Burg‘ulash eritmasi markazdan qochma separatorga kiritilib, markazda qochma kuch ta’sirida eritmani ikki fazaga og‘ir va yengil fazalarga ajratish uchun eritma tarkibidagi og‘irlashtirilgan quyqa (pulpa)ni ajtratish orqali yengillashtirilgan burg‘ulash eritmasini hosil qilishga erishiladi. Shuningdek maqolada markazdan qochma separatorni ishlatish tartibi, separatorga bo‘ladigan jarayon, eritma tarkibidagi qattiq fazani ajratishda eritmaning kolloid-kimyoviy xossalarining o‘zgarishi haqida ma’lumotlar keltirilgan. Kаlit sо‘zlаr: burg‘ulash eritmasi, markazdan qochma separator, markazda qochma kuch, rotor, val, yengillashtirilgan burg‘ulash eritmasi, og‘irlashtirilgan quyqa (pulpa), barit, burg‘ulash jarayoni, burg‘ulash tezligi, eritmani xossasini boshqarish, eritmani barqarorligi, qattiq faza, gidravlik qarshilik, burg‘ulash tezligi, suv ajratish qobilityati, korka, dispergirlash, ingibitorlar, ohak, polimerlar, shlam. TECHNOLOGY FOR PREPARING A LIGHTWEIGHT SOLUTION FROM DRILLING MUD USING A CENTRIFUGAL SEPARATOR Kholmukhammadiev A.M., Toshev Sh.O. Bukhara state technical university. Аnnоtаtiоn. This article discusses the methods and technologies for preparing and using lightweight drilling fluids applied in the drilling of oil and gas wells. The drilling mud is fed into a centrifugal separator, where under the influence of centrifugal force, it is divided into two phases-heavy and light. By separating the weighted pulp from the solution, a lightweight drilling fluid is obtained. In addition, the article provides information on the operation procedure of the centrifugal separator, the processes occurring inside it, and the changes in the colloidal and chemical properties of the fluid during the separation of the solid phase from its composition. Kеy wоrds: drilling fluid, centrifugal separator, centrifugal force, rotor, shaft, lightweight drilling fluid, weighted pulp, barite, drilling process, drilling speed, fluid property control, fluid stability, solid phase, hydraulic resistance, drilling rate, water loss capacity, filter cake, dispersion, inhibitors, lime, polymers, sludge.
This study is devoted to the issue of increasing the load-bearing capacity of highway bridges located in seismic regions. The research provides a scientifically grounded analysis of the non-compliance of existing bridge structures, designed in accordance with earlier regulatory documents, with the requirements of modern traffic loads of categories A14 and NK100 specified in the current standard ShNQ 2.05.03-22 “Bridges and Culverts”, as well as the resulting reduction in load-carrying capacity and operational safety.The paper proposes an improved structural solution aimed at enhancing the bending resistance of the main load-bearing elements by increasing the effective depth of the superstructure without performing complete reconstruction of the bridge. The effectiveness of the proposed method is evaluated based on theoretical calculations, experimental testing, and numerical modeling results, and its efficiency is substantiated.

Kirish. Hozirda dunyo bo‘yicha uglevodorod uyumlarini izlashning stratigrafik diapazonini kengaytirishga, neft va gazning qazib olinishini barqarorlashtirish va ular hajmini ko‘paytirish uchun uglevorod resurslar bazasini orttirishga alohida e’tibor berilmoqda. Bugungi kunda jahonda burg‘ulashning geologik-texnik shartlariga muvofiq samarali loy materiallari va kimyoviy reagentlarni, shuningdek, burg‘ulash suyuqliklarining oqilona turlari va formulalarini tanlash quduqlardagi asoratlar va avariyalarning oldini olishning dolzarb vazifasi hisoblanadi.
