| 1 | Characteristics and development model of karst reservoirs in the fourth member of Sinian Dengying Formation in central Sichuan Basin,SW China显示文摘The reservoir space,types and distribution characteristics of karst carbonate gas reservoirs in the fourth member of Sinian Dengying Formation(Deng 4 Member)in central Sichuan Basin are analyzed based on the drilling,logging and seismic data.A development model of karst reservoirs is constructed to support the high-efficiency development of gas pools.The research shows that the reservoirs in Deng 4 Member have mainly small-scale karst vugs and fractures as storage space,and can be divided into three types,fracture-vug,pore-vug and pore types.The development patterns of the karst reservoirs are determined.On the plane,the karst layers increase from 65 m to 170 m in thickness from the karst platform to the karst slope,and the high-quality reservoirs increase from 25.0 m to 42.2 m in thickness;vertically,the reservoirs at the top of Deng 4 Member appear in multiple layers,and show along-bedding and along fracture dissolution characteristics.The reservoirs at the bottom are characterized by the dissolution parallel to the water level during the karstification period,and have 3-5 large-scale fracture-cave systems.Based on the reservoir development characteristics and the genetic mechanism,three types of reservoir development models of karst reservoir are established,i.e.,bed-dissolved body,fracture-dissolved body and paleohorizon-dissolved body.The construction of karst reservoir development models and seismic response characteristics of the three types of reservoirs can provide parameter for well placement and trajectory design,and substantially improve productivity and development indices of individual wells and gas reservoirs.The designed production capacity of the gas reservoir has enhanced from the initial 3.6 billion to 6 billion cubic meters,making the profit of the reservoir development increase noticeably. | YAN Haijun HE Dongbo JIA Ailin LI Zhiping GUO Jianlin PENG Xian MENG Fankun LI Xinyu ZHU Zhanmei DENG Hui XIA Qinyu ZHENG Guoqiang YANG Shan SHI Xiaomin | 2022 | Petroleum Exploration and Development2022，49，4： | 1 |
| 2 | Advances in the Method of Production Performance Prediction of SRV-fractured Horizontal Wells显示文摘As the representative techniques of stimulating production performance,horizontal well and stimulated reservoir volume(SRV)fracturing are applied successfully in unconventional oil/gas reservoirs,such as Bakken and Eagle Ford,and will become the core stimulating techniques to exploit unconventional reservoirs in the future.In the process of horizontal well SRV fracturing, | REN Long SU Yuliang XU Chen MENG Fankun | 2015 | Acta Geologica Sinica(English Edition)2015，89，A01： | 0 |
| 3 | A Model for the Connectivity of Horizontal Wells in Water-Flooding Oil Reservoirs显示文摘As current calculation models for inter-well connectivity in oilfields can only account for vertical wells,an updated model is elaborated here that can predict the future production performance and evaluate the connectivity of horizontal wells(or horizontal and vertical wells).In this model,the injection-production system of the considered reservoir is simplified and represented with many connected units.Moreover,the horizontal well is modeled with multiple connected wells without considering the pressure loss in the horizontal direction.With this approach,the production performance for both injection and production wells can be obtained by calculating the bottom-hole flowing pressure and oil/water saturation according to the material balance equation and a saturation front-tracking equation.Some effort is also provided to optimize(to fit known historical production performances)the two characteristic problem parameters,namely,the interwell conductivity and connected volume by means of a SPSA gradient-free algorithm.In order to verify the validity of the model,considering a heterogenous reservoir,three conceptual examples are constructed,where the number ratio between injection and production wells are 1/4,4/1 and 4/5,respectively.It is shown that there is a high consistency between simulation results and field data. | Chenyang Shi Fankun Meng Hongyou Zhang HuiJiang Chang Xun Zhong Jie Gong and Fengling Li | 2022 | Fluid Dynamics & Materials Processing2022，18，5： | 0 |
