Romashkinskoye oil deposit: description, history, characteristics and features
Romashkinskoye oil field is included inthe top ten supergiant according to the international classification. When developing methods of oil production, Russian scientists made a number of discoveries, created unique technologies used in the world practice of mining and exploration of minerals. The deposit has been in operation for more than sixty years, but its potential is still huge and not fully known.
The discovery of Tatar oil
In the twenties of the last century, with the firstSoviet government began exploration of Tatar oil. The first expeditions that went on a mission to find deposits were not successful, but already in 1930 the approach to research became more focused and motivated. The new attempt was related to military actions and the threat of the seizure of North Caucasian deposits by Germany.
The search was protracted, the first explorationoil began only in 1941. Three years later, near the village of Shugurovo, when drilling a well, it was possible to obtain an inflow of industrial scale oil - 15 tons of raw materials per day. The deposit was named from a settlement near which a well was being designed. Shugurovskoye deposit, became the starting point in the history of Tatar oil, and also prepared a big surprise for the discoverers.
The giant near Romashkino
In 1946 Romashkinskoe oilfield. Where is the giant that made Tatarstan one of the most important industrial regions? Twenty kilometers from the Shugurovsky oil field, near the village of Romashkino (today the city of Leninogorsk is located here). For reconnaissance purposes, a well was laid, which after two years of drilling gave results that exceeded all expectations. During the exploration work, the Devonian layer was managed, and on July 25, a fountain of oil was debited from the well with a debit of more than 120 tons of production per day.
The discovery of the Romashkinskoye field broughtThe Stalin Prize for oil workers. Subsequent studies of the potential of oil deposits have shown that the Shugurovskoye field is part of the Romashkinsky deposit, and the structure of the natural storage is multi-layered. The production of oil on an industrial scale began in the 50's.
As it turned out later, the geologists discovered one of themysterious deposits. Initial estimates of the deposits were estimated at 710 million tons of oil, now production reached 3 billion tons. Experts note the pulsating state of the wells, which periodically empty out and refill, no one can explain this phenomenon so far.
After conducting a large-scale study of the potentialoil-bearing layers, scientists have come close to understanding how the Romashkinskoye oil field has developed and what potential it holds. The description of the tectonic indicators refers it to the Sok-Sheshminsky shaft. The geological estimation of the volume of oil is equal to five billion tons, and a reasonable reserve of reserves and the amount of extracted raw materials is equal to three billion tons. The depth at which modern development is carried out does not exceed 1.8 kilometers. The dimensions are roughly estimated and are within 65 x 75 kilometers. The starting volume of each well is about two hundred tons per day.
Romashkinskoye oil field onThe present day contains about two hundred identified oil deposits. The density of produced oil is 0.8 g / cm³ - 0.82 g / cm³, while the presence of sulfur and its components is about 2%. In the development of the field, in-circuit and contour water flooding methods were introduced, which are now used in the world practice of oilfield development. The center of oil production of this field is the city of Almetyevsk.
Multi-layer Romashkinskoye oilthe deposit during development provoked a large number of innovations, discoveries and technological discoveries. In the largest Russian deposit, strata, divided into layers, are located almost horizontally, this "pie" is divided by low permeable clay rocks. Layering is irregular, and the deposit has a large oil content and low hydroconductivity.
The company "Tatneft" is an enterpriseexploiting. Romashkinskoye oil field. Development is complicated by a high degree of internal corrosion of oil pipelines, which leads to large losses of metal, early release of pipelines from operation. This feature of local hydrocarbons requires constant monitoring of equipment, expensive repair of oil collection systems and leads to intense pollution of the environment. For example, the analysis of failure rates of the oil collection systems of OGPD Irkeneft for 1999 demonstrates that 27% of all failures are related to internal corrosion.
Romashkinskoye oil field still hasone feature: in-circuit water flooding is not just water, but with special requirements. For filling it is recommended to use water containing oil up to 20 mg / l, iron up to 2 mg / l and suspended particles of about 16 mg / l, the size of the latter not exceeding the size of about 10 microns.
By the present time in the Republic of Tatarstan there have beenMore than one hundred hydrocarbon deposits are discovered, the Romashkinskoye oil field is still the largest. Over the entire period of oil production in Tatarstan, more than 3 billion tons of oil was pumped out, the share of Romashkinskoye in the total flow is more than 70%. From the depths of the field, more than 2.2 billion tons have been selected, which means the production of reserves by 85%.
According to the established opinion in the near future,namely, in 2065, the reserves of the Romashkino giant on the balance sheet will be fully mined. At the present stage, additional exploration of subsoil resources is planned, the introduction of new technologies that will allow to extend production to 2200. According to the latest research of scientists, oil in the field is constantly fed from the depths, and therefore the production period is extended.
Nature, like a genie from a fairy tale - with one handcreates, the other destroys. There is not only replenishment of the oil-bearing layers, but their destruction, which leads to the formation of heavy oil and bitumen. Light oil of the Paleozoic period rises and oxidizes, as a result of which they are transformed into a "tire", which preserves the lower layers of oil. Scientists believe that a similar situation develops in most of the Tatarstan oil-bearing fields, not excluding the Romashkinskoye oil field. When will the giant end? The official answer to this question may be the following in 2026, but given the latest research - several centuries later.
TATNEFT Company for severaldecades is the only developer of the Romashkinskoye field. About 60% of the total production of black gold in the company belongs to Romashkinskoye NM, the remaining production occurs at Novo-Elkhovsky, Bondyuzhansk, Sabanchinsky, Bavlinsky, Pervomaiskoye fields.
The company pays much attention to the development andintroduction of new approaches in oil production and exploration, innovative technologies are tested, facilities and machines are improved. In 2006, the license to develop the Romashkinskoye field for PJSC Tatneft was extended until 2038.
The ongoing oil extraction from Romashkinskydeposits, like any other, affect the seismic situation in the region. The more intensive the development, the higher the risk of an earthquake. According to observations, in some years, up to seventy seismic events per year were observed in the development area. Also, the environmental emissions are negatively affected by technological emissions accompanying the operation of any oil industry complex. Harmful and poisonous substances enter the air, ground, pollute the water.
PJSC Tatneft applies a maximum ofefforts to preserve the environment by developing the Romashkinskoye oil field. History knows a lot of catastrophes that have changed the natural balance, and therefore Russian business seeks to minimize the consequences.
