Experimental method of simulating cementing in well cementation process

Abstract

The invention relates to an experimental method for simulating cementing in a well cementation process. The experimental method comprises the following steps: firstly assembling experimental equipment, wherein the experimental equipment comprises a shaft simulating system, a drilling fluid circulating system, a cementing system and a computer data processing system, and the shaft simulating system comprises an inner organic glass tube for simulating a drill column, an outer organic glass tube for simulating a casing pipe, an internal rotating motor and a check valve; secondly, simulating drill fluid direct circulation, direct circulation of cementing in the well cementation process, drill fluid reverse circulation, and reverse circulation of cementing in the well cementation process. The experimental method has the benefits as follows: the method is simple and easy to operate, students can personally carry out simulation operations, so as to understand direct circulation of cementing in the well cementation process, reverse circulation of drill fluid and reverse circulation of cementing intuitively and visually, the enthusiasm of the students for learning can be kindled, and the understanding and mastering of students for direct circulation of cementing and reverse circulation of cementing in the well cementation process can be deepened.

Description

technical field [0001] The invention relates to an experimental method in the field of oil and gas development, in particular to an experimental method for simulating cementing in the cementing process. Background technique [0002] Cementing in the cementing process is an important link in the well construction process of oil and gas wells. The quality of cementing will directly affect the smooth production of the well in the future, and affect the recovery capacity and life of the well. During the drilling and production practice, students can only visit some cementing equipment, such as cement trucks, ash tank trucks, manifold trucks, mixing equipment, etc., and lack of understanding of the cementing process. Not enough. At present, the explanations of cementing in the cementing process at home and abroad are only based on theoretical explanations, and there is a lack of relevant simulation teaching and experimental methods.

Problems solved by technology

But its existing problems are: it provides a wellbore device, and can simulate the changes in the wellbore. It is mainly used in the experimental analysis of cementing construction, and it is not suitable for teaching experiments. It is not easy for students to understand the whole process, and the inside of the wellbore There is an eccentric adjusting plate, and its structure is more complicated than the teaching experiment for students, so it is not suitable for systematic explanation of cementing in the cementing process for students
