Analysis of the main controlling factors of intra-well frac hit between deep coalbed methane in Daning-Jixian block and research on countermeasures to prevent and control it by Ming CHEN, Junyi SUN, Liwei WANG, Lizhu YU, Haonian TIAN, Dameng WANG, Xianfeng GU, Zesong YIN, Huan ZHANG

“…Then, based on the objective geological conditions of Daning-Jixian block and the understanding of development and production practice, using the multi-factor gray correlation analysis method, we evaluated four categories and nine sub-factors of influencing factors, such as development and deployment (distance between wells, location of horizontal section, vertical depth), geology (strength of natural fracture), engineering (average scale of single-cluster fluid, number of perforation clusters, scale of single-section fluid, and construction displacement), and drainage and extraction (production time of the parent well), the distance between wells, production time of the parent well, average single-cluster fluid size, and natural fracture were identified as the main control factors for the pressure frac hit of deep-seated coalbed methane horizontal wells in Daning-Jixian block, and corresponding preventive countermeasures were developed based on these factors. …”

An indoor positioning system based on distributed LTE network by Yu YANG, Ming CHEN, Daqing LIU

“…Indoor positioning technology has important applications in the business and security fields,but there are still existing problems with low positioning accuracy and high deployment costs.An indoor positioning system based on long term evolution ( LTE ) network was introduced.The system was defined on the Huawei distributed pico base station and was used to measure the reference signal strength (RSRP) or time of arrival (ToA) of mobile terminals to multiple access points.To overcome the uplink power control in LTE network,the absolute RSRP or ToA was converted to differential values.The system relied on widely deployed LTE networks to provide seamless location services to terminal devices in a wireless network connection state.It didn’t rely on third-party software or affect network performance.The experimental results show that the average positioning accuracy of Huawei indoor positioning system using time difference of arrival (TDoA) can reach 3~5 m in indoor scenarios such as shopping malls,showing good application potential.…”
