NVESTMENT TECHNOLOGIES AND EQUIPMENT FOR CONSTRUCTION OF WELLS

Abstract

Ensuring the tightness and integrity of the filtration and capacitance properties of hy-drocar-bon bearing productive horizons is determined by the volume and depth of pen-etration into their structure of the pore space of dispersion and dispersed phases, the technological heterogeneous systems used, their physical and mechanical properties, the insulating properties of the forming groove, the innovative solutions (technologies, tech-nical means). Based on the results of the general-ization of theoretical, experimental, field research, recommendations are given on the formulations (compositions) of technolog-ical colloidal and hardening systems to solve the problem (raising the maintenance-free period of effective well work) in the construction of wells in fields with complex geological and technological conditions for their development and development.Methods are proposed for designing a well design that takes into account the joint per-ception of excess loads by the system casing cement stone; formulations of washing biopolymer salts compositions and oil-filled materials for a wide range of thermobaric condi-tions for the occurrence of oil and gas reservoirs; the design of downhole hydrosensitivity generators on a grouting mortar pumped through them. The proposed investment solu-tions with positive results are tested during the construction of wells.
