Practical special research

Achieve increased production and efficiency

The effective development of old oilfields is inseparable from the strong support of technology

The plant complies with the principle of "geological potential, engineering means, and economic benefit", and carries out water injection wells, horizontal wells, casing damage wells, profile control and water shutoff, shut down wells and resumption of production, and sand well management

Water plugging and profile control is an important means for old oilfields to improve the water absorption profile of the formation and to produce reserves that cannot be effectively produced

In order to slow down the corrosion rate of oil wells, technicians took the river area as the research object of oil well microbial anti-corrosion technology.

Process transformation and upgrading

Reduce application costs

The plant promoted the low-cost transformation and upgrading of engineering technology, and completed the transformation and upgrading of 5 technologies such as anti-eccentric wear, continuous operation, fixed pipe injection, low-cost plugging and water vapor pulse cleaning.

Conventional measures such as filling holes and water plugging have problems such as high cost and long production time.

In view of the high cost and poor economic benefits of the blocking acidification measures, the plant applied the immovable pipe string injection process.

Oil sludge accumulation and fouling in surface pipelines have led to an increase in the transportation pressure of the oil collection pipeline and the deterioration of water quality along the way.

Promote mature technology

Improve quality and efficiency

For more than 40 years, the first oil production plant has accumulated a large number of mature process technologies in production practice, such as process optimization, oil well separation, multi-stage and multi-stage injection, oil well anti-scaling and anti-scaling, and mechanical production optimization, which have achieved remarkable results in reducing costs and increasing efficiency

In order to reduce operating costs, the technical staff of the plant optimized the technological plan for construction purposes, combined with well conditions and historical operations, and promoted the application of construction procedures such as water plugging, optimization of wells, scraping, and leak detection.

The application of oil well separation technology can improve the production of interlayer interference oil wells.

In addition, the plant has continued to optimize mechanical mining parameters to achieve energy saving and consumption reduction.
