Abstract

Enerji talebinin giderek arttığı günümüzde petrol, doğal gaz ve jeotermal kaynakların sondajı ve üretimi ekonomik açıdan büyük önem taşımaktadır. Bu süreçlerde karşılaşılan en büyük zorluklardan biri yüksek işletme maliyetleridir. Bu nedenle maliyetleri düşürmek enerji üretim sektöründe ve yüksek enerji tüketimi olan sektörlerde faaliyet gösteren şirketler için stratejik bir hedef haline gelmiştir. Petrol sahaları akışkan özelliklerine göre Newton ve nano-Newton olarak adlandırılmaktadır. Üretimleri ve oluşturdukları maliyetler birbirinden farklıdır. Özellikle nano-Newton (ağır) petrollerde, petrol rezervinin kimyasal özelliklerine göre farklı oranlarda kimyasalların bulunması ve bunların yüzeye doğru hareketi sırasında ısı kayıplarının neden olduğu fiziksel değişimler üretim hatlarında tıkanma sorunlarına neden olmaktadır. Bu tür sorunları önlemek için birçok maliyetli yöntem kullanılmasına rağmen çalışmada kuyu çimentolamasında kullanılan çimentoların ısı yalıtım özelliklerini artırarak maliyetlerin düşürülmesi ve bu sorunların önlenmesi amaçlanmaktadır. Bu çalışma kapsamında, mevcut petrol-doğalgaz ve jeotermal sahalarında en yaygın kullanılan G sınıfı çimentoda, hacimce %5'ten %30'a kadar artan oranlarda kimyasal katkı maddeleri ve yüksek fırın cürufu ve genleştirilmiş perlit gibi mineral katkı maddelerinin farklı ikame oranlarında kullanılmasının, G sınıfı çimento harcındaki yoğunluk değişimi, basınç ve eğilme dayanımı gibi temel mekanik özellikler, gözeneklilik gibi fiziksel özellikler ve ısıl iletkenlik gibi yalıtım özellikleri üzerindeki etkileri çoklu regresyon analizi ile incelenmiş ve ilişkiler denklem ve grafiklerle verilmiştir.
Çalışmanın amacı, kuyularda kullanılan G sınıfı çimentoya standartlara uygun ilaveler yapılarak üretim kesintilerinin önlenmesi, sürenin mümkün olduğunca kısaltılması, iş kayıplarının önlenmesi ve maliyetlerin düşürülmesidir.

Abstract

In today's world where energy demand is increasing, drilling and production of oil, natural gas and geothermal resources are of great economic importance. One of the biggest challenges encountered in these processes is high operational costs. For this reason, reducing costs has become a strategic goal for companies operating in the energy production sector and sectors with high energy consumption. Oil fields are called Newtonian and nano-Newtonian according to their fluid properties. Their production and the costs they cause are different from each other. Especially in nano-Newton (heavy) oils, the presence of chemicals in different proportions depending on the chemical properties of the oil reserve and the physical changes caused by heat losses during their movement towards the surface cause blockage problems in production lines. Although many costly methods are used to prevent such problems, the study aims to reduce costs and prevent these problems by increasing the thermal insulation properties of the cements used in well cementing. Within the scope of this study, the effects of the use of chemical additives at different substitution rates and mineral additives such as blast furnace slag and expanded perlite at increasing rates from 5% to 30% by volume in the G class cement, which is the most widely used in the existing oil-natural gas and geothermal fields, on the density change in the G class cement mortar, basic mechanical properties such as compression and bending strength, physical properties such as porosity and insulation properties such as thermal conductivity were examined by multiple regression analysis and the relationships were given with equations and graphs.
The aim of the study is to prevent production interruptions, reduce time as much as possible, prevent work losses and reduce costs by making additions to the G class cement used in wells in accordance with the standards.
