Abstract
This study presents a chemical lost circulation agent with some distinct advantages that make it suitable for use in controlling severe leakage during drilling process. It is a granular solid with irregular shape and able to bridge or fill the cracks and other porous or faulty formations into where the drilling fluid is lost. Then this agent will undergo a chemical reaction with water, and the reaction products fill between particles and bind tightly lost circulation agent particles to each others or to the rocks at the lost circulation zone, thus effectively enhance the compressive strength of the cementing body formed by the agent and prevent lost circulation. Temperature, particle size, and additives added have been shown to have a significant influence on the consolidating rate and compressive strength of the cementing body. In addition, the cementing body has certain permeability, and the permeability can be adjusted, so this agent is proper for use to control lost circulation in reservoir.
Highlights
Lost circulation is a common and complex problem that has deleterious, and sometimes even disastrous consequences for drilling operations
This study presents a novel self-binding lost circulation agent with some distinct advantages that make it suitable for use in controlling severe lost circulation: (1) This agent is a granular solid with irregular shape, and particles do not react with each other
According to the actual condition of loss formation the product can be used with different sizes and distribution and it can bridge or fill the cracks, crevices, fissures, and other porous or faulty formations into which the drilling fluid is lost and can effectively plug leakage channel
Summary
Lost circulation is a common and complex problem that has deleterious, and sometimes even disastrous consequences for drilling operations. This study presents a novel self-binding lost circulation agent having some distinct advantages that make it suitable for use in controlling severe leakage This granular material can effectively bridge or seal the problem formations. It may react with water, and the reaction product can bind tightly lost circulation agent particles to each other or to the rocks at the lost circulation zone, effectively enhancing the compressive strength of the cementing body formed by the agent. PREPARATION AND PHYSICAL AND CHEMICAL PROPERTIES OF THE PROPOSED SELF-BINDING AGENT
