Henan Zhongyuan Chemical Co., Ltd. is a large-scale joint-stock enterprise engaged in the exploration and development of natural alkali and the processing and sales of related derivatives. Its predecessor, An Peng Soda Plant, was first discovered by Henan Oilfield and has been tested and developed on a small scale. At present, it is the largest natural alkali production base in China and even in Asia, which is jointly developed by Inner Mongolia Yikezhaomeng Chemical Group, Henan Oilfield and Tongbai County in the form of joint-stock cooperation.
As a social market outside the Sinopec system, this market is mostly shallow wells and vertical wells. In recent years, it was mainly undertaken by private enterprises and individual enterprises, and Henan Drilling Company withdrew as an inefficient market a few years ago. With the difficulty of expanding the production of this alkali mine, the alkali well has turned to horizontal well construction, and the construction technology has become complicated, and the drilling technology content is getting higher and higher, so private enterprises and individual enterprises can no longer meet the needs of the construction technology. Henan Petroleum Engineering Company firmly grasped this market change, carefully organized, and successfully won the bid for the horizontal alkali well construction project, with the contract amount of140,000 yuan. At the same time, it drove the logging and mud logging construction teams to enter the site together, promoted each other and developed in multiple disciplines.
Well HV027-8 is a vertical and horizontal compound well with a vertical depth of 2993 meters. There are karst mirabilite layer, high-pressure water layer, gypsum-bearing mudstone and alkali layer in the well body, and the formation is complex. It is necessary to connect two targets in the horizontal section and collude with two vertical wells, which requires very high drilling technology. Henan Engineering Company will adopt the characteristic technologies such as "drilling with needles" and new employment management mode, strengthen the coordination and process connection of drilling, logging and mud logging, scientifically organize production, and make every effort to build quality projects, so as to realize "drilling a well and expanding a market", laying a foundation for Henan Petroleum Engineering Company to expand the alkali mine market and cultivate new economic benefits.
