculation periods of economic activity, through the benefit and cost calculation of the project, the economic analysis and comparison. By analyzing the causes of failure of evaluation find success, summarizing experiences and lessons, and through the timely and effective information feedback for future new projects, the decisions and to improve investment decision-making management level, also suggested the project implementation to evaluate the problems in the operation provide improvements, improve the investment efficiency.Jilin oilfield is the typical "three low" oilfield, low abundance, low permeability and low porosity is the most obvious geological characteristics, development very difficult. The resulting crude million tons, increasing capacity construction investment, according to current headquarters issued calculate, we each investment criteria of 1 million tons capacity will be built more than 5 billion yuan formed in the long run, investment gap, could face no investment for development of situation; Jilin oilfield "more Wells low productivity, last year the average single well daily output has fallen to a ton of the following, if do not take effective measures, even playing again much new Wells, can make up for the decline, crude oil amount old well.qiaoying left is hard to stand, steady the company's value status would decline, the practical profits employees will not get safeguard; Meanwhile the listed business investment, will directly cause reduced unlisted business workload and the loss of income, at present the trend will aggravate losses, survival development would be threatened.This paper using benefit evaluation theory, through the establishment of effectiveness evaluation model, research jilin oilfield technical route benefit evaluation, summarizes the jilin oilfield efficiency evaluation method. Only analyze the influence of factors, to find a benefit to improve efficiency. Meanwhile, the evaluation index and evaluation method of the evaluation results directly affect choice accuracy. Comprehensive analysis of evaluation results, queuing screening, and effective guidance to oilfield development. For 2008 already develop gas fields in jilin oil parameter selection, the cost composition and influence factors analysis (including the operating cost structure and influence factor analysis and operation cost structure and the influence factor analysis), single well benefit evaluation, block benefit evaluation and single well sensitivity analysis, block sensitivity analysis, find the influence of the operating costs of jilin oilfield is mainly caused CaoZuoFei, depreciation, folding, differentiate to benefit costs, a block, benefit type block, benefit three blocks and benefit the block and invalid class of Wells, benefit type Wells, benefit three Wells and invalid Wells quantity, combing reservoir geologic conditions of the marginal benefit Wells, analysis of the causes, invalid Wells: 1, oil well itself yield normal, but due to reasons such as frequent workover that higher cost of underground work. 2, reservoir itself development is poor, oil production is low. 3, high yield, high water Wells liquid. 4, oil Wells and high water cut, and low yield. 5, because well conditions limit cannot implement stimulation measures and other reasons. The marginal benefit and ineffective put forward ideas: 1, well management to strengthen the key cost project management, especially in the operating costs of DongLiFei larger proportion of fuel, maintenance fee, material fee, optimize the investment costs, eliminate non-budgetary and non-operating expenditures. 2, during the guarantee production system under the premise of safe and smooth operation, according to the "overall deployment, implement step by step, tracking performance and developing steadily" principle, first to arrange scattered well or in production systems especially ground systems affect small marginal benefit Wells and invalid well shut-in. 3, in measures aimed at work, tapping reservoir characteristic, many choose low cost acidification of the measures to improve stripper well into the wellbore permeability, and strive to improve oil production. 4, implement abnormal Wells processing technology processes, building is not normal Wells, effectively reduce processing template reactive homework, reduced maintenance activities, reducing homework cost well times. 5, strengthen the operation management and quality tracking, improve operation time success. Effectively guide jilin oilfield have directional selection favorable bloc, the investment, avoid blindness production.
