The company has achieved phased results in the development of carbonate rocks in the Tarim Oilfield.

On the morning of October 13, 2013, the project "Description of Reservoir in Ha 6 Block and Research on Reservoir Engineering in Xinken-Rewapu Block" undertaken by Xinjiang Subsidiary of Hengtai Aipu Company successfully passed the final review of Tabei Project Management Department of Tarim Oilfield Branch. The company's post-doctoral project manager Wang Lianshan made a final report on behalf of the project team, and the project successfully passed Party A's acceptance with an excellent score of 90.8 points. This is another phased achievement after the excellent mid-term acceptance review of the project in August. The leading experts of Tabei Project Management Department and Research Institute fully affirmed the work and efforts made by Hengtai Aipu Company in the field of on-site integrated technical service in Halahatang Carbonate Oilfield in the past year, which well supported the production and scientific research work of Tabei and Research Institute, highly appraised many innovative and effective achievements of the project research, and put forward specific requirements for the construction and next development of the development team, the cooperation intention of the next stage project is clearly put forward.

So far, the company has made phased progress in the field of carbonate oil field development in Tarim Oilfield, including the project of "Harahatang Oilfield Development Database and Management Platform", which has been set up for research. The company has ushered in a gratifying situation of sustained and stable development in the field of Tarim carbonate development.

Faced with the world-class problem of fractured-vuggy carbonate reservoir development and the tense situation of continuous production in Tabei, Xinjiang's subsidiary company has intervened in advance since May last year and set up a young team led by development geology and reservoir engineering and technical personnel in time to cooperate closely with Party A and strictly follow the crude oil production requirements of Tabei Project Management Department and the scientific research needs of Exploration and Development Research Institute, it is divided into three working groups to actively carry out front-end services. Starting from the relevant technical theories of carbonate fractured-cave reservoirs, it strengthens the integration of geology, oil reservoir and oil production and multi-professional cooperation. Through a lot of in-depth and detailed work, it has completed special research on dynamic description of fracture-cave units in Block Ha 6 and preliminary development plan preparation of Xinken-Rewapu Block, and has achieved innovative results in crude oil degassing and water early warning, this paper summarizes and puts forward the research ideas of "four problems, two studies, four practices, four understandings and several countermeasures" facing the development of carbonate fracture-cave reservoir in Harahatang reservoir, and initially explores a set of applicable research methods and technical routes for the development of fracture-cave carbonate oil field. The research results have achieved good results in the application of scientific research and production sites in the oilfield. Party A has cooperated with Party A to complete the implementation and preparation of the two-phase production capacity construction and adjustment plan of the oilfield carbonate rock oilfield, 12 rounds of 67 new well location deployment, 6 rounds of 11 offensive measures optimization, reserve report, scientific research topics, reservoir evaluation, etc. A total of 38 wells have been proposed since 2012. Currently, 30 wells have been regular measures and 15 wells have been implemented, the success rate of the measures was 80.0, with a cumulative increase of 28000 tons of oil.

Through more than a year of unity and cooperation and day-to-day efforts, the carbonate rock development team has continued to grow, and a large number of technical backbones and good seedlings have been discovered and cultivated, which have been affirmed and welcomed by Party A. At present, the development team is stable and morale is high. Everyone is determined to make greater progress in the next stage of work and contribute their intelligence to the development of the company with actual results.

I would like to express my gratitude to Wang Xihua, the company's leaders at all levels and technical expert of the head office, who has been caring for the carbonate rock development project team. I would like to express my sincere thanks to the relevant leaders and experts of Tarim Oilfield Tabei Project Management Department and Exploration and Development Research Institute.
