DEFINITION OF FLOW-RATE OF OIL AND GAS MULTI-BRANCH HORIZONTAL WELLS WITH ACCOUNT OF PERFORATION DENSITY OF A LAYER ANISOTROPY
Article is devoted to studying of some hydraulic-gas-dynamic problems relating to development of oil and gas fields by means of a cluster of oil and gas horizontal wells (HW). For the first time this article presents salvation of some hydraulic-gas-dynamic problems pertaining to liquid and gas inflow to a cluster of oil and gas horizontal wells (HW) with account of influence of perforation density, a formation anisotropy and length of horizontal wellbores on productivity of oil and gas multi-branch horizontal wells. Some analytical dependences developed by the authors of the present article to determine productivity of oil and gas horizontal wells (HW) are given in the article to outline prospects for both oil and gas horizontal wells and formations with account of perforation density and anisotropy. Salvations of all hydraulic-gas-dynamic problems, considered above, relating to liquid and gas inflow to a cluster of oil and gas horizontal wells (HW), are received with account of perforation density of punching and anisotropy of a developed layer. The sequence of their application is illustrated by some definite examples.
