A novel ensemble learning method for crash prediction using road geometric alignments and traffic data

Journal of Transportation Safety & Security (2019)

Peijie Wu Xianghai Meng Li Song

As an important part of traffic safety analysis, crash prediction models using road geometric alignments and traffic data (CPM-GAs) have been regarded as the most classic way and can be used in stages of road safety evaluation and road operating and management. To improve the predictive performance of tradition CPM-GAs and avoid the overfitting problem of machine learning algorithms, a framework of CPM-GA based on ensemble learning theory and a new ensemble rule for connecting traditional models and machine learning models were proposed in this study. Results of the ensemble learning CPM-GA show that (1) classification and regression tree (CART) is recommended for important variable selection procedure before applying support vector machine (SVM), (2) machine learning models outperformed traditional models significantly in aspects of model fitting and prediction accuracy but are unstable in the sensitivity tests, (3) the new proposed ensemble method of traditional model and machine learning model can effectively improve the accuracy of traditional CPM-GAs by 10%–16% and reduce the variance of machine learning CPM-GAs by 12%–36% simultaneously. Finally, the ensemble method presented in this article may shed light on more research of crash prediction models based on ensemble learning theory.

New-Type Water Controlling Technology for Improving Production Performance of Offshore Heavy-Oil Reservoir with Active Bottom Water

SPE Annual Technical Conference and Exhibition (2020)

Baobing Shang Yigang Liu Xianghai Meng Jianhua Bai Huaxiao Wu

Abstract This paper introduces a new water controlling technology to manage water production and improve production performance in an offshore oilfield in Bohai, China. Q oilfield is a typical heavy oil reservoir, mainly developed by horizontal wells. One of the main challenges for the production is the high water cut. Most of the wells experience water breakthrough within one year after put into production and produce for long time with water cut higher than 90%. Besides, the strong anisotropism of the formation aggravates the water breakthrough and makes water control work more difficult. In 2019, a new combined water control technology was applied to manage water influx in horizontal completions. In this technology, the annulus between the wellbore and the inner ICD (inflow control device) /AICD (Autonomous inflow control device) screen is filled with light-but-hard particles. In this paper, the barrier built by the fine particles is called continuous-packer. The existence of this barrier plays a similar role to mechanical packers between each ICD/AICD screen, thus the axial flow of the produced liquid is prevented in the horizontal section. Besides, the ICD/AICD screen is equipped to limit the liquid inflow of each segment based on the design. The purpose of equalizing production profile of the horizontal section achieves through the cooperation of the continuous-packer and the ICD/AICD screen. Untill now, this new technology has been used in more than 6 wells in Q oilfield, including both producing horizontal wells with high water cut and newly drilled wells. The production results show that the water cut reduces about 10% and the oil production increases for the high water cut well. The water breakthrough time and the water cut increasing rate is slower for the new wells comparing with near wells. The successful application of this technology demonstrates its validity for the offshore heavy-oil reservoir with active bottom water. It also provides a new method for the water controlling work for the offshore wells in Bohai oilfield. A detailed plan has been finished to implement this technology in more wells in 2020.

Experimental study on horizontal-well multi-thermal fluid stimulation process in offshore heavy oil reservoirs

Journal of Petroleum Exploration and Production Technology (2020)

Yigang Liu Jian Zou Xianghai Meng Fayuan Zhou Hao Liu

Abstract The development of offshore heavy oil is sensitive and complex, which is limited by factors such as platform space, economy, pollution and security, so conventional thermal recovery techniques such as cyclic steam stimulation and steam flooding have difficulty in achieving favorable development effect for offshore heavy oil reservoirs. Horizontal-well multi-thermal fluid stimulation (HW-MTFS) process is a relatively new thermal recovery technique, which combines the multiple advantages of gas injection, horizontal well and thermal recovery process. In this paper, the HW-MTFS physical model was firstly designed. Thereafter, the influences of different factors on steam absorption along horizontal wellbore were studied by sand-packed model experiments. Finally, the development performance of horizontal-well cyclic steam stimulation (HW-CSS) process and horizontal-well multi-thermal fluid stimulation process was compared by two groups of physical experiments. The results indicate that different injection factors significantly influenced the steam absorption along horizontal wellbore. Compared with steam injection, the multi-thermal fluid injection could effectively improve the steam absorption along horizontal wellbore. The HW-MTFS process had a higher oil rate and production, and the recovery of HW-MTFS process was 42% higher than that of HW-CSS in three cycles.

Catalytic Reactions of C4 Hydrocarbons on the Fluid Catalytic Cracking Catalyst

Ranliao huaxue xuebao (2008)

Ping-Xiang Yan Xianghai Meng Chunming Xu Jinsen Gao

The catalytic reactions of C4 hydrocarbons on a fluid catalytic cracking (FCC) catalyst were studied in a confined fluidized bed reactor. The effect of reaction temperature and space velocity on product yields and distribution was investigated. The results show that the FCC catalyst has the good performance of aromatization and cracking of C4 hydrocarbons and can be used to produce propylene and aromatics under the suitable reaction conditions. It is mainly the butylene in the C4 hydrocarbons that undergoes catalytic reactions over the FCC catalyst and butane is hard to convert. Low reaction temperature favors the production of aromatics, while high reaction temperature favors the production of propylene. Low space velocity is beneficial to promote the conversion of butylene and the production of both aromatics and propylene. According to the bimolecular mechanism and reaction results, the reaction network for the catalytic reactions of C4 hydrocarbons on the FCC catalyst is proposed. The analysis on the this reaction mechanism indicates that the main reason of resulting in the lower yields of ethylene and propylene could be the poor secondary cracking performances of C5 and C6 olefins formed in the catalytic conversion of C4 hydrocarbons on the FCC catalyst.

Treatment Technology of Steam Breakthrough for Offshore Heavy Oil Reservoirs Developed by Huff and Puff with Multi-Component Thermal Fluid

Yigang Liu Jian Zou Xianghai Meng Xiaodong Han Yongtao Sun

Abstract The multi-component thermal fluid huff and puff pilot for offshore heavy oil has been conducted in Bohai Oilfield since 2008. Currently, part of the wells has entered the second cycle of the huff and puff. With the increase of the stimulation cycles, the steam breakthrough becomes serious due to the steam fingering and overlapping. In order to further improve the oilfield development performance, technology that could impede the steam breakthrough is developed. Experiments are designed and carried out for selection of suitable foam systems and the optimization of injection parameters in laboratory. And the temperature-sensitive gel is also developed for the steam breakthrough treatment which presents as liquid at normal conditions, begins to solidify at about 70°C and could become liquid again when the temperature decreases below 70°C. Then technology based on these two plugging agent are applied in the actual wells. The experimental results indicate that the selected foam system could meet the requirement of high temperature resistance and plugging strength. The injection mode of the foam system are all studied and optimized. Based on the experimental results and reservoir simulation, a project for steam breakthrough treatment in Bohai Oilfield has been designed by using both the selected foam system and the temperature-sensitive gel. The simulation prediction shows that this technology could achieve high oil increment for single cycle which indicates that this technology is efficient for impeding the steam breakthrough and improving the oil production rate. The actual field implementation has been conducted. This is the first time that this technology is applied for steam breakthrough treatment in Bohai Oilfield. This technology could provide useful guidance for treatment of steam breakthrough in offshore heavy oil reservoirs.
