Iraq AHDEB Oilfield Surface Construction Project

The Middle East is a global oil and gas rich area and a high-end market in the oil industry, and its status is very important.

This project is an important breakthrough in the Middle East strategy of CNPC, and the whole world is paying attention to the performance of the Chinese in the Iraqi oil market.

Several requirements are put forward for the preparations: 1. The EPC team should be further internationalized; 2. The two sides should further strengthen exchanges and communication in order to make full use of the mature experience and resources obtained in Iraq in the early stage; 3. All work should be planned in advance, especially the relocation of personnel and materials must be prepared two months in advance, and the impact of various unexpected factors on the project must be fully considered.

Iraq's Halfaya Oilfield is located in the south-central part of Iraq, between Numaniyah and Kut Town in Vast Province, about 160km away from the capital Baghdad. The first phase of the 3 million tons/year capacity construction project of the Ahdab Oilfield is the establishment of the new Iraqi government. The first new production capacity project and the first post-war foreign oil cooperation project recovered after the war. The investment of Oasis Petroleum Company, a joint venture of PetroChina and China North Industries Corporation, is about US$3 billion, and the contract period is 23 years.

      In this project, hiltech provides Float level meter, pressure transmitter, Rotameter Flow meter, high and low voltage power distribution systems for Halfaya Oilfield, including high-voltage mid-mounted switchgear, 33KV box-type transformers, MNS drawer cabinets, JXF non-standard boxes and GGD.

      Since the high and low voltage power distribution system of Halfaya Oilfield was put into operation, the work has been stable and reliable, and the performance is superior, ensuring the realization of 3 million tons/year production capacity.

      Among the halfaya oilfield after-sales service manufacturers, our after-sales service team has won the recognition of oil companies with solid technology and hard-working spirit, and was rated as the best after-sales service manufacturer.

Overcome world-class challenges

Continuous technological innovation helps achieve peak output. The development plan is the guideline for oilfield development, which directly determines the success or failure of oilfield development. According to the needs of oilfield development and business, the project team constantly adjusts the development plan to ensure win-win cooperation, and finally realizes the integrated deployment of technology and business.

International oil companies that have been operating in the Middle East for many years generally believe that the huge thick carbonate reservoir is like a thick sponge, filled with crude oil evenly, and the whole is massive, and a set of layered perforations can be found in the effective interval. Development can get better development effect. However, the experts of the Halfaya technical team, through the detailed description of the cores of nearly 2000m from multiple coring wells, through the calibration of the logging curve and the comparative analysis of multiple profiles, combined with the production performance, it is clear that the huge thick carbonate reservoir is not a block It is a thick sponge, but is characterized by interlayered sandwiches separated by many hidden partitions and interlayers similar to "cement slabs". These partitions and interlayers seriously affect the movement of oil and water, and must be developed in layers. The innovation of geological understanding that the huge thick carbonate reservoirs have hidden barriers and interlayers has brought breakthroughs in development concepts and changes in development methods. The development of Halfaya Oilfield has abandoned the general development method of a set of layer systems commonly used by international oil companies. Turning to the implementation of layered water injection development, the reserve production degree can be increased by more than 70% from 40%, which greatly improves the recovery rate and development efficiency.

Faced with the complex reservoir characteristics and special stratified development needs of the Halfaya Oilfield, the project team innovatively applied a number of advanced technologies and created a number of first achievements: in order to increase the thickness of the oil production profile of a single well, the project team successfully Completed the first multilateral horizontal well in Iraq; in order to ensure high and stable production of unconsolidated sandstone reservoirs, the first use of composite sand control technology such as gravel packing in Iraq achieved remarkable results; in view of the high gas-oil ratio and low water-cut characteristics of the reservoir, the company successfully The first gas lift oil production experiment was carried out, which effectively reduced the cost; for ultra-low permeability oil reservoirs, the first hydraulic fracturing well in Iraq was successfully implemented, revitalizing a huge amount of low-permeability and ultra-low-permeability reserves.
