FEATURES OF DRILLING OPERATIONS DURING ENGINEERING SURVEYS AND PREPARATION OF TERRITORIES

Abstract

The work is devoted to the creation of individual rational elements of a comprehensive regulation for the implementation of engineering-geological surveys and works on engineering preparation of territories. Experimental and analytical methods were used to study the features of the technical and technological regulations for the performance of drilling and related works, during geological surveys and engineering preparation of the territory, as well as the design of an effective system of engineering and geological testing of wells. Separate structural elements of the technology for carrying out complex borehole engineering[1]geological studies of a rock mass with complex lithological properties for the conditions of industrial areas of the oil and gas sector, the functioning of which is associated with the construction and operation of facilities for the extraction and processing of raw materials, are proposed. The basic principles of building a cycle of engineering and geological works have been developed; the parameters of the technology for the construction of hydrogeological lowering wells were calculated; the regulations for carrying out activities for the engineering preparation of the territory have been drawn up; the mining and geological features of the construction of wells in sedimentary rocks are considered. Increasing the geological information content and reliability of drilling and related work during surveys and engineering preparation of industrial territories is based on the most complete study and forecasting of the development of the entire variety of soil properties and hydrological regime. Separate components of an improved technical and technological methodology for performing work during geological surveys and engineering preparation of the territory, which is based on modern progressive industrial principles and high economic indicators, have been created; the fundamentals of an effective system of engineering-geological well testing have been developed. The data obtained are the basis for further developments in the direction of improving the quality and reliability of drilling and related work during geological surveys and engineering preparation of territories.
