News from China Petrochemical News "In January, the daily oil increase effect of the HH36P95 well has been stabilized at 2.
Since the beginning of the year, the Development Research Institute of the First Oil Production Plant has taken "fast breakthroughs, fast tests, and fast production" as the important task, and is problem-oriented, aiming at the annual mission goal, "precisely", and further deepening the understanding and development of reservoir geology.
Carefully deploy to advance reservoir research and test
"The development method directly affects the development effect of the oil field.
According to the current low-energy and low-yield status of Chang 8 and Chang 9 major oil reservoirs in Honghe Oilfield, the institute has prepared early arrangements for the planning and deployment of the "Honghe Oilfield Chang 8 and Chang 9 Vertical Well Lateral Drive Water Injection Test Program", using the current existing vertical wells Combining with the ground conditions and understanding of the results in the development test, continuously optimize and expand the test, transform the results into productivity, improve the development effect, and raise the level of development technology.
They seek to take the initiative in development and testing, set up a development and test project team, concentrate their superior forces to carry out research and experimental research, scientifically formulate research plans and phased test targets, ensure that the arrangements for stable production and increase production wells are specified, and each technician The actual work of the development test project is divided, and the test is specifically implemented to the people.
Fine water injection promotes the revitalization of reserves in old areas
"Not long ago, the company's key scientific and technological research technology-"High Pressure Lateral Drive Technology" undertaken by the Development Research Institute won the silver prize in the annual special labor competition for the company's annual breakthroughs.
The water injection of Chang 8 reservoir in Honghe Oilfield is mainly concentrated in old areas such as HH105 and ZJ25.
In order to further revitalize the reserves in the old area and improve the waterflooding recovery rate, technicians are constantly looking for the cause of the disease.
Since the beginning of this year, the technicians of the institute have been adhering to the principle of “success one piece, popularizing one piece”, combined with reservoir characteristics and previous waterflooding test results, continuously optimizing test parameters and research directions, and carrying out high-pressure and large-displacement lateral drive and horizontal wells at the same time.
"These research tests have further expanded the technical methods for improving the waterflooding development of fracture-porous reservoirs.
Precise measures to help oil wells release productivity
"Oil well huff and puff can solve the problem of no fluid flow in a single well, but there are no clear relevant parameters to learn from.
In this regard, they strengthened the research of geological oil reservoirs, by constantly combing the reservoir characteristics and construction parameters of huff and puff wells, looking for possible clues in the huge data, adjusting and evaluating them; and carefully summarizing each parameter through continuous field tests.
"Among the 31 wells implemented this year, the proportion of wells with cumulative oil increase of more than 100 tons increased by 24.
In addition, the technicians of the institute have continued to increase the intensity of field tests to research key technologies for improving oil recovery in pore-type reservoirs.
