Controlling the uncertainty in reservoir stochastic simulation

Petroleum Science 2010年第4期7卷 472-476页

Unexpected noise in reservoir stochastic simulation realization may be too high to make the realization useful, especially when there is a lack of hard data. Through discussing the uncertainties, we present two ways to control the uncertainty ratio that is brought by the algorithm of stochastic simulation. By reasonably reducing the random value of the stochastic simulation result, the unexpected values introduced by the residual that associates with random series can be controlled. Another way when the data disperse unevenly is to control the stochastic simulation order by grouping the points that need to be simulated to make those points which can be simulated by more neighborhood hard data calculated first. Both methods do not go against the core stochastic simulation algorithm.

The development and research on the recycle demetallating process are introduced. It shows the recycle demetallating process is effective on removing metal elements in heavy crude oil, especially with regard to calcium, through commercial application in delayed coking unit. Finally, the ash content in petroleum coke can be decreased to less than 0.5%, which complies with the IB coke standard. At the same time, the recycle demetallating process is an environmentally friendly technique, which has little effect on production quality and equipment corrosion.

NH4. zeolite was prepared through ion-exchange of NaY zeolite with an ammonium salt. Then LaY zeolite was obtained through a secondary ion-exchange of NHaY zeolite with a rare earth salt solution followed by calcination of the zeolite product. Dynamic adsorptive desulfurization of naphtha was conducted in the presence of the modified LaY zeolite, and the sulfur content of the treated naphtha samples was analyzed by microcoulometry. The test results showed that under dynamic conditions the LaY zeolite prepared through secondary ion-exchange of NH4. zeolite, which was prepared using 1.0 mol/L ammonium salt, with the rare earth salt exhibited a better desulfurization efficiency. Furthermore, the LaY zeolite achieved a best desulfurization effect at an adsorption temperature of 4. ℃ and an adsorbent/oil ratio of 1：2.

The purpose of this paper is to discuss the poly-phase salt tectonics and its relation to the hydrocarbon accumulation of the Tarim superimposed basin. Several salt sequences are developed in the Tarim basin, they are: (1) the Mid-Early Cambrian salt sequence, mainly distributed in the west part of the north Tarim uplift and Keping uplift; (2) the Early Carboniferous salt sequence, mainly distributed in the south slope of the north Tarim uplift; (3) the Paleogene salt sequence, mainly distributed in the mid-west part of the Kuqa foreland fold belt and north Tarim uplift; and (4. the Miocene salt sequence, mainly distributed in the east part of the Kuqa foreland fold belt. The salt sequences deposited in the tectonically calm scenario, while the salt layers deformed during the period of intense tectonism. Although the salt sequences are characteristic of plastic flow, the differences of salt deformation styles exist in the different salt sequences be-cause of the different deformation mechanism. It is attractive that the distribution of the large oil-gas fields or pools has a bearing upon the salt sequences and salt structures, such as the Tahe oilfield related to the Lower Carboniferous salt sequence and laterally facies changed mudstone, the Kela No.2 gas field to the Paleogene salt structures, and the Dina gas field to the Miocene salt structures. It is indicated that the large-scale hydrocarbon accumulation is con-trolled by the poly-phase salt sequences and structures. The deep analysis of the poly-phase salt tectonics is helpful to understanding the characteristics of the structural deformation and oil-gas accumulation of the Tarim basin.

Study on Novel HIGEE Technology for Synthesis of Overbased Petroleum Sulfonate Detergent

引用

china Petroleum Processing & petrochemical Technology 2006年第4期8卷 29-39页

作者： Luo Lailong1 Zhang Youlin1 Bai Shengjun1 Qian Zheng1 Wu Wei2 Chu Guangwen2 (1 petrochemical research institute of petrochina Karamay petrochemical company, Karamay 834.00 2 Beijing University of Chemical Technology, Beijing 100029) petrochemical research institute PetroChina Karamay Petrochemical Company Karamay 834000 China Beijing University of Chemical Technology Beijing 100029 China

An innovative idea was proposed to prepare the overbased nano-sized calcium carbonate-calcium petroleum sulfonate in-situ the HIGEE reactor. The test sample prepared by this technology could meet the requirement of the industry standard SH004.-91 for the first-grade product on a par with similar overseas product. The test results obtained upon observation under microscope after freezing etching of specimen revealed that the crystal size of colloidal calcium sulfonate was in the range of 10-30 nm with an average size of 20 nm. The size of the detergent additive was uniform with good transmittance and fluidity. The HIGEE technology possesses five specific features as shown below: Firstly, the carbonation reaction is completed in one step with the reaction time reduced by more than 50% as compared to traditional batch reactor process along with enhanced reaction efficiency, good operability of the process and stabilized product quality. Secondly, ammonia emitted from the reaction is used as the co- promoter without the need for adding ammonia and water as promoters to simplify the promoter system along with effective and strong coupling of reactions. Thirdly, the utilization rate of Ca(OH)2 and CO2 is increased by 15% and 30%, respectively, with product yield increased by 15%, and calcium residue decreased by 65%. Fourthly, the HIGEE technology is environmental benign because of gasoline is used in this technology instead of toxic toluene and xylene. Fifthly, the dimension of HIGEE reactor is reduced by above two-thirds. The success in development of this new technology will offer new ideas and technology platform for the synthesis of metal detergent additive to lubricating oils in china.
