Difference between layer and well pressures in oil production

During the extraction of oil fields, pressure depth was shown in the layer and in various parts of it and on the pile in general, and around the driving wells, high pressure zones were formed. The recipient refers to the pressure difference between the pressure at the bottom of the wells and the layer - pressure depression, the difference between the pressure at the bottom of the driver wells and the pressure of the layer - pressure repression. Generally speaking, the difference between the pressure of the layer and the pressure at the bottom of the wells (perepad davlenia) is the main force that drives the liquid in the layers. In a stable operating mode, the productivity of wells is directly linked to the same pressure difference. Such a link for the buyer or driver well is expressed as follows:

qc=K1 (Pk.j.-Rk.o.)

• w=K11(Rk.x1-Rk.j.)

The resulting embryo was given to nutrents and then inserted into her woe, where it implanted.

• The data obtained can be analyzed in a table or graph. If the weight of the total particles of the mountain range is reduced to a semi-logarithmic image of the connection through their diameter, three moving points are visible in the graph

Porosity of rocks

The heads within the rocks indicate their porousness. In turn, the gag is moved by the pore coefficient.

• The ratio of the size of all heads within the mountain range (Vbush) to the total mountain sex size (Vy) is called the full (or absolute) porous coefficient.

The porous coefficient is measured in percentage or ten units. The heads of the mountain genus are of two kinds depending on the formation process - primary and secondary ones. Particles to primary bosses; the heads between the layers and the heads formed during the emergence of beds in long geological periods. Secondary chiefs, on the other hand, include newly formed large scales as a result of various tectonic movements, breakdowns of mountain ranges, meltdowns, and so on.

The shedding of the heads of the rocks will depend on their grain, shape, size - small, chemical composition. In addition, depending on the proportion of gems large and small, the heads of the mountain range will be diverse - fog. Often these gems and heads are united, forming canals of mountain rocks.
