CONSTRUCTION OF GAS WELL FOR THE DEVELOPMENT OF DEPOSITS low-amplitude

摘要

Structure gas well for the development of small-amplitude deposits relates to oil and gas industry, namely, to structures wells combining simultaneous gas exploration and production from the deposit area with limited size and floor with low gas content. The technical result consists in the creation of a gas well construction for optimizing production from a gas reservoir with small-amplitude-limited area and with a small size gas-bearing floor, providing simultaneous deposit exploration and production of gas therefrom. gas well construction for development of small-amplitude deposits includes a cased, perforated over the entire thickness of the producing formation of the vertical bore sidetracks smaller diameter directed in rock of the zone with the highest productivity and the production tubing, deflated into the wellbore to the upper side of the barrel. Upper sidetrack is lined in the region of the producing formation is perforated and its lower end is in the vicinity of the gas-water contact at least 2-5 meters. The lower side is provided with a trunk-liner filter configured to input an angle of 80-90 degrees reservoir. The overlying sidetracks, except the top, is also provided with shanks filters. The angles of entry into the reservoir of the barrel are in the range of 60 to 45 degrees with decreasing values ​​with depth tie sidetracks. Thus Filter part sidetracks proppant filled.
