Assessing Methods Of SEC On Jilin Oil Reserves Of Low Permeability Reservoirs

China has access to the world trade organization, entering into the international capital market, and participating in the international energy competition. China’s three big oil companies have liste overseas, attract exploration and development funds, expand overseas market exploration and development, solve the high-speed development of the national economy and oil and gas energy shortage of conflict.as a listed company In the United States, ji lin oil field has a huge reserves of low permeability, which has caused the reserves of the corresponding evaluation and foreign disclosures must meet the requirements of the securities and exchange commission, the evaluation must comply with the provisions of the securities institutions resources reserve evaluation rules (hereinafter referred to as the SEC(rule)The results of the evaluation is to confirmed reserves of oil and gas reserves. Proveed reserves of oil and gas (hereinafter referred to as the confirm reserves)which is through the geology and engineering material analysis, under the current economy, government regulations and operation condition, from a given date and the known reservoirs have reasonable certainty of the amount of oil and gas exploitation can be combined. Policies and regulations refering to the contract should be production (mineral rights permit) period, unless there is evidence of this contract (mineral rights permit) automatic updates is there is a reasonable certainty. Development of hydrocarbons project must have begun to implement or operator must have a reasonable certainty in reasonable time frame the project will be implemented.high permeability oil field to the reserves of the evaluation method is not useful to the Low permeable lithologic reservoir,because Low permeable lithologic reservoir have some advantages of complex heterogeneity, interlayer heterogeneity, plane heterogeneity,Iin the evaluation process, we will meet such problems:how to divide the reasonable in low permeable lithologic reservoir calculation unit? What will you pay attention to? how to determine the more reasonable Low permeable lithologic reservoir reserves that well control degree and oil area of? The diminishing curve method of how to select the reasonable rate, and the reservoir permeability relations how to rate, what is the reference and guidance significance? Reserve calculation within the unit reservoir added together computing reserves the rationality of deficient. Therefore, need through the actual situation, set up with practical significance reserves assessment. First,ji lin oil field choosing the representative of the block from established SEC standard analogy reservoir sequences to evaluate the permeable lithologic reservoir. Evaluation needs to collect the static and dynamic development material of data collection and sorting, successive to reserves calculation units classification, the oil, how to sure the effective thickness, oil saturation sure, porosity determination, volume coefficients determined to determine the density and crude oil, and this method to determine the dynamic rate, determine the recovery. Suitable for jilin oilfield and get the low permeable lithologic reservoir reserves of evaluation methods, for the following reserves lay the foundation for the assessment.
