Luo ping-ya, male, Han nationality, a Communist Party member, was born in July 1940 in Changlong Sichuang Province. Professor, the tutor of doctor, the academician of the Chinese Academy of Engineering, the Former President of Southwest Petroleum University, the Former Director of the Academic Committee in the State Key Laboratory of "Oil and Gas Reservoir Geology and Exploitation" . For the past 40 years, he has been committed to the teaching and research on the exploration and exploitation of Oil and Gas and has Obtained lots of great achievements on fields such as, drilling and completion fluid technique, reservoir protection technique, theory and application technique on oilfield chemistry. These achievements are mainly summarized as follows: First, study on deep wells drilling fluid with high temperature resistance: In the mid-1970s, he proposed to improve the performance of the mud taking the advantage of high temperature and established the new ultra-deep mud system (anti-high temperature sulfonated mud system) of "the more deep the well, the higher the temperature, the longer the action time, the better the performance, the more simple the process, the lower the cost " , providing the necessary technical support for the success of deep well drilling. This system is still the main component of deep well mud technology in China and has been widely used.Second, Polymer Mud Technology: During the 1980s, he advanced that amphoteric polymers can be used for drilling mud agent and developed a series of new polymer treating agents and matching technology, which is one of the main components and development direction and is still being widely used. Third, Drilling and Completion fluid technique for reservoir protection: He proposed the point of shielding temporary plugging technique for reservoir protection and developed matching technology series, which solved the reservoir protection problems when drilling in oil layers using drilling fluid under positive pressure gradient and made great economic and social benefits. This technology is still being widely used. Fourth, the development of water-soluble polymer with heat and salinity tolerance, anti-shearing, efficient and viscosified: It provides the necessary theoretical basis and material guarantee for the establishment of various of displacement fluid system which is suit for enhancing recovery by chemical flooding in China.Besides, he also obtained great achievements on hole stabilization, horizontal drilling technology, oil-displacement mechanism by chemical flooding, application of seepage of physical chemistry, reservoir protection technology during oil production, Theory and Application Techniques of oilfield applied chemistry engineering and so on.He has presented and accomplished more than 40 research tasks belonging to Ministerial and provincial levels and obtained more than 30 awards of science and technology (including excellent teaching achievements) of which include 7 national awards and 13 Ministerial and Provincial Level awards( of which 3 are rated as CNPC ten annual excellent results ) and published 6 works and more than 100 papers, as well as cultivated more than 90 masters and doctors.Since he has obtained series of outstanding achievements both in scientific research and teaching, he is commended 6 times by government and rated as model worker and advanced teacher belonging to Ministerial and Provincial Level. He was granted as A NATIONAL JUNIOR EXPERT OF OUSTANDING CONTRIBUTION in 1986 and was approved AN EXPERT ENJOYING SPECIAL GOVERNMENT ALLOWANCE in 1990. He obtained Sun Yue-qi Energy Award in 1993 and became the academician of the Chinese Academy of Engineering in 1995. He is also the member of the third and fourth subject review groups of the State Council High Degree Committee, the member of High Degree Committee in Sichuan province, deputy to the sixth and seventh NPC, deputy to the sixth Sichuan provincial Party Congress and the 2000th national advanced worker.
